First off, this app is definitely worth the annoying ads. Just put up with them — unless you’d rather pay four bucks for the “premium” version, which is the exact same app but without the ads.As for the features, I found my missing Ace 2 in about 20 minutes (I had no idea where it was but I knew it was somewhere near my device). The app first led me to the wrong Ace 2, but then once I fixed the error (turned off the other device’s Bluetooth), it brought me outside into my yard. I was kind of confused because the little arc kept going back and forth even though I kept walking in the same direction, but eventually it evened out as I walked into my driveway. The arc led me to my car and sure enough, my Fitbit was right underneath the seat. I would never have thought to look there if it wasn’t for this app.The only reason I am taking off a star is because the app won’t tell you what direction you should look to find your Fitbit. It took me a lot of trial and error just to figure out what the app was trying to tell me, and I feel like even a free app should have some kind of direction sensor.Overall, this is a great app and I recommend it to anyone who has lost their Fitbit as long as you’re willing to spend some time looking for it.

If you are like me and have lost your Fitbit in your house/garage this is a great free app. I am pretty sure however that this app. WONT help you find your Fitbit if it is truly lost(meaning you have no idea where it is). If like me, you know for sure it's in your house somewhere this is a great app. As long as you have A DEVICE to use it with THAT IS NOT PAIRED TO YOUR FITBIT! This app only works with something not paired to your Fitbit so you may need to borrow a friends phone download it on there and then look. It's sort of like playing that game where you find something by asking "am I getting hotter or colder?" And hotter means you are closer.... this app shows you when you are getting closer... my Fitbit was under a couch cushion where I never would have looked!

This is a no frills app that does what it promises. I have misplaced my Fitbit several times, and every time it has located it ... inside shoes, inside the clothes hamper, inside jacket pockets, inside closets, under seat cushions. The premise is very simple: an arc spins on the screen when you're not nearby and starts to become solid as you get closer - the more of the arc that is solid, the closer you are. It's not complicated and it works. Sometimes ads pop up which become annoying, but only mildly so. Click the X and keep going or pay a small one-time fee and skip the ads. Caveat: It won't work with the device that it is synced with, so momentarily you will need to turn blue tooth off on that synced device while searching. For example, I have mine synced to my iPhone, so I turn off blue tooth on my phone and use the app on my iPad. I guess if you only had one device and no partner or friend willing to download the free app, then it won't work. (Developers, if this caveat incorrect, please feel free to say so for other users.)

Lost my Fitbit Charge HR so purchased this app. Big mistake and waste of money. IPhone couldn't find Fitbit so help feature said to turn off Bluetooth on device paired with Fitbit and use another device not paired with Fitbit. What if you don't have another device? I did have IPad so tried using it to find Fitbit. That didn't work either. Didn't matter which room in the house I was in, the arc stayed the same and said I was getting closer however; I never did see the "cold" - "warm" or "hot" notification. In the meantime I had to close pop up advertisements every 30 seconds in order to view the search screen.After an hour of walking through each room in my house I gave up and began searching without the app. Fortunately I found my Fitbit, made sure it was fully charged and then tried using t he app again. Even holding my IPad next to the Fitbit with the app running it couldn't find my Fitbit and yes Bluetooth was on. Don't waste your money on this one!
