## What is Sharp Studio?

Sharp Studio is six short focus exercises, designed to be finished in 5 minutes and to feel good to use.

CHIMP TEST
Numbers flash on a grid and vanish. Tap them back in order. Each round adds one more. It is the classic working-memory task, and it gets hard faster than you expect.

SCHULTE GRID
Find 1 to 25 in order, as fast as you can. A grid, a stopwatch and nothing else. The whole difficulty is in not losing your place, and the clock is honest about how that went.

INK TRAP
An arrow points one way and sits on the other side of the screen. Tap the way it points, not the side it is on. Your position tells you one thing and the arrow tells you another, and the gap between them is the whole exercise.

SILENT BEAT
A dot circles to a beat, then the beat stops. Keep tapping it. Nothing marks the time for you but the time you have already kept, which is harder and more interesting than it sounds.

REFLEX RAIN
Drops fall; catch them before they reach the line. You get 3 misses, and the rain gets heavier the longer you last. It ends with the one number everybody thinks they already know about themselves.

BREATHING BLOOM
Follow the bloom through box breathing or 4-7-8. No talking, no music you did not ask for. Just a shape to breathe with.

WHAT YOU GET
- Personal bests for every exercise, kept on your device
- Focus minutes and a daily streak, if that helps you
- A share card worth posting when you beat your best
- Dark by default, because this is an app for concentrating

NO ACCOUNT, NO UPLOAD
Your scores stay on your phone. There is no sign-up, no profile, and nothing to restore.
