Disclaimer: I realize this watch only cost 20 or $25, so obviously it’s not going to be perfect.
I was hoping to replace my 4 year old Fitbit but I find myself wearing two watches instead. My main interest is in the sleep function. I have horrible insomnia and I like to keep track of how many hours of sleep I get every night. My Fitbit tracks this pretty good. The Wyze, not so much.
It almost never shows awake time (almost an impossibility).
If I wake to go to the bathroom, it decides I must be awake for the day and stops tracking.
There’s no editing of your sleep time.
Battery status:
With the Fitbit, you get a notification when the battery reaches certain level.
The Wyze gives you nothing. You have to manually check. My watch keeps going dead because of this.
As for the rest, I can only imagine how accurate it must be.
On the plus side, I like the notifications, shortcuts (they need to be expanded though) stopwatch (needs an always on screen option)
Personally, is gladly pay $35 - $40 for these functions.
