How sharp is your eye?
How sharp is your eye? Keenly is a daily test of perception. Every day the whole world gets the same puzzle: a grid of color tiles where exactly one is a slightly different shade. Find it. Each round the difference shrinks — down to the very edge of human vision (ΔE ≈ 1.0, the just-noticeable-difference). Your result is an acuity score and a global percentile: how fine a difference your eye can actually resolve. Share your spoiler-free grid, keep your streak, and see if you've got an Eagle Eye. • One run a day — same puzzle worldwide • 7 escalating rounds, scored on the finest difference you can detect • Global percentile + ranks, from Warming Up to Eagle Eye • Daily streak, history, and your acuity trend over time • Spoiler-free share grid — compare with friends • Color-blind (CVD) mode — leans on lightness so everyone can play • Premium, editorial design. No clutter, no candy. Keenly+ unlocks unlimited Practice, Hard & Master modes, four color themes (including dark), full history, and removes all ads — one payment, forever.
