### 3/5 — Бесполезное👎

*2025-09-17*

Покупал чтобы видеть реальную ёмкость аккумулятора.
Оказалось в приложении залоченны все ёмкости моделей iPhone.
Установил Аккум увеличенной ёмкости, видит только заводскую, сколько должно быть с завода в iPhone.
 Разработчики, вы можете исправить? 
Так чтобы ваше приложение видело как 3uTools видит, реальную ёмкость аккумулятора.

### 1/5 — Be warned - not what you’re expecting.

*2025-04-07*

This app intro text is misleading (April ‘25). Apparently Apple have hidden the data needed to get usefully quick data on charge rates, and  you have to measure actual charge time and the app does the maths that you could instead to calculate charge rates.

That’s not the developer’s fault, but they could have chosen to say so before you buy it and find out.

Kinda chapped my cheeks - be aware of this before you spend your money.

### 1/5 — Unusable

*2025-02-27*

This app crashes every single time I try to open it. Absolute waste of money.

### 1/5 — Não funciona

*2025-02-09*

Não funciona no 16 pro

### 3/5 — Doesn’t work very well on iOS 17.2.1.

*2024-01-15*

Update: I got the app working better and thanks Andre for replying to my initial review and attempting a refund. I upped to 3 stars since I’ve been able to perform and record some tests. If the interface said test below 70% charge rather than 90%, it would solve a lot of initial headaches. How is the user supposed to know that if the app doesn’t say? Also, the tests taking >10 to 20 minutes is a long time to wait when you can’t navigate away from the app during the test. Having an estimated countdown timer or a progress bar come up after 2 or so minutes would be helpful to decide whether to continue or abort for another time. Tried on 2 chargers and it didn’t work on either. My wireless charger charged my phone from 70% to 100% with the test running and the app didn’t record anything. I tried another plug-in charger at battery 87% and the battery icon showing charging. The app says the phone must be charging (check) and the battery must be below 90% (check). The test wouldn’t even start.

**Developer response:** Hello.
Please try running tests when your device is discharged below 70% if you are on iOS 17. Apple added several changes that will result in slower tests and need more total discharged percentage of your device battery in order to work. Unfortunately we could not persuade Apple support to reverse this change back in iOS 17. regards, Andre

### 2/5 — Stopped working

*2023-09-30*

Due to iOS17 maybe?? Tests take forever now, results are way off from prior tests with the same gear.

**Developer response:** Update . 10/25/2023.

Hello. Support for iOS 17 was added. 
Please update your app.
Regards,
Andrew

Hello. 
Yes, iOS 17 broke the battery reporting functionality. We opened case with Apple but so far they are not providing any info on when is it going to be fixed if at all. Hope that we will not need to bring it to the media if they will decide not to fix it.
Regards,
Andre

### 5/5 — Lucky

*2022-07-15*

A must to have.

### 1/5 — Gardez vos sous

*2022-01-20*

Ne fonctionne carrément pas

**Developer response:** Merci pour votre avis. Pourriez-vous s'il vous plaît me dire ce que vous entendez par là? Nous avons des instructions de test dans l'application, que vous voudrez peut-être lire avant de tester. Si vous rencontrez toujours un problème avec l'exécution de l'application, n'hésitez pas à m'envoyer un e-mail à support@criosoft.com. Merci. André

### 1/5 — 差评！充电满了没有提示声音？经常弹窗要求客户给软件好评，东西好了会自然给你好评。

*2022-01-18*

差评！充电满了没有提示声音？经常弹窗要求客户给软件好评，东西好了会自然给你好评。

**Developer response:** 谢谢您，对于您的评论。 为了获得声音，您需要打开并激活该应用程序。 在之前的一个 iOS 版本中，Apple 删除了我们用来从后台发出警报的功能。 谢谢！ 问候， 安德烈
