Zone Sense values Watch vs App

[A Former User]

Hi,
I have noticed that the values that the watch shows me after exercising do not match with the app values.
For example in the watch shows 9:55 in anaerobic but in the app shows 7:00
I have the last iOS beta version
Thanks

@SGIPE-232R5 I have the same issue; Race S on Android. I think it is a problem discussed in several forums and in my opinion, negates the value proposition of zone sense. I have been using Zone Sense for two months with cycling being my primary activity. The value proposition of Zone Sense for me is to provide me real-time feedback via the watch when working out. That is, on that given day, where am I at, in real-time, regarding my aerobic vs anaerobic thresholds? But I don’t trust the watch data. When I compare it to the Zone Sense App data post-workout it can be significantly different. In most cases, the watch will tell me that I spent 30%-40% more time in my anaerobic zone than the Android APP. In my opinion, the Android APP reflects a truer picture of my effort. I can provide supporting data but many already have. Zone Sense has very little value to me post-workout. Until Suunto rectifies this problem the purported value proposition just isn’t there. I need to trust the watch data and I don’t .

@Stephen-Kenny I’ve begun week four with a RaceS plus Polar H10 (old pod, new strap). No experience of cycling but the Run activities line up quite nicely between watch and app. I don’t carry a phone/camera with me so had to memorize the numbers today: 1 hour 8 minutes run, Watch 53-something minutes Aerobic, 4m53s Anaerobic; SA 51m40s Aerobic, 5m13s Anaerobic. And the SA graph of the ZS Anaerobic peaks corresponds with when I saw the crossover on the watch.

Obviously people have different hardware when it comes to HR belts/straps but I wonder if we also differ in the DDFA algo ‘affinity’ to our personal HRV system. Perhaps some people fall way outside of the model norm?
