Vertical sleep time different watch vs iOS app
-
I restarted using a Suunto Vertical and I was pleasantly surprised to see that the sleep recording (start/end times) were close to reality [in the past, I’ve seen Vertical sleep detection as being hit and miss].
When I looked in the iOS app, I noticed that the sleep duration is different (shorter), with the same wake-up time, but different moment for the sleep start.
Is that something common for other people? I thought that the device is the “master” - how come the app is doing overwrites?
