Let's check your touchscreen.
Touch and drag in the box — each finger shows up. Use several at once to test multi-touch.
Each touch point shows as a circle. Try multiple fingers to see how many your screen tracks.
How the touchscreen test works
The test listens for Pointer Events — the browser's unified language for touch, pen and mouse input. Every finger that lands in the box gets its own numbered dot that follows it in real time, so you can see exactly what your screen is tracking. Lift a finger and the remaining dots renumber; the panel keeps a live count and remembers the most points you managed at once.
Before you even touch anything, the tag above the box shows how many simultaneous touches your device claims to support. Matching that number with real fingers proves multi-touch works end to end — which is exactly what pinch-zoom and two-finger gestures rely on. No permission is needed, and your touches are processed entirely on your device.
What the readings mean
- Touching — how many points are on the screen right now.
- Max points — the most simultaneous touches you've achieved this session. Phones and tablets typically support 10.
Touchscreen test FAQ
How many touch points should my screen support?
Most phones and tablets track 10 simultaneous touches; touchscreen laptops usually do 10 too, though some panels track 5. The tag above the test shows how many points your device claims to support — if fingers stop registering well below that, suspect the digitizer or its driver.
Why does my mouse show up as a touch point?
The test uses Pointer Events, which treat touch, pen and mouse uniformly. On a device with no touchscreen your mouse counts as a single point, so you can still see the tester working — it just can't multi-touch.
Part of the screen doesn't respond — what does that mean?
Drag one finger slowly across the whole box. If the dot freezes or jumps in the same band every time, that area of the digitizer is likely failing. Before blaming hardware, remove any screen protector and wipe off moisture — both cause identical symptoms.
I placed five fingers but only some registered — why?
You may have hit your panel's tracking limit, or palm-rejection logic swallowed a touch it mistook for a resting hand. Spread your fingers apart and press deliberately. If the max never rises above one or two on a phone, that's worth investigating.
Is my touch input recorded or sent anywhere?
No. Touch positions are used only to draw the dots and count points, entirely inside your browser. Nothing is uploaded; only your best score is saved locally on your device.
