Touchscreen Tester

Check in seconds whether your touchscreen detects every area reliably. Great for phones, tablets, and touch laptops.

How the test works

  1. Start the test and move one or multiple fingers slowly across the screen.
  2. Every touched cell turns green.
  3. If dark cells remain, retest that region for possible touch issues.

Live multi-touch

Multiple touch points are displayed at the same time.

Find dead zones

Untouched areas stay dark so problematic regions stand out.

Adjustable grid

Change grid density for a quick overview or a more precise scan.



Example: good and bad result

This is how a typical result can look after a few seconds.

Example of a good touchscreen tester result with high coverage

Good result

Almost all cells are green. Small gaps near edges are normal if you did not touch there.

Example of a bad touchscreen tester result with large untouched areas

Bad result

Large dark areas remain even after repeated touch attempts. This can indicate dead zones.


Tips for accurate results

The test tries to switch to fullscreen so you can check the full display area.
