Works perfect!
I lost my Fitbit One while camping and I just used this app to find it. I did not have to unpair or force close anything. It just started showing me my signal.
This app narrowed the location down to my tent, and I found it in my sleeping bag! Best money ever spent on an app! I just regret missing a bunch of steps this morning!
