I turned on the sound and it kept getting closer and closer, and soon enough my mom dug it out of our stupid couch. ### 5/5 — Downloaded and found my Fitbit within 2 min!! *2017-11-16, version 1.0.7* Love it! Thank you sooo much developers of this app! I lost my Fitbit last night at school. I had it in my back pocket, so I feared that it was lost at school, maybe in the bathroom. I *hoped* it would be in my car or at home somewhere. I downloaded this and figured out which set of numbers/letters (as noted in other comments) it must have been by which one was moving up and down the most drastically when I moved around the house. For example, the Bluetooth speakers I have downstairs stayed relatively at the same strength as I moved around upstairs. I moved from room to room, literally holding my phone an inch above the floor, until I spotted it. If you’ve seen a Fitbit tracker, you know how small these things are!! I found it under my bed—never would have looked there. It must have flown out when I took off my pants when I got home last night. Anyways, so glad I didn’t lose it. This app is awesome! ### 5/5 — Will this work if ur Apple Pencil has not battery? *2017-09-19, version 1.0.7* I lost my Apple Pencil also I think it has no battery ### 5/5 — Great app *2017-05-29, version 1.0.7* Is a bit confusing! The lower your number the closer you are. Hit stop then turn on sound. Found my fit bit no prob, in my couch in 2 minutes. My number was -43. :) ### 4/5 — Needs better instructions *2017-04-13, version 1.0.7* I took away one star because there is a little bit of a learning curve to use this and had to do some google searching to find helpful reviewers that explained how it worked but it DOES work! I think a tutorial or basic guide would make this perfect. This has been a lifesaver for me trying to find all those pesky "little" thugs that I swear just walk away on their own. ### 5/5 — Found my fitbit in 5 minutes *2017-03-29, version 1.0.7* Used to find my fitbit. Once it got within a few feet it was -40 and I was right on top of it. ### 5/5 — Found my Fitbit *2017-03-27, version 1.0.7* I knew my Fitbit was in my house but I was not able to find it on my own. It took ~5 min to narrow the search down and locate it with this app. Yay! ### 5/5 — Awesome! *2017-03-24, version 1.0.7* Found my Fitbit in 5 minutes after searching without it for an hour! ### 5/5 — Saved my life *2016-12-30, version 1.0.7* So I came home from my art studio today, and set my iPad and Apple Pencil together on a stand in the kitchen. I was very tired, so I went up to take a nap. Well when I came back from said nap, my pencil was GONE! I thought I may have dropped it outside so I went on a search. I was losing hope then I googled ways to find my poor pencil. I found several recommendations for this app. So the download commended. I opened it and set out to find my beloved pencil. It took about an hour because I wasn't really sure how to use the app, but I finally found it in the drawer of the stand. I would be lying if I said I didn't think my little sister put it there to play a joke on me. Not funny. I am an artist, and this pen pays my bills along with the iPad, so I cannot afford to lose this pen. Thank you so much!!! ### 5/5 — Found Apple pencil! *2016-11-21, version 1.0.7* I lost my Apple Pencil yesterday when some kids were using it (I didn't realize it was lost until last night). By opening the iPad Pro and looking at notifications to see the battery levels for the iPad and pencil, that wakes the Pencil up. Then I used this app to look for the strongest signal (-30 dBm) in this case. The app actually identified the Apple Pencil after about ten minutes. Then I dug down into the couch at that point - and there it was! Thanks for saving me lots of money! ### 5/5 — Diagnostic tool *2016-08-31, version 1.0.7* My phone has Bluetooth connectivity issues. This is the proof I need to confirm that I'm not crazy!!! Thank you for the free app. ### 5/5 — I don't care about lack of instructions *2016-08-30, version 1.0.7* Well okay I do. I'd love a vendor lookup or a hint or whatever. But this thing helped me find a misfit flash that I've been looking for for MONTHS If you're having the same issue make sure you've unpaired the flash. ## Most critical reviews (10 lowest-rated) ### 1/5 — App weird and scary DO NOT DOWNLOAD *2019-12-16, version 1.0.7* Ok I opened this app because I’ve been searching for my Apple Pencil everywhere so this one comment told me to turn sound on first of all the noise is horrible and just scared you and second of all It doesn’t have names so how can I find what I’m looking for? So ya DO NOT DOWNLOAD if ur looking threw the reviews to see if it works and yes this comment is real not fake. ### 1/5 — Doesn’t work *2019-08-24, version 1.0.7* This is a horrible device, don’t waste your $, they want you to upgrade to premium I had a device sitting in one place not moving and it couldn’t find it. It fluctuated between -34 to -70... what a joke ### 1/5 — Not A Very Good App *2019-01-08, version 1.0.7* I couldn’t find my headphones with this app, and the names of the devices it scan won’t even show up. It’s just blank. Just shows letters and numbers than a name section that’s blank. That app needs more instructions and improvements. ### 1/5 — Useless *2016-03-27, version 1.0.7* How does this even work??? All I know is the numbers didn't change even with my Fitbit 1ft away on my wrist. I took it off and the numbers were all still nonsense Deleted the app immediately. ### 1/5 — Wasted my time *2016-02-10, version 1.0.7* There are no instructions, all it seems to do is indicate the power level as such proximity of a Bluetooth device. I saw no option to be able to modify the name of a unit - I have 3 fobs and woudl like to name each individually. I am sure this must be possible as each I presume has it's own signature, but how to do it ??? No idea as there are no instructions. Totally wasted my time. ### 2/5 — Confusing *2018-08-18, version 1.0.7* I lost my pencil two days ago just in my house, and I’ve been going crazy trying to find it. I tried using this app, and although I get the numbers, it’s so confusing trying to figure out which one of the signals it’s getting is what I’m looking for. I’ve been around all the rooms I’d been hanging around that day and some other random places, but the signals never indicate that I’m getting close (they just stay in the -80 to -90 range). It’s possible that the pencil died, which I guess this app wouldn’t be able to locate, but when I tested it on my bluetooth speaker (on and charged), nothing came up. Like, no new devices found, and all of the shown signals indicate that I’m pretty far away from all of them. If I’m doing something wrong, please tell me! I just wanna find my stuff :((( ### 2/5 — What...? *2018-01-02, version 1.0.7* I honestly don’t understand how to use this… I have a lot of Bluetooth devices in my house but I already knew that would be a bit of a problem for me but none of my devices had names and I couldn’t understand anything! I think it should come with instructions but I do think that it’s better that some of the other apps I’ve tried… I’ll try a bit longer but I won’t get my hopes up :/ ### 3/5 — I mean I found what I was looking for *2021-10-30, version 1.0.7* App is extremely hard to figure out, read reviews they are very helpful. Found iPad pencil in 5 minutes. Might have just been I got lucky though ### 3/5 — Hard but useful *2019-01-04, version 1.0.7* It is hard to use and as soon as you move around the numbers go crazy. I lost my airpods. I used this app and I found them. When you get to around -50 it means it’s like a foot away. ### 3/5 — Not perfect but it works. *2016-08-19, version 1.0.7* I had to use my head a bit and be slow and patient but it did find my Fitbit in a drawer in another room! ## Most praised reviews (10 highest-rated) ### 5/5 — Very useful. Should have been part of iPhone Settings app. *2023-07-22* If you know what a dB is this app becomes immediately informative. Sure, it would be nice to se the device names but it’s not that hard to figure out which signals are changing as you walk around. This just became my “Hearing aid Locator App”. ### 5/5 — It Really works *2020-11-13, version 1.0.7* Thank god I love this app, my Apple Pencil has been missing for a WEEK. and it was found after only five minutes with this app. If you lost something you NEED to download this app! ### 5/5 — It works !!! *2020-05-17, version 1.0.7* Awesome app! I lost my AirPod and this app helped me find it. It helps if you turn on the sound though. I walked around my house and when I got close to where my AirPod was it started beeping. I’m so thankful! ### 5/5 — turn the sound on and you’ll be amazed *2019-12-09, version 1.0.7* read all the bad reviews and was reluctant but thought I might as well try it. I noticed some people said it should come with instructions and it does.. I clicked the information button on the top left and you have to turn the sound on. I turned it on then pressed scan and head a chirping and found it right away. this app is fantastic, just gotta turn the sound on ### 5/5 — Works! The UI is bad, but it's free *2019-11-12, version 1.0.7* Thanks, previous reviewer, for the tips on how to use this app. Like they said: -90 = 10 feet away, -80 = 5 deer away, -65 when I was right next to it. Walk slowly, because it takes a second to re-scan as you move. This app helped me find my Fitbit that I'd been looking for the past 5 days! I found it within 2 minutes with this app. (It was hiding in the shadowed corner of a houseplant!! How it got there, I have no idea.) ### 5/5 — Fantastic app *2019-08-04, version 1.0.7* Was able to find the bluetooth speaker at the beach transmitting bad music. Hijacked the speaker. Problem solved. Awesome ### 5/5 — Found Apple Pencil! *2019-01-11, version 1.0.7* I have been looking for my Apple Pencil for a week and a half, I was starting to lose hope, when I found this app. The names threw me off, but I decided one of them had to be the pencil. I was waking around each possible room and watching the signal, when I was about to lose hope... I saw it reached -30... I looked down and under the little cabinet there it was! Life saver! ### 5/5 — Does what it says *2019-01-04, version 1.0.7* 5 thumbs up. Tip: 1) identify name of your Bluetooth device 2) do a scan with this app 3) stop the scan 4) go through each scanned device to find yours-will prob need to click on each one 4) once identified, just scan on your device 5) hint for your device; signal closer to -1 is best. Mine kept jumping to 127 but then when back to negative numbers which got bigger (closer to zero) when I got closer. FYI: I found my Bluetooth at -40 (not -1). ### 5/5 — Worked Great! *2018-01-19, version 1.0.7* Lost my Bose Revolve Bluetooth speaker and I had searched high and low and couldn’t find it. I used this app and traced the signal and read prior reviews that the lower the negative number the closer you are. The lowest read I found was around. -50 and I was within 3-4 feet and found it under one my bureaus where it had rolled being that it oval shaped. Saved me tons of time. ### 5/5 — Great job! Amazing! *2017-12-10, version 1.0.7* I lost my BLE device and this little app tracked it down for me!
