Aim Trainer
Targets appear; you click them. Simple. But this is the reflex that wins gunfights: not just reacting, but reacting and moving the crosshair onto a spot, fast and clean. Hit 30 targets, then see your average time per target, your best, and your accuracy.
- 30 targets
- Hit them fast and accurately
- Under 400 ms
- An excellent time per target
- Misses count
- A stray click hurts accuracy
The reflex that wins duels
In a shooter, raw reaction speed gets you noticed and aim gets you the kill. The two are different muscles. Reaction is the spark: the instant your brain registers an enemy. Aim is what happens next: snapping the crosshair onto a head-sized box before they do the same to you. This trainer isolates that second part, the find-and-click, and times it honestly.
Because every target sits somewhere new, your score blends three things: how fast you spot the target, how quickly you move to it, and how precisely you land the click. Bigger, closer targets are quick; small, distant ones cost you. That trade-off is Fitts's law, and it is the same maths that decides whether you win a flick in-game.
Fitts's law: why only the ratio matters
Paul Fitts worked this out in 1954, and it has survived seventy years of people trying to break it. The time to hit a target depends on an index of difficulty that combines how far you must travel (D) with how wide the target is (W): ID = log2(D / W + 1), measured in bits.
The predicted times below use 150 ms of fixed overhead plus 120 ms per bit. As with any Fitts fit, those two constants are yours to discover, not universal truths, so watch the ordering rather than the absolute numbers:
| Distance | Target width | D / W | ID | Predicted time |
|---|---|---|---|---|
| 200 px | 64 px | 3.1 | 2.04 bits | 395 ms |
| 200 px | 32 px | 6.3 | 2.86 bits | 493 ms |
| 200 px | 16 px | 12.5 | 3.75 bits | 601 ms |
| 400 px | 32 px | 12.5 | 3.75 bits | 601 ms |
| 400 px | 16 px | 25.0 | 4.70 bits | 714 ms |
| 800 px | 16 px | 50.0 | 5.67 bits | 831 ms |
Compare rows three and four. A 16 px target 200 px away and a 32 px target 400 px away are equally hard, because only the ratio counts. Halving the target size costs you exactly what doubling the distance does. That is why a game's hitbox size matters as much as how far your crosshair has to swing, and why lowering your sensitivity helps: it does not shrink the distance, it makes you land inside W more often.

How to actually improve
- Lower your sensitivity a notch. Most people over-flick. A slightly slower sens trades a little speed for a lot of accuracy.
- Warm up before you play. Thirty targets here costs you under a minute and noticeably wakes up your aim.
- Chase accuracy first, speed second. A 90% accurate run that is slightly slower beats a frantic 60% one in a real game.
Want the pure version without the movement? The classic reaction time test strips it back to a single click. Try both and watch how much the aiming part adds. If you play tactical shooters, the Valorant reaction time test covers what actually decides a duel, including why peeker's advantage beats raw reflexes.
