It was good app but now they killed it, removing ### 2/5 — 以前は良かった *2025-03-01, version 8.1* なんでセンサー画面なくなっちゃったの？？？ ### 2/5 — 日本語設定がほしいのと拒否設定 *2025-01-09, version 8.1* iPhoneを使用していますが、パソコンとbluetoothで繋ごうとしたときに、なりすましのスマホが接続していることに気がつきました。 誰なのかわからないので、お隣さんか、家族？ パソコン名を変更したり、iPhone名を変更したりして試したのですが、変更するとしばらく接続できなくなるため、これをインストール。 パソコン自体が購入時から乗っ取られてる可能性は高いのですが、スマホも。 一応、逆らえないとしても、自分でなんとかしたかったのでこれをインストール。すると、全く知らないデバイスが何台か、出てきました。怖すぎ！ できたら、そのデバイスを接続拒否したいので、拒否設定を作って欲しい。じゃないと意味ないじゃん。と思います。 私のiPhoneと同じ名前にしているヤツを排除したい。まじで犯罪なのに。 ### 2/5 — Can’t see ID of beacons in Nearby Screen *2024-12-19, version 7.0* Can’t see ID of beacons in Nearby Screen ### 3/5 — ビーコンアドバタイズが正常に機能しない *2024-11-18, version 7.0* 開発中アプリのiBeacon機能確認に使用しました。 このアプリから発信したビーコンを受信すると、メジャーとマイナーの値がめちゃくちゃになります(設定値によらず)。例えば両方0に設定したとしても受信した値はランダムな値になります。 ### 2/5 — Crash on attempt creating new ibeacon *2024-05-31, version 7.0* Every time I am trying to add new ibeacon and save it, the app crashes on iPhone 11 pro, iOS 17.5.1 ### 1/5 — It doesn’t work - simple! *2024-03-03, version 7.0* Downloaded this to try it. Adverts made it unusable, so I paid £3.99 to upgrade, and it is still useless, but without ads. Several “unknown” reports shown as being at varying distances which keep changing from say, 0.8m to 6.0m without my moving. Other known devices (all iOS) just not detected, or also apparently changing location as I watch. Something is seriously wrong. (Still, it cost less than the price of a beer.) ### 2/5 — iPadでは動作しない *2024-02-18, version 7.0* iPhoneではBluetooth機器を検出しますが、 iPadでは一つも検出しません。 ### 2/5 — Missing Critical Information , horrid UX *2023-11-03, version 6.0* Does not show Device ID / MAC. Range scanner is ok but useless, can't tell which device is which in that view, only shows 2 letters of the name and its RSSI. History doesn't use filter. iOS confirmation flash hides menu button, have to wait for flash to go away. ### 1/5 — nefarious behavior *2023-09-07, version 6.0* Experiencing behavior circumventing iOS settings pertaining to the app’s permissions. Will followup with what behaviors I find after analyzing the network traffic ,fuzzing and every behavior I can enumerate with Ghydra for this app Apple is proving to be incompetent vetting iapp store submissions. ## Most critical reviews (10 lowest-rated) ### 1/5 — Unclear *2025-11-13, version 8.4* Search is not available as option. Filtering doesn’t work. But ads banner shown once app launched. Deleted ### 1/5 — INSANE trackers *2025-09-18, version 8.2* The app is showing a cookie consent banner which has about a THOUSAND partners watching what you’re doing in the apps. It would take almost a hour to disable the tracking. This app shouldn’t be allowed on the App Store. ### 1/5 — Verunreinigt mit Konsumerfunktionen *2025-07-27, version 8.1* Verunreinigt mit Konsumerfunktionen ### 1/5 — Not happy *2025-06-22* Charged me $20 when it said it was free!! Not happy!!!!!!!! I had deleted the app straight away and never signed up for a trial! What a joke! ### 1/5 — Perché deve localizzarmi *2025-02-23, version 8.1* Se non abilito la localizzazione non ti permette di usarla!!!!! Ma stiamo scherzando???? Cosa mi devi localizzare???? ### 1/5 — But fixes and enhancements *2025-01-13, version 8.1* Adding a monthly subscription and ads to the app is hardly an enhancement. ### 1/5 — 4.0 is garbage *2025-01-12* The old version was great. New 4.0 buggy and filled with adds now. Alias does not work any more and writes the name to an entirely different device. Device get grayed now and won’t even let you click on them. As the saying goes if it ain’t broke don’t fix it. ### 1/5 — Ohne Standortfreigabe nicht mehr benutzbar, *2025-01-04, version 8.0* damit stößt die App in der EU gegen die Datenschutzgrundverordnung. ### 1/5 — Can’t remove this app *2024-08-30, version 7.0* Don’t want it and I can’t remove it from my iPhone! Help! ### 1/5 — 使うならAndroid版 *2024-08-02, version 7.0* iOS版は日本語表示に切り替えられないうえにデバイス一覧が簡素すぎる。 その一方で iPhone のほうが受信性能が良いためか無駄にたくさんのデバイスが表示されとても使いづらい。 Android版なら一覧にハードウェアアドレスや推定距離も出るので目的のデバイスを見つけやすい。 iPhoneユーザーは他のアプリを探す方がいい。 ## Most praised reviews (10 highest-rated) ### 5/5 — Good *2024-12-11, version 7.0* Very impressed works very well unlike others ### 5/5 — Good at what it says it does *2024-07-22* I tried out a few apps like this one, but deleted the others because this one functioned the most like its description. ### 5/5 — Great tool *2024-07-17* Just bought a wi-fi enabled pool vac…proved the wi-fi was not broadcasting and I wasn’t an idiot. Manufacturer did not argue and sent the replacement power supply. ### 5/5 — Awesome App *2024-07-08, version 7.0* I use it regularly to debug my bluetooth during the development ### 5/5 — Bluetooth *2024-02-23, version 7.0* Great Help! ### 5/5 — Percise *2023-08-18, version 6.0* As described, picks up as fast as an airplane. Someone please figure out and share the code to disable or incapacitate their transmissions. ### 5/5 — 都市伝説関係ないでしょ *2023-08-14, version 6.0* 自宅で起動したら15個の○が検出された。 でも考えたらスマホ5台・PC・ワイヤレスイヤホン2x2・任天堂Switch・コントローラー4個で15個だ。 外で使ったとして、人が多いところだとスマホやワイヤレス機器がたくさん検出されるのは当たり前ってだけだよね ### 5/5 — Me eh encantado el viaje con el mono patín ecléctico *2023-08-03, version 6.0* Me encanta ### 5/5 — Great App *2023-07-07* I am able to connect my first generation Apple Pencil to my new iPad Air, so I love that this app has saved me some money from having to purchase a new one. ### 5/5 — 1A App! Perfekt *2023-05-24, version 6.0* Die App ist echt super! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
