It's clear that the TestM, the development team, cares about their application and their users experience. Their response time to reviews is very good. With that said, the frequency and quantity of ads is astoundingly high. The ads interfere with the testing features and will cause the tests to fail even if the hardware components your testing are known good. It's understandable that ads need to exist within a free service, but it's inexcusable when the ads interfere with the functionality.

Hi Tara We do everything possible to improve the quality of tests in the app. As the advertisements have indicated, we allow the app to be offered for free, soon there will be a change and the amount of advertisements will be reduced so that everyone can enjoy the use and efficiency of the tests. Thank you for understanding, TestM team

App was fine & it did all the test properly. It was very slow in testing & failed at one which is the GPS. Maybe because my phone is 2yrs. dated & it take a few minutes of non-stop GPS connection to get a satellite signal. There are different options as well like nearby repair, trade-in & insurance but this is where the problem lies. Alas, this functions were not useful because, as stated in app, my country isn't supported. Welcome to the 3rd world. I will appreciate if you add a notice to this.

I love this app. The test is so Accurate, Awesome, and Helpful. The only thing that it isn't so accurate is from the category of the sound, the earpiece. During the test, it says that you must listen through your earpiece and hear the 3 numbers from the female-voice AI. After that, the first number was told but it came from the speakers and the other two numbers are haven't told. I tested my phone earpiece by calling my own phone to another phone and it worked properly. Please fix it.
