GET THE SHAPE
At midnight, today's shape drops — the same one for everyone, everywhere. One stroke, closed loop.
Every midnight, the whole world gets the same shape. Fit it into your streets, then walk or run the line — your GPS track is the ink. Score it, compare it, share it.
We'll email you when the first shape drops. Founding tracers get early TestFlight access.
The puzzle starts on your couch and ends on your streets. No equipment, no gym, no pace pressure — the line counts, not the speed.
At midnight, today's shape drops — the same one for everyone, everywhere. One stroke, closed loop.
Drag, scale and rotate the shape over your own streets. The app predicts your score before you lace up.
Follow your plan on foot. The magenta line fills in live over the ghost. The wobble stays — it proves you walked it.
Get your score and percentile, then export the card — your line, no map, ready for the group chat.
A cat in Magdeburg curves with the Gründerzeit blocks. The same cat in Chicago goes full right angles. Comparing them is the whole conversation — ranks are percentile-based, so no street grid is a handicap.
Your track is scored against the target with Procrustes superimposition and turning functions. Rotation, scale, mirror — all allowed. The math doesn't care which way your city points.
±5–15 m of receiver jitter makes tiny parking-lot tricks score badly on their own. Bigger drawings, cleaner ink. Speed is capped at human pace — no cars, ever.
Leaderboard entries are re-scored server-side from the raw track. What you see on the boards has been checked, not claimed.
GPS art can reveal where you live — so share cards export without the map by default, start and end points are fuzzed, and your raw track never leaves the phone unless you enter a leaderboard. Scoring runs on-device.
No. Walk, jog, hike, stroll with the dog — anything on foot counts the same. A separate bike category with its own leaderboard comes later.
No. Scoring is calibrated across street-network types, and daily ranks are percentile-based — you compete against the day, not against Venice. A grid cat is its own art style.
The daily shape is free, forever. A Pro tier — shape archive, custom shapes for friends, multi-day mega pieces — funds the servers later.
Yes — GPX upload and Strava import are planned for the web companion, so your usual tracker keeps working.
iOS ships first, Android follows shortly after. Waitlist members get both announcements.
