Measure your reaction time in milliseconds and train your brain with 10 free cognitive tests — reaction, aim, memory, typing and more. No signup needed.

Wait for green. Click. One number in milliseconds — measured the way sports scientists measure it, then benchmarked against published norms for your age. Most healthy adults land between 230 and 310 ms (average). Below 190 ms is exceptional — typical of esports players and athletes who train reaction speed. Above 350 ms is worth working on. Reaction time peaks in early adulthood and declines gradually as nerve conduction slows. Run the test several times and read your average — not a single lucky click — as your real baseline. Sleep 7–9 hours. Deprivation is the single biggest drag on reaction speed. Practice daily. Even five minutes of a reaction or aim test strengthens the pathway. Cut…from reflexx.uk
