The Apple Watch uses an optical heart rate sensor which shoots light through your skin to determine your heart rate.

Apple Watch built-in heart rate sensor logs less data points than Polar H10 chest strap sensor Downsides to Apple Watch Built in HR Monitor However, for anything more vigorous there are a few downsides to the built in heart rate monitor. You can’t really train at a specific heart rate zone if you can’t rely on faulty data points.įor walking and just daily wear the Watch is great for monitoring heart rate. Other times I’d notice my heart pounding and the display would show 45 bpm which I knew was absolutely wrong. I’d look down at my Watch while running and see the spinning heart icon (meaning it was trying to read the heart rate, but couldn’t find one) and no heart rate would display. I wanted to experiment with heart rate zone training (training at a specific heart rate for a period of time) and found that just using the Apple Watch’s heart rate monitor was not ideal. You might be thinking, why would you buy a heart rate monitor when the Apple Watch already tracks heart rate? Heart Rate Zone Training Failure

There's no other workaround, if you need real time for longer periods, or while the user is not using your app, you will need to use an specialized wearable.Last March I decided to purchase a separate chest strap worn heart rate monitor, specifically the Polar H10 Bluetooth Smart HR Sensor, to use with my Apple Watch when tracking my workouts. Watch OS 2 request the sensor to measure automatically ( in background) every 10 minutes minimum.

Do you know how to it? I would need some background task that is executed every 5-10 seconds on the iPhone. Then I saw that there's some kind of background functionality that watches the HealthKit itself and revokes the app from background and you can do something.(enableBackgroundDeliveryForType) This doesn't seem to work for heart rate (the Apple Documentation says for things like steps this doesn't work, I guess heart rate is one of those). This works, as long as the app is in foreground. My next approach was to query the HealthKit on the iPhone every five seconds for new data. That doesn't work because as soon as the screen turns black on the watch, it stops sending. But now I have the problem that I can't sync that with a server. There is new heart rate data in the HealthKit every five seconds. I need to make an app that records heart rate data in near real time and send this data to a server as soon as possible.įirst I took this approach: Watch os 2.0 beta: access heart beat rate
