Heart Rate Data not showing in activity app

Hi

As the message indicates, your Apple Watch did not record sufficient heart rate readings to create a chart.

For swimming workouts, keep in mind that Apple advises that water may prevent or reduce the accuracy of heart rate sensor performance during swimming workouts.

For other workouts and more generally, Apple also advises that, even under ideal conditions, Apple Watch may not be able to record a reliable heart rate reading every time for everybody.

For the best performance from the heart rate sensor during workouts, ensure that you wear your watch snugly (but not too tightly) on the top of your wrist. Apple suggests that you consider tightening the band before starting a workout and loosening it again afterwards:

Your heart rate. What it means, and where on Apple Watch you’ll find it. - Apple Support

Other issues that can impact sensor performance include skin perfusion and wrist tattoos.

If you are concerned about a possible hardware defect or software issue, then I suggest that you contact Apple Support (mail-in service may be available, if required), make a Genius Bar reservation or visit an Apple Authorised Service Provider for assistance:

The following steps may also help:

On your iPhone, in the Watch app, go to: My Watch (tab) > Privacy > if they are not already enabled, turn on Heart Rate and Fitness Tracking.

On your iPhone, in the Watch app, go to: My Watch (tab) > Workout > turn off Workout Power Saving Mode.

If you then remain concerned about a possible hardware defect or software issue, then I suggest that you contact Apple Support (mail-in service may be available, if required), make a Genius Bar reservation or visit an Apple Authorised Service Provider for assistance:

Hey,

I had the same problem and I thought it is because of new iOS update. I was going to downgrade my OS but then I tried hard reboot and it worked for me!

To do hard reset, press and hold both the Sleep/Wake and Home buttons simultaneously for at least 10 seconds, until you see the Apple logo. You can let go of both buttons after the Apple logo appears.

Hope, it helps!

My app was also working fine until I paired it with the iPhone X. The weird thing is, it worked fine with the iPhone X for two days. Then the heart rate data stopped appearing in the workout app. The heart rate data continues to show up in the Health app (so I know its being recorded), but the workout app shows insufficient data to display a graph for both a walk and a run.

If you find a solution to this problem please let me know.

Same issue. Watch Series 3 and iPhone 7. Works fine if I pair with an external Bluetooth HR monitor. HR appears on watchface during the workout. But no summary data graph for the workout at the end, and no HR data appear in the Health app.

Hi everyone:

I can’t explain why it works, but the solution for me has been to tighten my watch when I run. The heart rate sensor works and records my heartbeat in the health app when I run and wear it a little loose, but it doesn’t record the information in the workout app. When I tighten it just for my run, it starts recording. The few times I forgot to tighten the watch before my run, it didn’t record properly.

The only thing I can think of is the sensor is less sensitive after a software update? I really don’t know. But it has worked 100% of the time when I tighten the watch. No re-pairing or resetting required.

Hope that helps! Good luck!

I am having the same issue. All heart rate data shows in the Health app, however ‘chart unavailable’ in the activity app. It makes no sense.

If any one finds a resolution please share.

Thank you! Unpair & re-pair worked for me as well. 🙂

Actually it only worked for 1 exercise, after that I got the same DATA UNAVAILABLE error in the Activity app.

Any other option to fix it? Thank you!

The same is true for me. Until recently the watch collected heart rate measurements very well for my runs. I tried all of the above(settings were all right from the beginning) and nothing helped?

Reset iPhone settings didn't help either.

I've just changed to iPhone X and it started acting up since I migrated to the new phone.

I'm having the same issue. Apple have been unable to trace why this is happening as for me, it only happens when I do a running activity. Incredibly annoying!!!
