Click or tap the targets · arrow keys move the crosshair, space fires
This free aim trainer measures how fast and how accurately you can click. A target appears; hit it and the next one pops up somewhere else. You get 30 seconds, and every hit shrinks the targets a little, so a run that starts easy finishes genuinely hard. Your score is the number of targets popped. Alongside it you get accuracy — hits divided by total clicks — and your average time per target in milliseconds, which is the number most people actually want to improve.
Mouse players should rest the wrist and move from the elbow on the big sweeps, then fine-tune with the fingers; one smooth movement beats a wild flick and two corrections. Missing costs you nothing but time, though the accuracy figure is there to stop you spamming clicks. On a phone or tablet, tap the targets directly. On a keyboard the arrow keys move a crosshair and space fires. Your best score is saved in this browser, so you can come back and find out whether your aim is actually improving.
