Touch Screen and Pen Tests
Find dead zones on a touch screen, count touch points and check pen pressure, tilt and touchpad gestures.
Tests
Touch Screen Test
Find dead zones, weak edges and ghost touches on any touch screen.
Touchpad Test
Check taps, clicks, two finger scrolling, pinch zoom and palm rejection on a laptop touchpad.
Multi Touch Test
See how many fingers your screen tracks at once, with each touch point's position and size.
Pen Pressure Test
Check pen pressure, tilt, hover, buttons and line jitter for any stylus or tablet pen.
Drawing Tablet Test
Check pressure, jitter, pen offset and screen coverage on any drawing tablet or pen display.
Touch screens
The touch screen test fills a grid as you swipe, so areas that do not respond stand out, and it watches for ghost touches while your hands are off the screen. The multi touch test shows every finger it sees and the most touches your screen tracks at once.
Pens and tablets
The pen pressure test reads pressure, tilt and hover from a stylus and draws lines that follow your pressure. Artists with a Wacom, Huion or XP-Pen tablet can check the active area, offset and line wobble on the drawing tablet test.
Laptop touchpads
The touchpad test checks scrolling, pinch zoom, taps and clicks, and explains which gestures a browser can see.
Fixing touch problems
If your screen taps by itself, read the ghost touch guide. A laptop touchpad that stops responding is covered in touchpad not working.
