Packed with Features
Everything you need to benchmark and train your brain.
Reaction Time
Tap as fast as you can when the screen turns green. 5 rounds, averaged in milliseconds.
Sequence Memory
Simon-says on a 3x3 grid. Remember and repeat increasingly long sequences.
Number Memory
Memorize growing numbers and type them back. How many digits can you hold?
Aim Trainer
Hit 30 randomly placed targets as fast as possible. Tests hand-eye coordination.
Stroop Test
Name the color, not the word. 6 colors, 2 modes, with congruent mixing to trip you up.
Chimp Test
Numbers appear on a grid and hide after your first tap. Tap them in order — are you smarter than a chimp?
Typing Speed
Type a sentence as fast as you can. Character-by-character validation measures your WPM.
Visual Memory

Verbal Memory
Words appear one by one. Have you seen it before? Tap Seen or New. 3 lives.
Go / No-Go
Tap green circles, ignore red ones. Speed ramps up — tests impulse control.
Trail Making
