One finger · one unbroken stroke

CircleMaster

One dot. One stroke. The screen tells you exactly how round you really are.

There is nothing to learn.

A dot appears. You circle it. A number appears. Everything after that is you arguing with the number.

A single dot on a dark gradient with the prompt: draw a circle around this.
One dot, nothing else on screen. Keep a steady pace — stall and the attempt doesn't count.
The result screen reading XX.XX% after a stroke was stopped part-way.
Lift your finger and the accuracy is already there — unless you stopped half way, in which case there is no number to give you.
The achievements list, mostly locked, with hints next to each entry.
The rest of the list stays locked until you work out what it wants from you.

One rule, several ways to lose sleep over it.

Scored to the decimal

Every stroke is measured against a mathematically perfect circle and handed back as a percentage. No stars, no coins — one number, and it is not flattering.

A leaderboard of strangers

Pick a nickname, post a score, and find out what a steady hand is actually worth once the whole world is holding one.

20+ achievements

Some reward precision. Some reward drawing the thing backwards. A few you will trip over without ever understanding why.

Five languages

English, Russian, Spanish, Dutch and Japanese — because a circle needs no translation but the insults do.
