Discrepancy in HR statistics between watch and app

[Yves Jenni]

Today I recorded a short interval workout with the Polar H10 on the Suunto Run. The HR graph on the watch seems to be correct, but the app shows something different. The last interval and the 3-minute cooldown are missing. But the time is correct

Note: Android App 6.0.2, Suunto Run Firmware 3.19.20

Also using the H10 strap and having similar problems. What I think is happening here is that the heart rate recordings somehow get delayed / desynced in the app (and everywhere else, sports tracker, runalyze, strava, you name it). Yesterday, I was doing some hill sprints. I did the first hill sprint at roughly 26:12 into the run and the corresponding heart rate spike happens at 29:28. Later I did a sprint at 40:29 and the heart rate spike happens at 45:48. The gap is getting wider the longer the run is. When I stop the recording, the last X minutes of heart rate recordings are cut. When not using the strap, the HR spikes happen when they should, without delay.

@Yves-Jenni Hi, it happened to me too, reported here

@Tomi
Same here, we are talking about 1km of delay. Hope the will fix it

Patch 3.20.22 massively improved the situation, but there’s still a gap between pace and HR that widens over time.
