What is NeuroSprint?
NeuroSprint is a free daily brain benchmark: a 2-minute test of reaction time, number memory and sequence memory. Everyone in the world gets the same seeded challenge each day, so scores are actually comparable — you get a Brain Score, a playful Brain Age, letter grades for each skill, and your percentile among today's players.
No account, no install, no tracking — your history stays in your browser. Share your result as an emoji grid, or send a challenge link and let a friend face the exact same test. New sprint at midnight UTC.
