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”. ### 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 ### 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! ### 4/5 — Janky but... helpful *2020-06-11, version 1.0.7* I was freaking out because I lost my Apple Pencil for the hundredth time (that pesky little thing!) and i downloaded this app. At first it was really confusing because the devices don't have names. 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 — 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! ### 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. ### 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.) ### 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 ### 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 ## Frequently asked questions about Bluetooth Smart Scanner ### What does Bluetooth Smart Scanner do?
