Garbage app

Unless if I am doing something utterly wrong, this app does not measure anything at all. I understand the limitation with iOS not supplying info, and that the app has to use calculations to estimate (I accept this), however every single charger and cables reports the same 9-11W charging range. At the end of the test, some show 21W, some others 10.2 (or something similar, doesn’t matter it seems), but sometimes for the same charger and brick. Not sure how the charger reads 9-11W fluctuating the whole test, than 21W after. All tests are beneath 60% battery charger, well beneath the 80%. You would be better off timing the percentage change manually than trusting this app, since it doesn’t even explain the discrepancies. And yes I got the paid Ampere 4 app. No support forum anywhere online. So if you are looking to sort through your bag of old cables me charges, you’d be better off just calculating how many minutes per percentage increase your battery gets manually. Otherwise this test app is more confusing than helpful.

this amp does not do real power, voltage and current monitoring, just does an estimate

Not working if you have IOS 17+ it’s just rubbish!

Takes to long to get the test started and then it takes around 20-25 minutes to complete a test that will show a wrong value.

Learn to Develop an App

Stop selling your poor developments if they can’t work efficiently. It’s not right to be ripping people off. And the app has no real features. I rather deal with the adds than to deal with the lies this app provides.

Fake test data?

I doubt the test data. Even after changing the cable and testing under different conditions, I still got almost the same results. This is surprising because I know the performance of the faulty cable was not good.

Hello. Did you go all the way with the test, or judged by the preliminary result, visible immediately? You will have to let system to test it for 15-30 minutes per test to see correct data. Regards, Andre

This Application doesn’t work well, it shows me the same 10-12W charging when I charge by regular 2A charger and by fast charger 40W. It doesn’t its money.

So ein Quatsch, Das 17er lädt locker in der Hälfte der Zeit auf als mein Firmen 15er.

Alleine für diese Antwort/Ausrede würde ich den einen Stern auch noch wegnehmen!!

Vielen Dank für Ihr Feedback. Diese App basiert auf den Daten, die das Apple-Batteriesystem liefert – in diesem Fall also darauf, wie viel Strom Ihre Ladegeräte der Batterie tatsächlich zuführen konnten. Sie können zwar leistungsstarke und teure Ladegeräte verwenden, aber die Apple-Hardware begrenzt die eingehende Energie gemäß ihrer eigenen Algorithmen, um den Akku nicht zu beschädigen. Ich sehe es so: Unsere 2-Euro-App hat für Sie gerade herausgefunden, dass Sie kein Vermögen für extrem leistungsstarke Ladegeräte ausgeben müssen, wenn Sie ausschließlich Ihr iPhone laden möchten, da das Gerät die Stromzufuhr auf Hardware-Ebene auf sichere Werte drosselt. Falls Sie dies weiter besprechen möchten, können Sie uns gerne eine E-Mail an support@criosoft.com schreiben. Wir finden jedoch, dass wir eigentlich ein paar Sterne mehr verdient hätten :) Beste Grüße, Andre

Why sell it if it doesn’t work for iOS 26?

So you download the app, it’s positioned on the store as being compatible with the current operating system, you agree to purchase the app, and the first thing you’re greeted with is “yeah so it stopped working with iOS 16, got worse with 26, and barely works now, thanks for your money”.

It’s extremely difficult to get a reading on a Qi2 charger. Good luck with a Qi1 charger. No way. It took 1 hr and 12 minutes on my Qi2 charger.

It’s a bummer that Apple doesn’t tell us how powerful a charger is. This app is not a perfect estimate but it’s the best we have

Bonjour. On a complètement repensé l'appli, elle est encore mieux maintenant et on espère vraiment qu'elle te plaira ! Télécharge la dernière version sur l'App Store et dis-nous ce que tu en penses ! Merci ! Andre

De verdad súper lenta, poco confiable. A veces da un resultado a veces otro. Compré la versión premium y esta igual de mala que la normal.

Does not work on iPhone as advertised

Just bought this to test charger and cable that seems to be slow. Have an iPhone and as soon as you open app you are warned app now longer works as expected and have to accept disclaimer to proceed (which I did not). Apparently feature app uses for most functionality are not available on modern versions of iOS so does not operate at all as you’d expect from screenshots.

Doesn’t give rate of charge

While this app has several effective functions, I bought it to see the rate of battery charging. It doesn’t do that.
