How TestM Works

I downloaded the app yesterday an was really impressed with the functionality. It’s easy and intuitive to use and gives you a clear idea of how your phone is performing. There are 3 main steps to running the diagnostic test, firstly the installation, then the four-minute test, and lastly, reviewing the test results.


1. TestM Installation

I have an iPhone so I downloaded the app off Apple’s app store, the app doesn’t need any sign-up details and immediately launches into a helpful tutorial guiding you through how to use the app and sharing some of the most important features.

Your report is then made available, highlighting any problem areas. It picks up the type of phone that you have (currently the app supports over 6500 devices). The app then allows you to email the report to a potential phone buyer or keep as a backup for yourself.

It allows you to run a full hardware diagnostic check on all components on your phone within 5 minutes, by guiding you through a series of tests on your phone hardware.

The test covers the following 6 areas, 22 checks in total:

You can verify if a phone is stolen or not, using the IMEI check on the TestM app as well as checking if the smart device is unlocked and ready for use in your country of choice while also checking for phone repairers near you.

  • Phone first aid

I love the peace of mind that I’ve tested my phone and I know that everything is working as it should. It’s great to have the option of sending the report through as a value-add when I want to sell the phone.
