As a watch it’s OK but useless for anything else including what it is suppose to do. My Fitbit Charge 3 continually disconnects from any phone I set it up on. I am continually have to uninstall the app, reinstall and set up Fitbit again. Even when it appears to be working it randomly freezes or stops recording exercise sessions, like bike riding, walking or running. I really regret purchasing these for my wife and I but I guess we live and learn. Maybe my review will make some other potential purchaser think twice.
I note that the web is full of people complaining about this problem and it’s pretty clear that Fitbit couldn’t care less, they’ve got your money.
