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 ### 5/5 — Great Service! *2026-08-09, version 3.3* A must have for your phish MM phones toolbox! ### 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. ### 5/5 — Review *2026-08-05, version 3.3* Good ### 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. ### 5/5 — Seems legit *2026-07-12, version 3.3* Like I said, seems legit ### 1/5 — Really inaccurate *2026-07-08, version 3.3* It’s not real at all ### 2/5 — Annoying ads *2026-07-05* If you don’t pay to remove ads, they pop up with sound at random times. 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 ## Frequently asked questions about Ampere ### What does Ampere Battery Charging Check do?
