The app requires you leave it on during the charging cycle for several minutes. During that time you will hear a loud annoying soundtrack unless you have turned down your volume **Developer response:** Sorry for the bad ads experience. Its unfortunately not in our hands to control. We can't turn the sound off for these. Regards, Andre. ### 2/5 — Legitimate Interest? *2026-06-21* Update: In the very very very long list of Vendor Preferences each of a lot of Legitimate Interest switches has to be turned off manually! There is no global No! switch for it! Not useful anymore because of system limitations. It’s not the fault of the developers, neither the app deserves stars for something it cannot deliver. **Developer response:** Hello. We completely redesigned the app. Please give it a try now. Hope, you will like the changes! Regards, Andre ### 1/5 — Update v3.0 crashes *2026-03-12, version 3.0* This update does not open just crashes. iPhone 16 max pro iOS 26.3.1 ### 1/5 — Demora longa com propagandas *2026-03-11* Tu fica 20/30min na frente da tela esperando o teste para saber se o cabo ou carregador está bom, e quando finalmente chega no. Final, dá uma propaganda e o teste reinicia **Developer response:** Olá! Nós reformulamos o aplicativo por completo. Por favor, dê uma olhada agora. Espero que você goste das novidades! Um abraço, Andre ### 1/5 — なんか怖い *2026-03-07* 刺した瞬間に料金とか書いてるし翻訳が怪しい、 後チェックしてる時に広告が流れてそれをやらないために150円で広告削除マークがありました。 他のレビューと同じく計測時間が長くiOSは対応しているはずなのに遅かったです。 とにかくおすすめはできません。 **Developer response:** こんにちは。 アプリを全面的にリニューアルいたしました。 ぜひ新しくなったアプリをお試しください。 今回の変更を気に入っていただけると嬉しいです！ よろしくお願いいたします。 アンドレ ### 1/5 — 広告見せたいだけのクソアプリ *2026-03-06* 広告見せたいだけのクソアプリ **Developer response:** こんにちは。 アプリを全面的にリニューアルいたしました。 ぜひ新しくなったアプリをお試しください。 今回の変更を気に入っていただけると嬉しいです！ よろしくお願いいたします。 アンドレ ### 1/5 — Can’t close ads *2026-03-06, version 2.0.10* While the test is running a full screen ad covers the screen so you can’t see the test results ### 1/5 — Плохо *2026-02-26* Недождался результата теста, ждал 20 мин и недождался **Developer response:** Здравствуйте. Мы полностью переработали приложение. Пожалуйста, попробуйте его прямо сейчас. Надеюсь, вам понравятся изменения! С уважением, Андрей ### 4/5 — Крашит *2026-02-07* IOS 26.1 крашит после при запуске **Developer response:** Здравствуйте. Мы полностью переработали приложение. Пожалуйста, попробуйте его прямо сейчас. Надеюсь, вам понравятся изменения! С уважением, Андрей ### 1/5 — Used to be good , no longer *2026-02-01* The app used to be good now it has sticky adds that lock up the app home making it largely useless…. Recommend avoiding this release of it. **Developer response:** Hello. We completely redesigned the app. Please give it a try now. Hope, you will like the changes! Regards, Andre ### 1/5 — Fake app *2026-01-23* Not work at all **Developer response:** Hello. We completely redesigned the app. Please give it a try now. Hope, you will like the changes!

Você poderia tentar reinstalá-lo para ver se funciona? Estamos trabalhando em uma nova versão que, esperamos, resolva esse e outros problemas. Atenciosamente, Andre. ### 1/5 — Useless *2026-08-18* Useless app **Developer response:** Thank you for your … useful review. Any details? What use were you looking to get from it, where app failed? Andre ### 1/5 — Não funciona mais *2026-08-05* Era um dos melhores aplicativos pra testar a amperagem e velocidade de carregamento do celular, mas agora ele simplesmente não abre. Finaliza logo após clicar no app. Alguém pisou na bola ao fazer alguma correção ou melhoria no app. **Developer response:** Olá. Por favor, tente desinstalá-lo completamente. Se isso não resolver, envie um e-mail para support@criosoft.com e tentaremos ajudar. Atenciosamente, Andre. ### 1/5 — Ads are bad *2026-07-15, version 3.3* This app somehow had an app that took over my screen, tried to call a 877 phone number, and kept failing and retrying. I know it’s not this app that made that intrusive scammy ad but I don’t know that using this app is worth the ads. ### 1/5 — Really inaccurate *2026-07-08, version 3.3* It’s not real at all ### 1/5 — Скам *2026-05-26* Ничего не замеряет **Developer response:** Спасибо за блестящий отзыв. Пожалуйста почитайте инструкцию, подождите пока тест завершится. На Эппл он не замеряет сразу. Надо ждать до 30 минут иногда. Спасибо. Андрей ### 1/5 — What a stupid app. Testing it doesnt take few seconds. *2026-05-23* This is stupid, it took 3 mins to test the charging lol. **Developer response:** It takes more like 30 minutes actually. Apple does not have access to get data quick. But thanks for 1 star. We will pass it to Apple. Regards, Andre ### 1/5 — 誤差大 *2026-05-20* iPhone15proを30w充電可能なアダプターで充電。物理的な電流系では19W程度の表示、このアプリでは何回測っても11Wの表示。誤差多すぎて信用できない。 **Developer response:** こんにちは。いくつか質問させてください。テストが完了するまで（完了には、場合によっては30分近くかかることもあります）しっかりと待たれましたか？ それとも、あくまで初期段階で表示される推定値だけで判断されましたか？ また、アダプターが100Wの出力を供給できたとしても、スマートフォン内部のシステムによって、バッテリーにとって安全な数値へと自動的に充電速度が制限されるため、アダプターの最大出力自体は実際にはあまり重要ではない、という点についてはご存知でしたでしょうか？ まずはテストを最後まで完了させてから、その結果を踏まえて、ぜひレビューを更新していただけますと幸いです。よろしくお願いいたします。Andre ### 1/5 — Некорректно *2026-04-04* Показывает одно и то же значение на разных зарядках **Developer response:** В таком случае, для вашего телефона все они доводят один и тот же заряд. И благодаря нашей программе вы это узнали. Эппл не дает зарядкам доводить до батареи слишком много тока для предотвращения повреждения батареи. Если хотите - напишите нам на support@criosoft.com и мы вам дадим больше деталей по этому вопросу. Спасибо за 1 звезду. Андрей. ### 1/5 — Полное гг *2026-04-01* Ничего оно не мерит , что беспровод что провод один ампераж выдает **Developer response:** Спасибо за пахучий отзыв. Вы дождались до конца теста? Или же основываете свои выводы на приблизительном показателе, который мыпоказываем зразу? Дайте тесту завершится, сравните результаты, и я уверен, что они вам покажут правельные данные. Ждать может придется долго. За это - спасибо Эпплу, который забрала все права доступа у разработчиков относительно батарей. Пишите на andre@criosoft.com, Расскажу как правильно прогонять тест. Спасибо за 1 звезду.

Honestly free, no catch which is surprising. After running 2 tests you will get one short and easy to close ad, then you are good to run another 2 tests. Easy to use, solid simple app functionality for anyone to use. And again **IT DOES EXACTLY WHAT IT CLAIMS TO!!! For free at that. Just can’t say enough about it.. it’s hard to find apps these days that are real, honest and reliable. I was so pleasantly surprised that it motivated me to jump on here and do a review! Lol. Love it!! ### 5/5 — Четко *2026-03-16* Амперы мериет все четко ### 5/5 — Update v3.0 *2026-03-15* Thank you dev for a fast response. I can confirm that what you suggested deleting the app and reinstalling worked Thank you This update does not open just crashes. iPhone 16 max pro iOS 26.3.1 **Developer response:** Please uninstall your app fully first, then install a fresh copy from the store. Regards, Andre ### 5/5 — Excellent app *2025-08-20, version 2.0.10* Great app to view the amperage even with iOS limitations --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
