12 BRAIN TESTS ▸ REACTION TIME — Tap as fast as you can when the screen turns green. Average over 5 rounds. ▸ SEQUENCE MEMORY — Watch the pattern, repeat it back.

Precision meets speed. ▸ STROOP TEST — The word says "Blue" but it's painted red. Tap the color, not the word. ▸ CHIMP TEST — Numbers appear, then hide. Tap them in order. Can you beat a chimp? ▸ TYPING SPEED — Type the sentence as fast and accurately as you can. Measured in WPM. ▸ VISUAL MEMORY — Tiles flash on a grid.
