Aim Trainer is a quick reflex and accuracy test, the kind of warm-up competitive shooters use to sharpen their clicks. You pop 30 targets one at a time while the game times every tap, so you get a clear read on your aim and a best to beat. It plays well on Android or desktop. Aim Trainer is free with no app or download, needs no sign-up, works offline, and saves your best privately on your own device.
Chasing targets trains the loop between spotting something and acting on it: see the target, then land the tap precisely. Regular reps tighten your reaction time and hand-eye coordination.
