Why benchmark yourself?
A single score tells you little — the trend is what matters. Reaction time, working memory and motor precision all shift with sleep, caffeine, stress and practice, so running the same short test a few times over a week reveals your real baseline and whether it's improving.
Gamers use these benchmarks to warm up and track reflexes; students and professionals use the memory tests as quick mental exercise. Whatever your reason, your results are stored only in your own browser — nothing is uploaded, and there's no account to create.
