About this app

Verify your display health in seconds. Touch Tester PI helps you map unresponsive screen areas, test multi-touch tracking, and locate dead zones with precision. A must-have diagnostic tool for troubleshooting device drops, screen replacements, or second-hand phones.

Using an edge-to-edge testing grid and a live multi-touch tracker, Touch Tester PI provides immediate visual feedback on the condition of your touch screen.
