It’s pretty thorough
But... the ads become longer and longer the further through the tests you get. Gets pretty annoying by the end.
Also it’s not clear which tests you have passed and which you still need to do. It indicated my phone had passed all the tests, but as I looked down through the tests I realized there were several tests I had not performed yet.
Finally, the ambient light sensor test is really superficial. What you really want to know is whether or not the phone can successfully dim the screen as ambient light intensity decreases and vice versa. All it does is presumably check to see that the input from the sensor decreases when you place your hand over it.
Regarding the back camera test, I’d like to know how the person running the test would know when their face is fully framed when they have the screen turned around backwards so they can’t see it. That’s a two-person test to be sure.
The instructions for the compass test need to be clearer. While the animation shows how the test should be performed, the text of the instructions doesn’t explain you must first place the phone down on a flat surface, screen side up, and then flip it over, screen side down. So the people who are having trouble with that test are probably doing so because they are reading your instructions :-).
Still, for free, it’s a pretty good app and quite thorough.

Thank you very much for the feedback!
First, we will explain that the advertisements allow us to offer the free application tests.
There is a paid version where there are additional tests and no advertisements.
With regard to the tests, you seem to have started the automatic test and therefore the screen presented you with tests that were not done. Not all tests are still in automatic testing.
For the rear camera test, the application makes a sound when performing the test, so the user can conclude that the test is complete.
We will check the compass check instructions, thank you very much.
We continue to improve and streamline the various application tests.
We'd love to know what type of device you're using.
Thank you very much for the constructive criticism! We'd like to hear from you again.

This app came highly recommended by Kim Komando and most of the users of it, so I installed it. When I opened it, I agreed to allow the thing to access my location when the app was running and to send me push notifications, then I watched a screen that had the app name and a little processing wheel go round and round and round and round and round... and round some more, but nothing else happened. I tried uninstalling and reinstalling, same thing. I tried clearing memory, same thing. I tried clearing memory and turning off the phone for several minutes before trying again. Same thing. Finally I decided to quit wasting my time, uninstalled it, and wrote this review. I have a relatively new iPhone 8 and am using only 26 GB of the 64 GB of storage, and the App Store told me that TestM would run on my phone, but it hasn't. I welcome any suggestions from the developer.

Great app, a must have
Agree with other review, this app is a keeper. Just bought a used iPhone and checked all functionality with this app. The only thing that didn’t pass were the earphones, but I think that is because these are the new connections on the headphones that now have lightning connection instead of the older plug into headphones port type. So that function could use an update from developers but otherwise this app is top knotch! Recommend to all!
