I tried both without wires and with wires, I bought a separate Apple adapter and connected it via the iPad cable included, but pairing does not occur either physically or via the Lightblue utility. In the search in the application, it shows a multiplied device, but the connection does not occur with any of the clicks. ### 4/5 — Very unstable *2025-08-09, version 5.3.3* Suddenly stopped connecting apple pencil. Sometimes it connects sometimes doesn’t ### 2/5 — Не могу подключить apple pencil *2025-07-26, version 5.3.3* Перо у меня первого поколения а планшет 2025 года,искала все способы подключения,везде говорили об этом приложении.раннее перо было подключено к старому планшету,но после я его продала полностью очистив планшет и отдав как новенький.то есть можно считать,что я отключила перо от старого устройства,но даже так невозможно подключиться новому планшету к нему.в поиске ближайших устройств мне его показывает,пробую подключаться,ничего,совсем,а после кнопка вообще серой становиться и невозможно подключить.у меня было лишь два раза,когда подключение хотя бы продвинулось дальше,когда показывало попытку подключение и запись disconnect. И на этом все,далее подключение никак не менялось,попытку подключаться игнорируется.пробовала подключаться тремя разными переходниками на планшет и перо,тоже ничего не менялось совсем,даже использовался оригинальных переходник,который идет вместе с пером.я не могу купить новое перо,но и рисовать хочу.подскажите,может есть еще какие то способы? ### 5/5 — bestest *2025-07-26, version 5.3.2* using to test my iot peripheral implementation, and it does everything i need and then some. ### 5/5 — Wow! *2025-07-18, version 5.3.3* This is such a useful app!! ### 2/5 — Apple pencil *2025-06-10, version 5.3.3* Is asking for the code that ‘shows’ on Apple Pencil before allowing a connection. Didn’t do this before. Tried 1234, didn’t work. Shame. ### 5/5 — Good *2025-06-10, version 5.3.3* Helped to connect Apple Pencil 1 to new iPad a16 ### 5/5 — Helpful for battery levels *2025-05-19, version 5.3.2* It’s hard to get a true reading of battery levels for my Heart Rate straps I use for cycling. The best way I’ve found is to use this tool to get an honest number. Previously, I’d use an app and it would use bars or some other metric and it didn’t even seem accurate. What an awesome tool! ## Most critical reviews (10 lowest-rated) ### 1/5 — Inaccurate *2026-06-26, version 5.3.6* Found my thing but bc it was my memory. 98 when I was in the same room with it. ### 1/5 — Complete lies *2026-05-16, version 5.3.6* Preview images show names of devices, which it in-fact does not do, you have to name them manually.. lets not even get started on its scan or connect for device alone, 5ft away from a device with bluetooth and it doesn’t even show up in the app at all, and dont even get me started with a smart watch, it doesnt even see that and thats less then 2 feet away at any time.. Completely broken with absolutely no point to the app other then seeing your device names(once input manually) ### 1/5 — The app does not work *2026-04-23, version 5.3.5* Lost my Fitbit while out hiking. Found out on the Fitbit app that there is no good way to locate it. The best suggestion they had was to see the last time it synced. These days it always tries to sync so there’s no record. This app was mentioned in the Help files as a solution for iOS users. After walking for hundreds of yards, I started to doubt that this was even doing anything. Why not just open iOS settings, and look at my Bluetooth device devices that are connected? Eventually, I found my watch on the trail. That was with my own eyes. The iOS settings did indicate a connection. Went back to LightBlue to test it, toggled, a few buttons, no indication at all! Dvlpr: Please reach out to Fitbit to remove this as a possible solution, finding one ### 1/5 — Not Useful Due To *2026-01-12, version 5.3.5* The app could not be used by me due to the apps design. The app uses very light colored fonts on a white background with no way to change or use dark mode to help use the app. Larger fonts would be nice to. ### 1/5 — Why?… *2026-01-05, version 5.3.5* When I tried to pair my Apple Pencil to my iPad it said to “write the code on the Apple Pencil” but like WHAT CODE??? IS THERE A SECRET SCREEN I CAN’T SEE ON THE APPLE PENCIL?! ### 1/5 — Não funciona no iPad Air 4 *2025-12-24, version 5.3.5* O iOS 26 não deixa o aplicativo funcionar, a Apple Pencil 1 não consegue conectar, resolvam esse problema, quero usar a Apple Pencil 1 no meu iPad Air 4. ### 1/5 — Can’t connect *2025-12-14, version 5.3.5* It shows Apple Pencil but whenever I try to connect IT NEVER, CONNECTS IT ALWAYS JUST SHOWS CONNECTING FOR LIKE A ETERNITY ### 1/5 — todo mal *2025-08-09, version 5.3.3* tarda muchísimo en conectar y hoy ni siquiera pude ### 1/5 — Una aplicación para perder tiempo *2025-07-24, version 5.3.3* Llevo dándole 2 oportunidades a esta aplicación me parece nada necesaria me parece que se pierde menos tiempo comprándote el nuevo por que la aplicación no serve de absolutamente de nada innecesaria no es compatible con nada a su que me parece una una pérdida de tiempo ### 1/5 — Maria *2025-06-08, version 5.3.3* Does not work with me ## Most praised reviews (10 highest-rated) ### 5/5 — Found My Fitbit *2026-07-14, version 5.3.6* I Tried around 3 apps and couldn’t find it, on this app, the lower the signal of the number became, I knew I was closer, and eventually found it. ### 5/5 — pencil *2026-07-06, version 5.3.6* it connected my pencil to my iPad just fine! the password is 1234 for the Apple Pencil 1st gen ### 5/5 — Found my oura ring!! *2026-05-18, version 5.3.6* Great app!! Helped me find my Oura ring!!! ### 5/5 — Helped me find my lost FitBit! *2026-02-27, version 5.3.5* I lost my FitBit in my house and the forums suggested this app. You do have to keep connecting to it as they don’t maintain a steady connection but it led me right to it. Fantastic for helping you track down your devices and free too! ### 5/5 — Works like a charm! *2026-02-19, version 5.3.5* Lost my Fitbit. Was able to walk around my home and was directed to the laundry room. Found it in the hammer there. Highly recommended app! ### 5/5 — Found my vibrator *2026-01-01, version 5.3.5* I lost my toy somewhere in the dungeon below my house, it’s the Deep Impact Screamer 5000 Turbo and I was so worried I wouldn't be able to take the entire Brazilian rugby team the next day without it. The app is fantastic! ### 5/5 — Lifesaver *2025-12-20, version 5.3.5* for the life of me, I couldn't connect my first generation Apple Pencil to my 10th generation iPad. This app saved my life absolutely do get it, 100 per cent recommend ### 5/5 — Works Great *2025-12-03, version 5.3.5* I needed to find a missing Oura Ring, this app was able to isolate which room and where in that room by tracking the signal strength. It even identified the manufacturer ID. ### 5/5 — Found *2025-09-30, version 5.3.4* Lost my fitbit. Immediately saw to my relief that it was somewhere in the house because it connected by name. Figured out smoothly that it was upstairs, then in the bedroom, then I found it under the mattress where it must have slipped off of when I tucked in the sheets when making the bed. Glad I found this app! ### 5/5 — MADRE SANTA, SE PASARON DE GOD *2025-09-29, version 5.3.2* MUCHAS GRACIAS POR HACER EL APP!! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
