PixelCheck: Dead Pixel Test
Screen & OLED Burn-in Tester
$0.99 · Designed for iPad. Not verified for macOS.
Buying a used iPhone or iPad? Check the screen first. Test for dead pixels, stuck pixels, touch dead zones, and OLED burn-in — no internet required.
Buying a used iPhone? Just had your screen repaired? PixelCheck gives you four quick tests to verify your display is perfect.
DEAD PIXEL TEST
Cycle through 8 full-screen colors — white, black, red, green, blue, yellow, cyan, and magenta. Dead pixels and stuck pixels stand out immediately against solid colors. Tap to cycle, swipe to go back.
TOUCH SCREEN TEST
Draw across a grid overlay to verify every zone of your touch screen responds. Track your coverage in real time and make sure there are no dead spots.
OLED BURN-IN TEST
A slow-moving gray block and uniform gray screen reveal ghost images, uneven brightness, and burn-in damage on OLED displays. Adjust the gray level to catch subtle issues.
