Like others, I was hoping to have HR, O2 and movement all tracked through the Go2Sleep ring/finger tracker. A lot of data does go into the SleepOn app. The movement data is not as good as SAA but there is data on “toss and turn” and “sleep levels” which do not show up in SAA when the Go2Sleep tracker is integrated. Kinda sucks since Bluetooth can only connect to one item so it’s either my Galaxy Watch/SAA (which would give me HR and movement) or the Go2Sleep/SAA (which gives me HR and O2).
So, I do get most of the data I want with Go2Sleep. It would just be nice to have it all in one place.
