Intro
I’ve had a lot of trouble with my Fitbit HR, or more to the point, with the auxiliary programs. Two different Dell computers can’t find it – Bluetooth driver problems perhaps? My Windows phone can’t sync to it 99% of the time. Then I used an old Android phone, but I realized it was set up with my spouse’s account. And there’s no way to change it from the app itself. What to do?
The details for Android devices
Short of a full Fitbit app uninstall, I found what works is to go to the same place where you would uninstall an app, namely, Settings|Application Manager. Scroll to Fitbit. Touch Clear Data.
Then next time you launch the Fitbit app it will walk you through an account setup so you can associate it to your account.
This is the only practical way to do it, and the Fitbit site itself is useless for advice on this topic.
Conclusion
I’ve shown how to change the associated account from one user to another on an Android device. You cannot do it from within the app itself so you could waste a lot of time aimlessly looking around. Hopefully this post will help some people like me who are confounded as to why something so simple should be made so hard.
