"That looks easy." Then the reveal shows how far off you actually were. Perception Lab is a benchmark for the senses you never think about — how accurately you judge speed, distance, timing, and change. 46 micro-tests, most under 25 seconds, each measuring one specific thing in real units: milliseconds, degrees, percent. SIX DIMENSIONS, 46 TESTS • Motion & Physics (8) — Speed Copy, Trajectory Guess, Occluded Motion Track, Collision Prediction, Motion Coherence • Space & Geometry (9) — Angle Snap, Distance Recreate, Center Finder, Area Illusion, Mental Rotation • Time & Rhythm (6) — 10-Second Sense, Tempo Match, Reaction Time, Double-Tap Precision, Two-Interval Compare • Focus & Inhibition (7) — Go/No-Go, Change Blindness, Target Tracking, Stroop Speed, Aim Trainer, Symbol Coding • Memory (10) — Sequence Memory, Visual Memory, Chimp Test, Spatial N-Back, Number Memory, Instruction Trap • Calibration & Bias (6) — Percent Estimation, Dot Count, Müller-Lyer Match, Hue Order, Typing Prediction SIX WAYS TO PLAY Today's Run — five tests, seeded from the date. Everyone gets the same set, so streaks and comparisons are fair. Quick Run — a random five when you have two minutes. Practice — pick any test, set the difficulty, drill it until it clicks. Marathon — endless and escalating. Stop when you break. Boss Run — eight rounds on one test, difficulty climbing from 2 to 9, with a single free retry at the halfway mark. Ghost Duel — replay a past run at its original seed and race your own recorded scores. Identical stimulus, no excuses. WHAT YOU LEARN ABOUT YOURSELF Every result feeds a Perception Score and six trait tracks. Over time the app surfaces your systematic biases — that you always tap early, or consistently underestimate distance, or lose accuracy the moment something distracting appears. Those aren't random errors. They're yours, and they're measurable. • A bias profile built from your own error patterns • A 7-day Bias Training Plan aimed at your weakest trait • Weekly recap with 7-day and 30-day trends • 25 achievements, plus trait medals for mastering an entire category • Daily Twist modifiers that bend the rules once you've earned them BUILT TO BE FAIR Deterministic scoring — same seed, same test, every time. Difficulty ramps gradually rather than spiking. Every test reveals the true answer next to yours, in the unit that actually matters. No arcade points, no fake precision, no randomness dressed up as difficulty. OFFLINE AND PRIVATE No accounts. No sign-in. No server. Every test, score, and stat runs on your device and stays there — we have no way to read it. Play on a plane, underground, anywhere. Accessibility: left-handed and one-handed modes, reduce motion, larger text, and independent control over sound and haptics.
