iTest.

I wish I had this app when I was still doing logic board repair. The only disadvantage is having to purchase the app for every customer phone repair. But for 99 cents it’s a small consumable cost.

I have tested it on my used iPhone XS Max and it works just fine, keep up your good work! I have been watching your videos since Mid 2020. - User from California, United States

While I haven’t tested it thoroughly on different devices just yet, it does have some great tests to ensure functionality of an iOS type device. Would like to note for future improvements is that the screen burn in test still shows the clock and navigation bars and doesn’t appear to be in a full screen type mode. The digitizer test also feels a bit buggy but does work (doesn’t feel too accurate). Overall would recommend for a basic app to troubleshoot devices.
