Vibration test does not work, and there isn’t a feature to see the battery’s cycle count or health.

I see your video and decided to give it a try and it works very well. I support your work and love your videos!

I actually give it 4.5 stars, not 4 stars. The only reason why I give it 4.5 stars is because I have to pay a $1 for it. I don’t mind, but please make it free and refund the people who bought it for $1.

This test app will go a long way for any iOS device I purchase. Vary detailed and in depth. Well worth the $0.99!

I just bought a new iPhone 16 Pro Max and when I run the audio test no sound comes out of the speaker and the test fails. But the speakers work fine.

This app is a great tool for diagnosing my own iOS and iPadOS devices. I consider it almost perfect, because there’s two issues that should be fixed. The first issue is the light sensor test. Even with the automatic brightness setting active, this test can’t get results. It’s the only feature in the app right now that isn’t working properly. The other issue is that there’s a missing feature that would definitely be useful if added. If you add a battery aging test to this app, it will be a lot more useful. Those are my only complaints. If those issues were fixed, this app would really be perfect.

This a does the job but it’s not even accessible for those with low vision I have my font size at 190 to 310 and the text increase but when you try to use the app to run a test like touch screen test you can’t even push the start button without having to decrease the font size yes this app does work with voiceover but to use voiceover you have to decreased your font size for the app so if you can make this more accessible optimized for the iPhone cs max and for other iPhones I’ll operate it thanks

This app is very useful and testing all sorts of different devices. I love it. I do wish there was a battery test or battery health identifier. Only reason I gave it a 4 star. I’d love to know the health of my iPads battery. Future update?

Hugh I like your videos and this app but I'd think you'd have support for devices older than iOS 11. I'd buy a mac version if you made one

It seems to be a good app to test all the iPhone functions. I think my digitizer is broken and has ghost tapping up at the top of the screen and testing the touch screen functionality there’s no way for me to give it a fail for that specific test. Other than that, it seems pretty good so far! Also, i’ve been watching you videos for 5+ years and have bought from your online store!
