About
EyeUp is ninety seconds a day: five tiny geometric judgements, each scored out of 100 by how close you land, revealed with an engineer's hairline showing exactly how far off you were. There are no rules to learn — everyone on Earth understands "mark the middle" in one go.
THE FIVE TRIALS • Midpoint — mark the middle of a line • Circle centre — find the centre by eye • Bisect — split an angle in two • Right angle — square the corner • Match length — reproduce a distance
One daily, the same for everyone in the world, flipping at midnight UTC. One lock-in per trial. No retries. A verdict out of 500 — from "Needs a squint." to "A surgeon's eye."
THE CALIBRATION ENGINE EyeUp keeps the honest ledger of your eye: per-skill accuracy, weekly drift, score distributions, personal bests and streaks. Practice as much as you like — practice is tracked separately and never touches the record.
BUILT FOR APPLE PLATFORMS Game Center daily and all-time leaderboards with fourteen achievements. A widget with today's state. "Play today's EyeUp" from Siri and Shortcuts. Your history syncs privately through your own iCloud. Full keyboard play on Mac and iPad — arrow keys nudge in half-unit steps.
Free, complete, and quiet: no ads, no account, no tracking, no purchases. Nothing is collected — your results belong to you.
