Updating to HeartWatch 4

Not Seeing Any Data Following Update

This is due to some health permissions that have not been granted. This is more common in Watch OS6. Its an easy fix following these steps:

1. Go into the iPhone Settings app on your iPhone. Choose Privacy, Health. Press HeartWatch and then press all categories off.

2. Power the iPhone off and on as per this link. (i.e. shut the iPhone down completely so that it restarts with the  on screen). https://support.apple.com/HT201559

3. Power the Watch off and on as per this link. https://support.apple.com/HT204510

4. Now in iPhone Settings, Privacy, Health, HeartWatch press all categories on. Make sure that all the switches are turned on

6. Now go into HeartWatch iPhone app

7. Press the little Settings Cog on the top row (image below)

8. Select Advanced Settings (image below)

9. Select Rebuild History (image below). A red heart will appear and days will start to pre-fill. Note this may take a few minutes as it loads up 12 months of data.

Here is a Health Permissions video which shows the main steps.

Everything should now be ok after the above. Please contact us via the Support page if still stuck.

Missing Health Data Since Updating to iOS 14

Apple reported a bug in iOS 14 that was impacting some users health data. This has since been fixed in the iOS14.2 update. We suggest updating if you are experiencing a similar issue on iOS 14


Pulse Not Working on Watch

Refer to the above steps for 'Not Seeing Any Data Following Update'. This is also due to some health permissions that have not been granted.


Repeated Health Permissions

This may be related to a legacy health permission issue. Ensure you have the current HeartWatch version installed onto the iPhone and also the Watch, then open each app on both the iPhone and the Watch and this should solve it. If still no luck, it may be a corrupt Health record, send us an email and we offer some additional steps to try.


Complication on Watch Not Updating Data

This could be due to a few reasons:

  1. You may need to make sure you have the correct Complication setup, as HeartWatch has multiple options to select from for Pulse, Daily Avg, Sedentary Avg and so on. This is all setup from your Watch Settings menu, go to Watch Use Complications for more instructions.

  2. If you are not seeing any data on the Complication at all, refer to the above steps for 'Not Seeing Any Data Following Update'. This is also due to some health permissions that have not been granted.

  3. If your alerts are not updating quickly enough, refer to the section below called 'Complication and Alert Updates'

Complication and Alerts Updates

How it Works & How to Get the Best Performance

Because the Watch is capable of running lots of apps, Apple uses various strategies to decide whether an app is granted background time. Here’s an explanation.

Short Answer:

1. Always go into the app and back out when you put your Watch on your wrist. This tells the Watch that you want to use it.

2. Make sure you have the HeartWatch complication on your Watch face.

ALSO NOTE: If you put the Watch on the charger for even a single minute, then put it back on, this resets the processing budget for all complications and makes them much faster. This is useful to do in the morning if you have worn the Watch overnight.

Explanation:

Firstly, in order to get the background processing time in the Watch to be able to do alert monitoring, you need to have the HeartWatch complication on your watch face.

It is also best practice to go into the app when you first put your Watch on. This tells the Watch that you use the app and that it is important to you and ensures that any background services are started.

To add a complication to your Watch, press the clock screen firmly until you feel it push back, then press customise. Swipe and you will be able to set up the complication.

The complication should be updating every 10 minutes. This same process also does the alert processing natively on the watch. It will only alert for things that it knows you haven't seen though. The Apple Watch takes background readings every 2-10 minutes so this timing ties in well.

Troubleshooting:

If you are having a problem, then:

1. Go into the Apple "Watch" app on your iPhone.

2. Scroll down until you find HeartWatch in the app list.

3. Select this and uninstall the app.

4. Reboot your watch by pressing the crown and side button until you see the 

5. Once it is back to life, after about 5 minutes, go into the Apple "Watch" app on your iPhone again, scroll down to the HeartWatch app again, select and install.

Once the app has been added, then go into HeartWatch select pulse face and then press crown back to clock. The complication should now start updating automatically. For information on setting up Complications, go to Watch Use Complications for more instructions.

Common Problems

Where is the Watch App?

This is a lovely little bug that has become much more popular in iOS 13. If the Watch app isn’t showing in the Apple “Watch” settings app on your iPhone then here's what to do.

You fix this by "turning it off and on".

The Watch app should now appear in the “Watch” settings app on the iPhone so that you can install it to the Watch.


Cannot add Complications?

Sometimes the Watch setting app on iPhone doesn't get informed that there are shiny new complications.

You can resolve by adding them directly on the Watch itself. Refer to the official Apple support page on setting up Complications here. For additional information on the Complications available in HeartWatch, refer to Complications on our Watch Use section.


Why is it draining my Watch battery?

Well, it isn't really. There's an Apple install bug that sometimes doesn't end gracefully and keeps the comms open between your Watch & iPhone and drains your battery.

It’s very important to perform all these steps in the exact order. Especially 2 & 3 are these cause crashed OS services to restart.

  1. Remove the Watch app (via the Apple “Watch” settings app on your iPhone - black icon with picture of Watch).

  2. Power the iPhone off as per this link. (i.e. Shut the iPhone down completely so that it restarts with the  on screen). https://support.apple.com/en-au/HT201559

  3. Power the Watch off and on as per this link. https://support.apple.com/en-au/HT204510

  4. After a couple of minutes, install the watch app.


I've got a Shiny New iPhone! How do I keep my data?

Everything is stored in the Apple Health database.

There are two ways to restore this on a new iPhone:

Using iTunes (my preferred method as it is faster and much more reliable)

  1. Once you are happy your old iPhone is up to date and have decided on what you want to carry across to your new iPhone, turn on flight mode on your old iPhone.

  2. Connect to iTunes on your Mac or PC.

  3. Perform a backup, but, make sure that you have turned on the password protection option. As long as you do this, it will save all your encrypted data, such as health data, network settings passwords etc.

  4. When you get your new iPhone, connect to iTunes and restore from the backup of your previous iPhone.

Using iCloud on iOS 11 or higher

If on iOS 11 or higher and you have previously enabled iCloud health synch then you can restore your health data by signing into your iCloud account on the new iPhone. Then go into the Apple Health app and you’ll start to see all the data appearing. It can take quite some time for everything to show up. Sometimes a whole day.

If everything fails to show up in the app, then is sometimes due to permissions not being carried across. Usually deleting and re-installing the app solves this. But remember to press Keep on the second message that you get when you delete the app.

Finally. Always unpair the Watch from your old iPhone and set up as a new Watch on your new iPhone. The automatic method Apple provides is not very reliable.


I just updated iOS on my iPhone / WatchOS on my Watch and things stopped working.

The most common problems are updating Watch without updating iPhone, Updating iPhone without Watch, or doing automatic updates. Even doing things properly, there are some Apple Health synch bugs where system services are not correctly started after an update. Step 4 below usually fixes those.

When updating iPhone or Watch, here's what's important.

1. Never, ever do automatic updates. They break things.

2. Always update your iPhone first. This is in iPhone Settings, General, Software Update.

3. Then update your Watch. This is in "Watch" app (black icon with a picture of a Watch on it), General, Software Update.

4. When the update has finished, power both devices off and back on again.

Power the iPhone and Watch off and on as per these links.

i.e. Shut down completely and restart.

iPhone: https://support.apple.com/en-au/HT201559

Watch: https://support.apple.com/en-au/HT204510

In most cases, everything should now be just fine.

If not, then the update may have removed health permissions. Yes, honestly, they do this sometimes. You can resolve that problem below in the respective sections for each app.

Finally, in extremely rare cases, the update can corrupt the Watch's pairing to iPhone. You can solve that problem by unpairing then re-pairing as a New Watch per this link: https://support.apple.com/en-au/HT205025


Family Sharing has Stopped Working

This one has been a bit more common in iOS 13.

Many folk have been able to solve via this method:

https://www.iphonejd.com/iphone_jd/2019/04/this-app-is-no-longer-shared-with-you.html

If not, then you will need to contact Apple Support as they run the App Store and set up and control family sharing. Here's the link to use to do this: Contact Apple Support

Crashes

Got a new iPhone and iPhone app is crashing

If you restored the new iPhone via an iCloud backup instead of iTunes then this has a minor problem in that they forgot to apply heath permissions via this method.

If you delete the app (note it gives two prompts, say Yes to the first question and Keep to the second question to keep your data) then re-download it will be fine.


iPhone App crashing on start

If HeartWatch is crashing on start, this is caused by HealthKit permissions not being correctly updated when you upgraded your iOS. This can be fixed by deleting the HeartWatch iPhone app, rebooting both the iPhone and Apple Watch and then re-installing and going through the setup process in the HeartWatch iPhone app.

As above, if you delete the app (note it gives two prompts, say Yes to the first question and Keep to the second question to keep your data) then re-download and it should be fine.

Troubleshooting

Not Seeing Any Data or Watch App not Working

There are two mains reasons for errors.

These are either Watch / iPhone Settings Issues:

  1. Is bluetooth turned on? Some people accidentally turn it off. It’s easy to do.

  2. Are either of the devices in flight mode?

  3. Did the Watch go into low power mode (< 10% battery)?

  4. Do you have a passcode on your Watch? This is required for background heart rate data so needs to be unlocked while wearing.

  5. In Passcode in the Apple Watch settings app have you turned on Wrist Detection? This is required for background heart rate.

  6. In Privacy in the Apple Watch settings app, both Heart Rate & Fitness Tracking need to be turned on.

  7. Do you have a prominent wrist tattoo?

Or,

Apple's iPhone & Watch software gets more complicated all the time and therefore has more scope for possible problems & bugs. This especially common after an iOS or WatchOS update.

1. You can fix so many problems simply by "turning it off and on".

2. Power the iPhone and Watch off and on as per these links.

i.e. Shut down completely and restart.

iPhone: https://support.apple.com/en-au/HT201559

Watch: https://support.apple.com/en-au/HT204510


That usually fixes it. Otherwise the problem is usually due to health permissions. It may look like you have granted all health permissions but sometimes iOS just decides to ignore this.

To reset Health permissions and iOS and Watch health services and ensure everything works on the watch going forward, please perform these 7 steps. It is important to do all steps in this exact order especially steps 3 & 4 as this restarts the crashed system services on your iPhone and Watch.

  1. Remove the app from your Apple Watch by going into the Apple “Watch” app, on your iPhone scroll down until you find AutoSleep and then remove it.

  2. Go into the iPhone Settings, Privacy, Health. Press HeartWatch and then press all categories off.

  3. Power the iPhone off and on as per this link. (i.e. Shut the iPhone down completely so that it restarts with the  on screen). https://support.apple.com/en-au/HT201559

  4. Power the Watch off and on as per this link. https://support.apple.com/en-au/HT204510

  5. Go into the iPhone Settings, Privacy, Health. Press HeartWatch and then press all categories on. MAKE SURE THAT ALL SWITCHES ARE TURNED ON.

  6. Now go into HeartWatch iPhone app and this should restore all permissions

  7. Wait 5 minutes and then Install the watch app (using the Apple “Watch” app if required.


Last chance saloon. If you get to here then it means the app has not been correctly installed.

It’s very important to perform all these steps in the exact order.

***Especially 2 & 3 are these cause crashed OS services to restart.***

  1. Delete the HeartWatch iPhone app. Make sure you keep any data associated with it when it asks though. Note when you delete the app you get questions. The Keep question is the 2nd one.

  2. Power the iPhone off and on. i.e. Completely off and then back on as per this link. https://support.apple.com/en-au/HT201559

  3. Power the Watch off and on. https://support.apple.com/en-au/HT204510

  4. Download the HeartWatch iPhone app again.

  5. Start the HeartWatch iPhone app and go through the setup process carefully accepting permissions. MAKE SURE THAT ALL SWITCHES ARE TURNED ON when asked about health permissions.

  6. After about 5 minutes, install the Apple Watch app (if required).


How do I enter my Date of Birth?

There are two mains reasons for errors:

(note: for mysterious reasons there are multiple places to enter DOB but this is the right one):

Date of Birth is stored and maintained in the Apple Health app. This is an app that comes pre-installed on your iPhone and has a white icon with a red heart. To enter your data of birth:

In iOS 12:

1. Go into the Apple Health app. If you can’t find it, swipe right on your home screen until you get to search and then type in "Health".

2. Press the icon in the top right corner, then select Health Profile.

3. Press the Edit button in the top right corner.

4. You can now edit your details.

In iOS 13:

1. Go into the Apple Health app. If you can't find it, swipe right on your home screen until you get to search and then type in "Health".

2. Press the icon in the top right corner, then select Health Profile.

3. Press the Edit button in the top right corner.

4. You can now edit your details.


What are the tiles, badges and stuff?

They give you an at a glance view of your heart rate data. Refer to our comprehensive HeartWatch site for more information on each of the tiles and images in HeartWatch


How do I use the Watch app to start a workout or sleep etc. etc.

The Watch does lots of things. You can learn how it works and what it does here.


I want to set custom alerts for my workouts.

Refer to our Watch Use section for setting HR zones alerts during workouts


My background alerts are delayed/not working.

Firstly, in order to get the background processing time in the Watch to be able to do alert monitoring, you need to have the HeartWatch complication on your watch face. It is also best practice to go into the app when you first put your Watch on. This tells the Watch that you use the app and that it is important to you and ensures that any background services are started.

To add a complication to your Watch, press the clock face firmly until you feel it push back, then press customise. Swipe and you will be able to set up the complication. Refer to the official Apple support page on setting up Complications here.

The complication should be updating every 10 minutes. This same process also does the alert processing natively on the watch. It will only alert for things that it knows you haven't seen though. The Apple Watch takes background readings every 2-10 minutes so this timing ties in well.


Not seeing Heart Rate, Energy or Sleep Data

This is normally due to HealthKit permissions. Heart Watch reads your heart rate data via your iPhone's Health Data Store. When you first launch the app it will ask for your permission. It's important that you provide your ok for all this information as it is required for all the required calculations. If you were accidentally a bit quick doing this and missed granting permissions, then you can do this at any time by going into iPhone Settings, Privacy, Health, selecting Heart Watch and turning the required permissions on.

If you are not seeing anything you have entered on the Watch, such as sleep or measurements then pay particular attention to the write permissions.


Not seeing automatic Heart Rate readings

If you have disabled "Wrist Detection" in your Watch settings, General panel, or have set your watch to low power mode, this can result in your Apple Watch no longer taking automatic heart rate readings throughout the day.


Delays in Seeing Heart Rate or Sleep Data in the iPhone app

Occasionally you will experience a minor delay while your Watch writes health data to your phone and the health store does its updates. These are generally minor. You can pull the Heart Watch summary screen down at any time to get the latest update, this is shown in our Navigation page.


Not Seeing Data on Watch App

If you are seeing your heart rate data in the HeartWatch iPhone app, but not seeing any data on your HeartWatch Watch app, then this is likely a HealthKit permission problem. To fix, follow these five steps.

1. Remove the Watch app from your Watch.

2. Reboot the Watch by simultaneously pressing the Crown & Side button until you see the Apple logo appear.

3. Reboot the iPhone by simultaneously pressing the home button and the sleep wake button until the Apple logo appears.

4. Once both devices are back to life, wait a few minutes until they are both happy and communicating.

5. Re-install the Watch app.

This should fix most cases of not seeing data on the Watch.


Not seeing Workouts

When you are active, by default your Apple Watch will not take automatic heart rate readings. When exercising, you need to tell your Watch that you are doing a workout. This changes the heart rate monitoring mode to the high sampling rate.

The easiest way to do this is to start a workout directly in the HeartWatch app. You can also either use the inbuilt Apple Watch workout app or whatever your favourite workout is that writes workout data to the Apple Health database (HealthKit).

Always remember to end and save the workout. This will write the workout information to the Apple Health database and allow it to show in the HeartWatch iPhone & Watch apps.


The Watch app has become slow or unresponsive

A quick reboot of the Watch will get everything performing well again. They are fancy computers on your wrist so they can get a little tired after a week or so. You can do this by pressing the crown and side button simultaneously until you see the Apple logo. This will take about a minute. After that everything will be super fast again. It's good to do this once a week when you put the Watch on the charging dock.


How do I control Alerts

Alerts are all configured directly from the Watch app under the Settings menu. Open your Watch app, scroll down to Settings and you will see a menu item for Alerts. Additional information please refer to the alerts section in Watch Use on configuring alerts.


Watch data different to iPhone data

Your Watch communicates with your iPhone app during the day and night, so sometimes it may be a little behind and not exactly in sync. To refresh your iPhone app data, pull down on the HeartWatch Today view until you see the HeartWatch logo appear and it will refresh. All sections on the Today view also have a quick refresh icon you can tap, as shown in the Navigation section.


My Recommended Goals Are Decreasing

Depending on your goal level this may well be the case. As your Habit Status is tracked over a longer period of time, you may have achieved well over your targets for consecutive days, so the app will start to reduce your targets. You can use the minimum function or update your goal level to something more extreme, but this is not a bug, but part of the smarts of the Habit Status tracker. Refer to Activity for more information.

Daily Heart Rate - What it Means

This section explains some key concepts behind the design of HeartWatch and how heart rate data is represented.


Daily/Regular Heart Rate

Regular heart rate is a term used in Heart Watch to isolate the readings your watch takes in the background every two to ten minutes from those readings you take during a workout or those taken during sleep.

Workout readings are more likely performed under physical stress and an elevated heart rate. By isolating regular heart rate from workout heart rate, Heart Watch can present a more accurate picture of your day to day heart health.


Daily/Regular Zones & What They Mean

It is generally understood that a regular resting heart rate is from 60-100 bpm though resting heart rates from 50-60 bpm are common amongst healthy individuals.

By default, HeartWatch uses the following colours and zones to present your regular heart rate data, both in heart badges and charts.

Keep in mind that this is not medical advice. If unsure of anything, always consult a medical professional.

  • Red: Greater than or equal to 100bpm. A sustained resting heart rate above 100bpm may indicate tachycardia. If your regular heart rate badge is mainly red, you should consider seeing a health professional.

  • Purple: Greater than or equal to 80 & less than 100bpm. Though this does fall within the parameters of a regular resting heart rate, it is on the high side. Depending on your level of activity or consumption of stimulants, this may indicate that you aren't particularly fit/healthy if you are consistently seeing that your badge is nearly all purple. To help in determining how active you have been, HeartWatch overlays your active energy level when you press the badge to see the details of what makes it up.

  • Blue: Greater than or equal to 55 and less then 80bpm. This is recognised as a healthy resting heart rate. Ideally your badge should be at least half blue. The more blue, the healthier your heart is likely to be. You should however, consider the type of day you have had though. If you have been very active, then purple may be a reflection of what you have been doing (see above).

  • Pinkish Brown: Lower than 55 and greater than or equal to 40bpm. If you can see a significant pinkish brown centre in your badge, and you are experiencing fatigue, weakness, dizzyness or feel faint, then this may indicate bradycardia. If you don't have any symptoms, and particularly if you are a well trained athlete this likely isn't a problem. Again, consult your doctor especially if you are experiencing symptoms.

  • Brown: Lower than 40bpm. Unless you are a very highly trained athlete, a brown centre in your badge or even seeing a percentage of readings in brown is likely not a good thing. If you are experiencing any fatigue, weakness, dizzyness or feeling faint then even more so. Probably a good idea to see your medical professional.

Waking Heart Rate - What it Means

Studies have shown that your waking heart rate is an important measure of your basic fitness level and a strong predictor of your cardiovascular health. A normal adult range is from 60 to 80 beats per minute. Athletes can have a range between 35 to 50 beats per minute. Generally speaking, the better shape you are in, the fewer beats per minute.

Having a high waking heart rate can be an indication of poor cardiovascular health and can indicate things such as hardening of the arteries and restrictions in the diameter of your blood vessels. If your waking heart rate is over 80bpm, then you should consult your medical practitioner.

For athletes, monitoring the variance in waking heart rate can be useful in monitoring overtraining.


Taking Waking Pulse if you wear or don't wear Watch to bed

There are two ways to capture your waking heart rate, depending on whether you use HeartWatch's sleep tracking feature or not.


If Using Sleep Tracking

If using sleep tracking in the Watch app, there is a handy Take Pulse option when you finish sleeping. Using this will ensure the most accurate way of tracking your waking pulse.


If Not Using Sleep Tracking

Whilst still in bed, put your Apple Watch on to your wrist & enter its PIN. This will trigger an immediate heart rate reading in the background on your Apple Watch. However, reaching across and moving around might cause your heart rate to elevate slightly. The way around this is to open the HeartWatch watch app, choose the Pulse option and touch the gauge. This will let you capture five live readings and then buzz you when it finishes.


Waking Pulse Customisation

By default, if you do not use sleep tracking, HeartWatch will use the first reading after 4AM that it finds. You are able to customise this in the settings menu (the red cog in the top right corner of the iPhone app) by changing the hour to something more appropriate for you.

If you do not want to see the Waking Section then you can also stop it from being displayed by turning off the switch under the Show Waking Section heading within the Settings menu.

Working Heart Rate - What it Means

When you start and end a workout on your Apple Watch, Heart Watch will use this information to isolate and present this heart rate information in a separate section. Each workout will appear with its own badge and all workouts for a day consolidated under a zonal summary.

Ideally you should start the workout using the HeartWatch watch app as this will also show you which zones you are in.


Workout Zones & What They Mean

For workouts, the zones are based on percentage of max heartbeat which is very popular with “zonal” style training.

Percentages are used to give a common reference over different ages & levels of fitness and to allow individual adjustment based on training level.

By default, HeartWatch uses the following zones:

  • Aqua = moderate zone (50-60% of max) - won’t increase fitness/strength/endurance but good for health, recovery, warm ups, cool downs etc.

  • Green = fat burning zone (60-70% of max) - lowish effort, predominantly uses fat for energy.

  • Yellow = aerobic fitness zone (70-80% of max) - builds functional capacity, lung capacity, respiratory rate, numbers & size of blood vessels etc, metabolises fats & carbs around a 50/50 rate.

  • Red = anaerobic threshold / intense zone (80-90% of max) - getting faster & fitter via more intensity.

  • Bright Red = extremely intense (90-100% of max) - full on effort for short bursts only during interval training. Purely anaerobic.

Anything below 50% of your max heart rate will show in the default resting colours. Something to look out for is if you are also seeing light or dark brown readings and experiencing light headedness during your workout. Rapid fluctuations from red to brown are of particular concern. This may indicate an underlying heart problem that you should discuss with your medical practitioner.

As with any exercise, be sensible. Unless you are an elite athlete, or experienced trainer, it is likely sensible to stay yellow or lower as you build your fitness and adapt to training loads.


Workout Customisation

In the HeartWatch settings menu (the red cog in the top right corner of the iPhone app), you can customise how the various heart rate zones are presented in the workout section. Each colour can be associated with a percentage of your maximum heart rate. Your maximum heart rate itself may also be changed, by default, it is based on your age.

Sleep Tracking - What it Means

The sleep section relies on you capturing both heart rate & when you started and finished sleeping. This is made somewhat easier in HeartWatch as there is a sleep tracking option built into the Watch app.

However, you don't have to use this. If you have a favourite iPhone app (or even another Watch app like AutoSleep) that you use for sleep tracking/alarm that writes sleep data into HealthKit, you can still use this. You do however have to wear your Watch whilst sleeping otherwise you won't be tracking your sleeping heart rate nor your restless energy.


Using AutoSleep with HeartWatch

If you are using our automatic sleep tracking app AutoSleep then you can learn how this works on the AutoSleep Tips page by clicking here.


HeartWatch Inbuilt Sleep

If you are using HeartWatch's inbuilt sleep tracking feature using the Watch app, then the following information explains what it all means.


About Restlessness Tracking

Your Apple Watch captures your active energy and basal energy whenever you are wearing it. This includes while you are asleep. This is, like heart rate data, written to the Health database on your iPhone. The HeartWatch app reads your sleep start and finish, the basal energy you used and any active energy. It uses an algorithm to compare the active energy to the basal energy and determines how restless you were during your sleep. This is then graphed over your heart rate in a top down format (where the top y axis = 0). It also uses a z axis by plotting activity that has occurred in overlapping times to form a deeper green which indicates greater intensity of movement. In practice, any waking events can be seen as bars that have descended the red line.


Sleep Recharge Estimate

This restlessness data is then used along with how long you have slept to determine to what extent you've "recharged your batteries".

By default, this works based on an average of 8 hours quality sleep. If you feel that you require more or less hours of sleep per night, then you can change this in the info section.

The trailing week recharge battery symbol is based on the weighted average of up to your last seven days' sleep. This a fairly non-scientific analysis of your sleep but does provide a handy indicator as to whether you are starting to incur a sleep deficit. You'll likely notice anything below 90% and especially feel the effects of anything below 80%.

Future updates of the app may include automatic sleep recording and a deeper analysis of sleep zones. We'd love to hear your feedback.


What is Basal Energy

Basal energy expenditure (BEE), also known as basal metabolic rate (BMR) is the amount of energy needed to carry out fundamental metabolic functions, such as breathing, ion transport, normal turnover of enzymes and other body components, etc.

So while sleeping (and also throughout the day), there is a base (basal) rate of energy that you burn while doing absolutely nothing.

The Apple Watch records this whenever you are wearing it.

Now, active energy is any energy you burn over and above that required as basal energy. This is due to needing to fuel physical movement.

Again, your Apple Watch also captures this.


How is Restlessness Calculated

For restlessness calculations, HeartWatch identifies the basal energy requirement that your body had while asleep. It then looks at active energy expended during this time and uses an algorithm to identify the intensity of this activity versus baseline.

The simple percentage you see is, the active energy you have burned over and above your basal energy requirements which provides a nice way of seeing how restless you were.

The green energy graph you see overlaid over the sleeping heart rate is where and when this occurred, the strength and intensity.

The energy graph has a reverse y axis, where the top = 0 and the bottom is maximal. It also has a pseudo z axis by overlaying entries that overlap each other to cause a brighter shade of green

Glossary of Terms

Wellness Terms

  • Daily bpm - your daily heartbeat is measured when you are not exercising or sleeping

  • Sedentary bpm - is a subset of the daily heartbeat readings where you have been still for at least 5 minutes prior to the heartbeat sample

  • Sleep bpm - is measured from the time you went to sleep and awoke

  • Recharge - is measured from the time you slept compared to your goal which is setup in Settings. Recharge is your body's time to recover from your activities and get ready for the next, measuring how restless you were overnight and calculating how much of your sleep requirement has been met

  • Waking bpm - your waking pulse is considered one of the gold standards when measuring your resting heart rate. This is automatically captured when you start to wake from sleep if using the HeartWatch sleep function or using our AutoSleep app

  • HRV - Heart Rate Variability (HRV) is a method for assessing the effects of stress on your body, by measuring the variances between your heart beats. This is automatically captured by your Apple Watch overnight or by performing a breathe session on your Watch

  • BP (am) - Blood Pressure is the measurement of the pressure of the blood in the artery in the morning (am)

  • BP (pm) - Blood Pressure is the measurement of the pressure of the blood in the artery in the afternoon (pm)

Habit Status has been designed exactly for this habit tracking, automatically showing your current status along with recommending move, step & distance goals based on your individual results and goal level to monitor your habit changes.

Workouts

  • Cals/Kjs - A calorie (cal) or kilojoule (kj) is a unit of energy. A calorie is the amount of heat needed to raise the temperature of one gram of water by one degree Celsius. Our bodies store and burn calories as fuel

  • Time - this is the duration of the workout, shown in hours and minutes

  • Load - this represents your response to exercising, quantified by the intensity and duration of each workout you perform

  • Recovery - your heartrate change following exercise. Your Recovery Heart Rate, the speed at which your heart rate returns to normal after exercise, can indicate physical cardiac condition

  • Pace - how fast you are moving and is usually expressed in relation to how fast you could run a km or mile

  • VO2 Max - is the maximum rate of oxygen consumption measured during incremental exercise. Maximal oxygen consumption reflects cardiorespiratory fitness and endurance capacity in exercise performance.

External HR Monitors

You may not know this but you can connect external heart rate monitors such as the Polar H7 and the Wahoo TICKR wirelessly to your Apple Watch and leave your iPhone behind.


Why Use Them

These monitors record samples at one reading per second and measure your heart's electrical activity rather than measuring the result optically per your Apple Watch's inbuilt sensor. When your workout isn't rhythmic like walking and running, such as weights workouts or is very high intensity, the optical sensor will sometimes skip recording heart rate readings when it doesn't have complete confidence in the result. In these sort of cases, external monitors are not affected, and will continue to deliver constant readings.


How to Setup

There's a one time setup, then it is all automatic.

Firstly, in HeartWatch iPhone app:

  1. Press the settings cog.

  2. Select Advanced Settings.

  3. Turn on "Enable 15 sec samples". This is to handle the enormous volume of data that these external monitors produce and ensure that you get clear easy to read results for your Workout Badge and detailed analysis.

Note: You can also set this to 1 minute samples. This is useful if you want to wear the external monitor for all day use or very long periods of exercise.

To connect the external monitor to your Apple Watch:

  1. Put the chest strap on and click the module into place via its press studs.

  2. Now, on your Watch, press the Crown to go to the menu, select Settings and then Bluetooth.

  3. You'll see the external monitor appear in HEALTH DEVICES*.

  4. Touch this and it's now connected. You never need to this again.

* If it doesn't appear, just exit the settings and go back in. It usually shows up the next time.

Now, in the future whenever you click the press studs into the chest strep your Apple Watch will use the external monitor in place of the inbuilt optical sensor.


External Monitors in Workouts

The built in HeartWatch workout face will now update the workout gauge at one second intervals when the external HR monitor is connected.
