About NeuroSprint

NeuroSprint is a daily brain benchmark: 3 micro-tests (reaction speed, number memory, sequence memory), about 2 minutes, one composite Brain Score out of 1000. Everyone in the world gets the same challenge each UTC day.

How percentiles work. Percentiles come from real player results for each day. While a day is still calibrating (few players yet), we show an estimate based on published human-performance norms and mark it as such.

Brain Age & grades. Brain Age, letter grades and brain animals are playful mappings of your game score — they are not medical, psychological, or IQ measurements. The Focus grade is derived from the consistency of your five reaction taps.

Privacy.No accounts. Your history and streaks live only in your browser. The only thing sent to the server is an anonymous score bucket used to build each day's distribution.
