Works in the woods
Lost my Fitbit in the woods behind my house, lots of damp leaves and underbrush. I tried using the alarm function several times, with no luck. Thankfully, I was close enough to the house that I had a wifi connection, so I downloaded Find my Fitbit. It took a few minutes, and as the directions say, you need to go slow, but I indeed found it. For giggles, I set the alarm one more time. Standing above the Fitbit, I could not hear the alarm, the leaves absorbed all the noise.
The only drawbacks are that the app does not provide the direction, only relative proximity. Also, even when next to the Fitbit, the app does not read the maximum 7 of 7 bars.
Overall, a very useful app, and much better than spending the money for a new device.
