How it works
The tool listens for Pointer Events first and falls back to Touch Events when needed. All checks run locally in the browser.
Browser compatibility
Modern Chrome, Edge, Safari, Firefox, Android browsers, and iOS Safari support the core test. Older browsers may report fewer details such as pressure.
Common issues
If a point is not shown, remove screen protectors, clean the screen, test another browser, and check whether the app or browser is blocking touch input.
FAQ
Is my touch data uploaded?
No. The test runs in your browser and does not send touch data anywhere.
Can it test multi-touch?
Yes. Use two or more fingers in the test area to check active touch points.
Why is pressure always zero?
Many phones and browsers do not expose pressure data, so zero can be normal.
Does it work with a mouse or stylus?
Yes. Pointer Events can report mouse, pen, and touch input when the browser supports them.
Can this replace hardware repair testing?
No. It is a quick browser check, not a certified repair diagnostic.
