I am using Runtastic / adidas running for running activities on the Apple Watch. At least for the first 5 minutes the Apple Watch does not measure HR and afterwards measurements are highly fluctuating. Either skin is too cold or the watch is broken.
Any similar impressions?
Apple Watch Series 6, watchOS 7
Thanks for your reply. It happens in all apps during physical activity.
My findings are that the apple watch needs to be worn about 2 cm below the wrist, otherwise measurements will be as shown.
Best regards
Hi ol_mainhattan,
If we understand correctly, you have some concerns about the Apple Watch not recording heart rate during a run recorded in Runtastic, is that right? If so, do you notice the same behavior happening in the Workout app also?
The resource below provides more information about how the heart rate is recorded, and tips on improving the results.
Monitor your heart rate with Apple Watch
If you find this only happens in Runtastic, we encourage you to contact the app developer directly using How to contact an app developer
Please let us know if you have any other questions!
All the best.
Apple Watch HR measurements are quite wrong during running
