Intended to aid you in correcting stuck pixels in your iPhone, iPad, iPod and external screens. This isn't just another "test" that you can find online, this APP uses a logarithm who, at a high frequency, excite pixels and hopefully release their stuck state.

Do you want to know if your screen has Backlight Bleeding? And if so, in which range? Soft? Medium? Hard?

Screens are designed to display rapidly changing images for many years. Running ScreenTest for a reasonable time will not cause damage to your screen. ScreenTest has been used to successfully repair thousands of screens. Other applications and videos which turn the entire screen on and off rapidly cause a significant strain on the power circuitry and could damage your screen. ScreenTest's logarithm ensures that the average power requirement is roughly constant which is safier than other ways.

Just efficient.
