WASD Trainer

This drill trains the half of keyboard control that usually goes unpractised. Aim trainers are everywhere, but in most shooters the decisive mistake is a movement one — strafing into fire instead of away from it, or fumbling a diagonal while under pressure. W, A, S and D sit under three fingers that need to respond without conscious thought, and that reflex is built by repetition rather than by playing, because a match never gives you movement prompts on demand.

Each round runs twenty prompts. A key or key pair appears, the timer starts, and it stops the moment the correct combination is held. Then the drill waits for you to release everything before the next prompt appears. That pause matters: timing from a neutral hand means every measurement is comparable, and it stops a key held over from the previous prompt satisfying the next one instantly, which would flatter the score without training anything.

There are two difficulty levels. Single keys drill the four cardinal directions in isolation, which is where you should start. Adding diagonals is the harder and more useful setting, because two fingers have to arrive together and the diagonal is the foundation of strafing, peeking around cover, and counter-strafing to stop before a shot.

Read reaction time and accuracy together rather than chasing one of them. A fast wrong key is worse than a slower right one, since in a game it means moving into damage, so a high wrong-key count is a signal to slow down until the mapping is dependable. Speed returns on its own once the correct finger fires automatically. Your best average is stored in your own browser so you can see progress across sessions, and nothing is sent anywhere.
