Thanks for your detailed reply. I see the colors on the app and they make sense. But I was wondering on the band itself. There is a big purple box and then blue spikes. The app has different colors.
Also, I wonder if the activity tracking is correct. e.g., this morning I woke up and walked from room to kitchen and back to room. Physically it is around 30 steps. Plus/minus 2 steps. But the band shows 3.
Then I woke up in the night to go use the restroom and the band doesn’t show any timea awake at all. I think the motion sensors and algo are not yet tuned or accurate.
