This app is kinda simple...It runs a very heavy stress test for your phone/tablet to see its stability.If your device hangs or reboots or it doesn't respond anymore, that means that is unstable.
To see your CPU USAGE, use an app like URSafe CPU Monitor, because this app doesn't allow you to see cpu usage during the test
It should stop after 2 minutes theorically but it may not work this feature!
THIS APP MAY CAUSE SERIOUS DAMAGES TO YOUR DEVICE, LIKE OVERHEATING AND RANDOM REBOOTS WHILE RUNNING THE TEST!!
I AM NOT RESPONSIBLE OF ANY KIND OF DAMAGE OF YOUR DEVICE!!
