Просто ужас! ### 2/5 — Significant drain on my iPhone battery *2023-09-05, version 3.13.6* Not sure what’s up, but having Nut app run in the background contributed to a 20% drain on my battery for the last 10 days, which is more than 3x the runner up, Google Chrome app, everything else was sub 5%, and it shared over 10 days the app was running behind the scenes for 112hr but only on screen for less than 1hr, so I’ll try closing it when I’m not using it, but that is a significant usability issue for the app. ### 2/5 — 共有できない *2023-07-24, version 3.13.6* 子供に持たせたくて夫婦でデバイス共有したいのに全くわからん。私のアプリからBluetooth切るとデバイスいなくなるし、どうしたら良いか教えてくれ〜 ### 3/5 — App keeps Freezing *2023-05-26, version 3.13.4* Works fine only if I quit the app and re-open. Otherwise the App is frozen anytime I need to find my item! Force quitting app is getting annoying I been doing that for about 1 year! iPhone 12pro & App updated newest versions. ### 4/5 — Difficult to get another phone to help find it *2023-05-01, version 3.13.4* Works okay with pairing and using with one primary phone. However it’s a nightmare trying to get your spare phone to pair with it by “sharing” and thereby help find a lost tracker. Got the tracker to show on my spare phone after much trial and error but it never detects it even if right close to it. ### 2/5 — 説明書が分かりにくい *2023-04-02, version 3.13.4* 日本語がわかりにくい。使いこなしが難しお。 ### 4/5 — แบตใกล้หมดแต่ไม่มีการแจ้งเตือน *2023-03-12, version 3.13.4* ปกติจะใส่ไว้กับปลอกคอแมว เวลาแบตใกล้หมดในแอพจะเตือนตลอดแต่ครั้งนี้ไม่เตือน หน้าจอที่โชว์ว่าแบตเตอรี่เหลือเท่าไหร่อยากให้โชว์เป็นเปอร์เซ็นต์เหมือนเวอร์ชั่นเก่าจะดีมากๆค่ะ ### 1/5 — Does not work at all *2023-02-13, version 3.13.4* Immediately ran out of power. I bought it two weeks before moving house and it still shows the location at my old house. I tried to use it a year after purchasing when I lost my keys and it was completely useless. ### 4/5 — Very handy *2023-01-08, version 3.13.4* I was looking for a good alternative to AirTags and this is a great solution in my opinion. It does have its downsides (like only tracking when connected to the phone), however if you don’t wanna spend a ton of money then this is the app for you. ### 4/5 — かつて活躍したが *2023-01-07, version 3.13.4* 久しぶりに起動しました。 スマホとの接続はされており、Nut側からはスマホは鳴らせるのですが、スマホ側から探す事が出来ません。 ずっと「モノ探しモード」になっており、ぐるぐる回っており、「コール」ボタンが出てきません。 どうしたら良いのでしょうか？ ## Most critical reviews (10 lowest-rated) ### 1/5 — nut *2026-07-31, version 3.13.6* when not conected to the internet that phone can then add the nut tracker and pair with it and you dont even get a notification ### 1/5 — Disappointed *2024-12-21, version 3.13.6* The Nut has worked perfectly for a long time. Then suddenly, it won’t ring or make any sound or vibration. It will make a sound when I push the button on the Nut. However, when I try to find the Nut with my iPhone, there is no sound. I have followed the directions that are available in the app. However, I have been unsuccessful in getting the Nut to help me find my keys. ### 1/5 — Funktioniert nicht mehr! *2024-09-08, version 3.13.6* Koppeln klappt noch, aber dann kann man weder das Gerät noch das Handy anfunken! ### 1/5 — Terrible *2024-06-29, version 3.13.6* I log in to the app to see where my wallet is and its been offline for multiple days without telling me. I find my wallet on my own and see that maybe a button was pressed so I mess with it and it reconnects. I open the app a few days later to see where my keys are and lo and behold my keys have now been offline for a few days without any notification. When the app does decide to alert me that my object is 5 feet away from me it is extremely annoying and persistent vs a simple notification. You will only get notified when you leave it behind on purpose or of its a short distance away from you. Every where else you wont know its gone and it wont find it for you. ### 1/5 — ファームウェアで当たり外れあり *2024-02-21, version 3.13.6* 同時に買った二つのファームウェアで新旧があり、旧バージョンのアップデートは何回か試しましたがエラーとなります。 旧バージョンはBluetooth が切れる不具合が出始めると頻発します。そのうち直りますが、完全にハズレ。 古いファームウェアをアップデートしてくれたら満点ですが、当たり外れがあるのは商品として問題ありです。 ### 1/5 — No sound on the device *2024-02-06, version 3.13.6* The device doesn’t make a sound. Hard to find the keys when it does play a sound. ### 1/5 — ファームウェアのアップデート *2023-09-09, version 3.13.6* アプリにファームウェアのアップデートというメニューがあるが、実行するとFind3デバイスの電源が落ちるというバグがあり、永久にアップデート出来ない ### 1/5 — Terrible App *2023-07-09, version 3.13.6* It doesn’t update Time or location. It updates just like Apple ever my few hours. And now that I’ve lost it, I can’t trace it at all. Which makes the tech useless. Like I’m literally trying to use the thing for what it was made to do and it doesn’t work. ### 1/5 — Bad *2023-05-28, version 3.13.4* Can't complete the last step ### 1/5 — Kam *2023-02-14, version 3.13.4* Very bad product because i cant find in a long distance it tell me offline ## Most praised reviews (10 highest-rated) ### 5/5 — These things are a lifesaver *2025-12-23, version 3.13.6* They just work! I love them. I have them on my keys, TV remotes & now one that I can hang from whatever bottle of water I’m drinking at the time. lol ### 5/5 — Устройство *2024-12-25, version 3.13.6* Отличная метка, советую. ### 5/5 — Unheilig *2024-12-19, version 3.13.6* Unheilig ### 5/5 — sehr gut *2024-06-03, version 3.13.6* sehr gut ### 5/5 — Отличное! *2024-04-23, version 3.13.6* Хорошо! ### 5/5 — 使いやすい *2023-10-16, version 3.13.6* 小小さくて^ ### 5/5 — Nut *2023-04-08, version 3.13.4* Very very useful. I have four vehicles. ### 5/5 — 便利です‼︎ *2023-04-02, version 3.13.4* 自転車の鍵を紛失した事をキッカケに購入しました。 ４個を二人で分けて使っています。 テスト成功で安心感爆上がりです！ 電池が長持ちしてくれるといいなぁと期待しています。 ### 5/5 — Keys/Device Locator Tab *2023-02-20, version 3.13.4* A few months now to report they are quite good. Definitely would purchase again. Note: When searching for your keys/item/device have other sources of noise eliminated so to hear the beep. ### 5/5 — Great *2022-10-26, version 3.13.2* Easy to set up & use … great The replacement --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
