Watch App Improvements


A new complication.

There's a new complication for the modular face. 

Modular Large

This shows your last heart rate reading with an indicator as to whether is was lower or higher than the previous one. It also shows the average, minimum and maximum heart rates in regular time for the current day. 

Fast Start.

Launching HeartWatch from the complication is now much faster and it now goes directly to the last HeartWatch face that you selected. For example, if you were previously viewing the "Pulse" face, then the complication will take you directly into this face. 

The Watch App

Crown Navigator.

We have re-engineered the Watch app for better performance. Instead of loading all HeartWatch faces when you select one from the menu, it only loads one at a time. This speeds things up by reducing how much memory is used and also lets you choose your default HeartWatch face when launching from the complication. 

Crown Navigator

To choose the HeartWatch face, you now simply turn the crown. This displays the new Crown Navigator and lets you quickly select which face you want to use. You'll feel a bump as each icon is highlighted. Once you've made your selection, stay in that position for at least 0.5s and the new face will be set. 

To get back to the main menu, turn the crown downwards until there are no highlighted icons. 


You can also swipe from the centre of a HeartWatch face. Swipe your finger to the right to get back to the menu and up or down to cycle through the faces. 

Ending Workouts.

You can now also swipe in any direction from the centre of the HeartWatch workout face to display the end workout menu. 


Better Control.

There's now more control over alerts. You can enable and disable the alerts in the HeartWatch iPhone app, by pressing the red settings cog in the top right corner and selecting "Notifications". We've added a new option for workouts. If you are using a workout app on the watch other than the inbuilt HeartWatch workout face, then the alerts will automatically switch to use this value as your high alert instead of the regular one. 


There's also a new settings view available from the Watch app main menu. This lets you turn alerts on and off directly from the watch. It also lets you review your alert settings.

Reliable Alerts.

It's important to remember that alerts rely on background time granted by the Watch OS. This means that to get more frequent updates you need to have the HeartWatch complication on your Watch face and preferably also keep HeartWatch in your Dock. HeartWatch 3.1 has also improved reliability of alerts over the previous version. 

External HR Monitors

What's This?

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. 


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:

Watch Bluetooth Settings

  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. 


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

Sleep Improvements

A Single Badge.

There were many requests for a single heart rate badge for sleep tracking. HeartWatch now creates the badge for time in bed rather than multiple badges for each "Asleep" entry. 

Awake Time.

If using an app that creates multiple Asleep entries in the Apple Health database, periods of being awake are now shaded as above. 

Support for Multiple Apps.

Some customers like to use multiple apps for tracking sleep. Previously, this could corrupt the sleep tracking in the HeartWatch app. Therefore, HeartWatch will now automatically choose a single app as the source for its sleep tracking data. It will first check for AutoSleep, then HeartWatch, then whichever app it finds first. For non HeartWatch sleep tracking it will display the name of the app that it is using in the Sleeping Heartbeat section. 

Calendar & Dashboard for People that Don't Wear the Watch to Bed.

If you don't wear your watch to bed, yet still want to see sleep recharge in the calendar and the sleep gauge in the dashboard, you can now do this by using the Apple Bedtime feature or by using our new AutoSleep companion app. 


We've created a new companion app for fully automatic sleep tracking. It's entirely optional, and, for people that would rather continue to track sleep using the precision of a start and stop button, this option is still a part of HeartWatch. 

We created this as a separate app as 

a). It's seriously tricky stuff under the covers and, for technical reasons needed to be a separate app.  


b). We wanted to keep things simple!

So, if you are interested in tracking sleep without needing to press any buttons at all and without having to load a new Watch app, read on. 

You can learn all about AutoSleep here. There's really nothing else like it. We've done a huge amount of testing with lots of different people and the results have exceeded expectations. Best of all, for a limited time, it's currently 33% off normal price. 

AutoSleep & HeartWatch

HeartWatch has full, automatic support for the AutoSleep app. Other than for initial setup, you don't even need to open the AutoSleep app to have it work with HeartWatch. 

Sleep Recharge

AutoSleep Recharge

If you wear your Watch whilst sleeping and use AutoSleep (no buttons to press), the sleep recharge section has some changes. 
  • The percent recharge is now based on actual time asleep as a percentage of your sleep requirement. 
  • There is a new quality figure which display's AutoSleep's sleep rating calculation of your sleep. This is for both the last night and an averaged value for the trailing seven days*. 
  • The actual time asleep is now displayed under the quality figure. 
Note, for the first week of use, the trailing week figures will be a mix and match until a full week of AutoSleep data is available. 

Calendar & Dashboard

The calendar recharge view and the dashboard sleep gauge will also automatically use AutoSleep data. 

For people that don't wear their watch to bed, the good news is that AutoSleep is still able to track your time in bed and include this in the recharge and dashboard sections. 


What is it?

If you need to share your heart rate & vitals, activity or workout data with a family member or medical professional, or simply to analyse in more detail yourself, then there's a new add on export feature to HeartWatch. Best of all, this new add on feature is a free trial with unlimited use until Jan 31. 

How Does it Work?

Export plugs into your Dashboard. To use it is a simple 1, 2, 3:

Dashboard Export

  2. Choose the time frame by pressing the time selection control at the top. 
  3. Press either of the AVG. BPM, WORKOUT or SPEEDOMETER gauges and you'll see the Export option. 

What is Produced?

Depending on the gauge pressed, a different set of data is produced. Each will create an email with summary text, gauge representation and one or two spreadsheets containing the results.
