Fast, Accurate Screen Diagnostics with Easy Color & Touch Tests

Run quick, reliable checks on display quality and touch performance with a streamlined toolkit designed for clarity and precision. Ideal for users who want to improve device responsiveness, reduce eye strain, or verify screen accuracy. Optimized for everyday testing, professional device checkups, and troubleshooting older phones.

Use intuitive color-related tests (purity, gradients, shades) and touch diagnostics (single-touch, multi-touch) to evaluate screen health in seconds. The Display Info panel shows essential technical data—resolution, pixel density, aspect ratio, and brightness—helping you adjust settings for comfort. Double-tap anytime to exit a test, and check frame rate through two smooth animation tests that reveal real FPS performance. Perfect for quick device setup, hardware comparison, and mobile optimization enthusiasts.

Every test is simple to run: fill the entire screen with blue rectangles to complete the single-touch inspection, and verify multi-touch accuracy with up to ten fingers. Whether you’re troubleshooting touch issues, testing before selling a device, or prepping for high-performance gaming, these tools ensure your display and touch screen respond exactly as they should.
