ReflexJet - Brain Benchmark

How fast is your brain? Find out.

ReflexJet measures your cognitive abilities across 12 scientific brain tests — reaction time, memory, speed, focus and pattern recognition. Get your Brain Score (0-100), climb the tier system, and see how you compare to the world.

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. Simon-says on a 3x3 grid.
▸ NUMBER MEMORY — Memorize a growing number, then type it from memory.
▸ AIM TRAINER — Hit 30 targets as fast as possible. 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. Remember which ones lit up.
▸ VERBAL MEMORY — Words appear one by one. Have you seen this word before?
▸ GO / NO-GO — Tap green circles, ignore red ones. Speed ramps up. Don't slip.
▸ TRAIL MAKING — Numbers scattered on screen. Tap 1 through 25 in order, fast.
▸ SPEED MATCH — Two symbols flash. Same or different? You have 3 seconds.
