About the Touchpad Test.
ToolCheckup's touchpad test is a free diagnostic that runs entirely in your browser. Move your finger to draw a live trail, tap to count clicks, two-finger scroll to read the deltas, and place several fingers to map multi-touch — so you can see exactly what your trackpad reports without installing anything or sending a byte of data anywhere.
What this tool is for
A flaky trackpad is maddening to diagnose: is the cursor jumping, is a corner dead, is the two-finger scroll dropping, or is the pad just dirty? This page turns every one of those questions into something you can see. The pointer trail exposes jitter and lag, the coverage grid stays dark over spots the pad never registers, the tap counters prove each gesture fires, and an honest capability readout tells you what your specific device and browser actually expose — because pressure, gestures and raw multi-touch vary a lot between Windows Precision pads, Apple Force Touch trackpads, and touchscreens.
Privacy, in one paragraph
Everything runs on your device. The tool reads the same Pointer, wheel and touch events your browser already hands to any web page — there is no recording, no fingerprinting, and nothing uploaded. Your theme and settings live in your browser's local storage and never leave your machine. See the privacy policy for the boring details.

Site FAQ
Is the touchpad test really free?
Yes — the whole tool, no paywall, no sign-up. The site is supported by voluntary donations ("buy me a coffee") and may show unobtrusive ads that never cover or push down the test surface.
Does the test read anything about my trackpad hardware?
No. Browsers don't expose your trackpad's make, model or firmware to a web page. Everything you see — the trail, the contact dots, the scroll deltas, the capability flags — is measured from the ordinary input events your browser delivers, so treat it as an honest picture of what reaches the browser, not a hardware spec sheet.
Why does multi-touch or pressure show as "unavailable" on my laptop?
On most laptop trackpads the operating system swallows raw finger contacts and turns them into gestures — two fingers become a scroll, a pinch becomes zoom — so the browser sees one cursor plus wheel events, not several touch points. Genuine multi-touch dots and analog pressure only surface on touchscreens and a few precision devices. The capability readout says plainly which your device supports rather than pretending.
Which browsers work best?
Any modern browser: Chrome, Edge, Firefox and Safari on desktop, plus mobile browsers for touchscreens. Pointer Events are supported everywhere current, so the trail, tap counters and scroll readout work universally; multi-touch dots depend on your device reporting more than one touch point.
Can I link to or embed this tool?
Linking is always welcome. Embedding the page in an iframe isn't recommended — some browsers restrict pointer capture and event timing inside frames, which can skew the trail and the scroll measurements the tool depends on.
