Touch Response & Multitouch Test
Measure how quickly this browser reacts to your taps, and see how many simultaneous touch points your screen and browser report.
Live touch points
Place multiple fingers on the touch target area below to test multitouch support live. This reads Pointer Events / Touch Events; it cannot detect touch points your OS or browser filters out before they reach the page.
Tap latency test
Tap the circle as soon as it appears. We record the time from your
pointerdown event to the next painted frame, over
10 taps.
Press "Start test" to place the first target.
Note: this is not a true glass-to-photon latency measurement (that requires a high-speed camera pointed at the physical screen). It measures the delay from the browser receiving your input event to the next time this page paints a frame — a rough software-side proxy that is also affected by your browser, OS, and current page performance, not purely your touchscreen hardware.
