Find the sensitivity
you actually aim best at

Measured, not guessed.

Most players copy a pro, or nudge a slider until it feels right. This measures your own aim across a ladder of sensitivities, finds where you actually perform best, and converts that into the number each game wants.

How it works The research behind it

Two measurements

Flicking and tracking are different skills

You are shown targets at a sensitivity you are not told, several times over, at levels spread around your current one. Speed and accuracy both count, and a miss is scored as the slowest possible attempt — so spraying cannot flatter a result.

The results screen: a flick optimum of 10939 counts per 360 degrees and a tracking optimum of 12923, each with a confidence range, and per-game sensitivities below — Two optima, each with the range it is actually confident about — and the per-game numbers underneath.

Why no DPI

Every competitor asks for your DPI. This one has no use for it.

Your mouse reports counts. A game turns counts into degrees. So the sensitivity you need is 360 / (counts per 360 × the game's yaw) — and your DPI is not in that equation anywhere.

Every tool that asks for DPI inherits whatever error is in the number you type. Mouse software rounds it, marketing exaggerates it, and few people have measured it. This app only uses DPI to show you a distance in centimetres, and it works fine without one.

The range

Then practise at the number you just found

Sixteen drills and five playlists, in a room built to look like somewhere rather than nowhere. Flicks near and far, target switching, precision under a clock, and tracking that asks you to hold still rather than keep up.

Progress

Compared against your own past, not a number we invented

Every run records the sensitivity it was played at, because a score only means something next to another taken at the same one. Change your sens and the progress view says so instead of drawing one confident line through it.

A daily set of three drills comes from the date, so it is the same for everyone that day and cannot be rerolled into something easier. Sessions are compared drill by drill — and only over the drills two sessions actually share.

Guesses are labelled as guesses

The last one is the one that costs us something. Where nobody has measured a game's turn rate, the app says so and refuses to invent one. Where your data is too thin to find a peak, it tells you that instead of fitting a curve to noise. The method page sets out exactly what is proven and what is our own extrapolation.
