Aim practice online, for any mouse shooter

Aim practice trains a few separate skills, and each can be measured. Flicking is one fast move to a target and a click. Tracking is holding the crosshair on something that moves. Precision is the small correction and the click at the end of a flick. Weakness in one does not tell you much about the others.

Flicks get harder in a known way. Fitts's law scores a movement in bits: difficulty = log2(distance ÷ width + 1). A 30° flick to a 1° target is log2(31), or 4.95 bits. A 5° flick to the same target is log2(6), or 2.58 bits, so the long flick is nearly twice as hard. That is why a routine should mix distances rather than repeat one.

Pick one turn distance and leave it alone. Somewhere from 40 to 50 cm of mouse travel for a full 360° turn is a normal place to start. The average pro needs about 45 cm in Valorant and 47 cm in Counter-Strike 2, per prosettings.net, and AimKata's default of 0.35 at 800 DPI is 46.7 cm.

To work it out in any game, use 360 ÷ (yaw × sensitivity × DPI) × 2.54, where yaw is the degrees that game turns per mouse count at sensitivity 1: 0.07 in Valorant, 0.022 in Counter-Strike 2 and Apex Legends, 0.0066 in Overwatch 2. If you already play one of those, Settings converts your sensitivity to the same turn distance.

For DPI, pick 400 or 800 and stop thinking about it. Around 90% of Valorant pros use one of those two, and about 94% of Counter-Strike 2 pros do.

Prefer short sessions on many days over one long session a week. Motor skills are generally learned better with rest between practice. In a 2015 study of 30 adults on a reaction-time task, spacing practice 12 hours apart improved reaction times more than massed practice, though accuracy did not differ and retention was not measured. It is one small study of a different task, and we found no aim-specific figure, so ten minutes most days is a reasonable reading of it, not a law.

Compare the same drill at the same difficulty on the same sensitivity, and never judge a single run. Aim-trainer scores are repeatable enough to compare: in a 2024 pilot study of 10 esports players, intraclass correlations for KovaaK's scores ran from 0.947 to 0.995. AimKata's Stats screen compares your last five runs of a drill with the five before, once you have six. Change your sensitivity and the comparison stops meaning much, which is one more reason to leave it alone.

The tracker page defines every number AimKata records.

For learning the skill, yes, with limits worth knowing. In Chrome and Edge, AimKata reads raw mouse movement through Pointer Lock with unadjusted movement, so Windows pointer acceleration stays out of the way. In other browsers, turn off Enhance pointer precision yourself. Drills play fullscreen.

An installed trainer has fewer layers between it and your mouse, and we have not measured AimKata's input delay against one. Drills need WebGL2, a mouse and a keyboard, so a phone or a trackpad will not do. AimKata is also built around Valorant, so its field of view, guns and bots are that game's. For a wider library, here is how it compares with the installed trainers.
