Draw the perfect circle.
One attempt. One circle. Five seconds.
A daily challenge shared by the world,
scored by the steadiness of your hand alone.
One try. No do-overs.
Trace the circle. Lift your finger. That's your score, locked in for the day. Tomorrow the world gets a new challenge — and so do you.
How it works
Show up at midnight
A new circle drops every 24 hours. Same one for everyone on Earth.
One stroke. No restarts.
Trace it with your finger in one continuous motion. Lift up and you're committed.
Live with the result
0–100% against a mathematical best fit. Share it, brag about it, or quietly try again tomorrow.
See it in action
Saturdays get weird.
Monday through Friday is the daily you know. Saturday is something else. The flagship slot picks one of six new twists — each rewrites how the canvas works without changing the rules of "draw a circle." New in v1.3.
Jitters
The phone shakes in waves while you draw. Hold steady through the bursts.
Eclipse
The guide fades the moment you touch down. Finish the circle from memory.
Mirage
Three identical guides appear. Two are decoys. Pick one and commit.
Echo
Your line lags behind your finger by a variable delay. Anticipate the future.
Tilt
Keep the phone flat. Every degree of tilt costs you score.
Mirror
Your finger is flipped. Aim for the blue guide; your stroke lands on the gold one.
What you get
One shot a day
One scored attempt every 24 hours. No second chances. The whole planet plays the same circle.
Leaderboards
Daily, weekly, all-time. Friends-only if you'd rather not lose to the entire internet.
Streaks worth defending
Show up every day to build the count. Pro grants a freeze for the days life gets in the way.
Practice (judgment-free)
Unlimited tries with zero stakes. No score submitted, no one watching. Works offline.
Live stroke feedback
Your line shifts color as you draw — mint when you're round, warm when you're drifting. Calibrate in real time.
Your circle history
Pro saves every circle you've ever drawn, synced across your devices. Browse and judge past you.
