About this app

Is your screen truly perfect?

Bought a new phone? Or maybe noticed an annoying dot while watching your favorite TV show? PixelPure is a simple yet powerful tool that lets you check the health of your display in seconds.

Dead, stuck, or "lazy" pixels can appear on any screen – from budget models to flagships. Our app helps you detect them before it's too late for a return or warranty repair.

What can PixelPure do?
🎨 Full test palette: Display pure colors (RGB, white, black) to spot even the smallest sub-pixel defects.
☝ Intuitive operation: No unnecessary menus or ads obscuring your view. A single gesture separates you from changing the color. 📱 Support for all screen types: Perfect for LCD, AMOLED, OLED and Retina matrices.
