CheckReaction — Free Cognitive Tests
Measure your reaction, aim, typing, memory — no signup
Most reaction time tests are bloated with ads or require signup. CheckReaction gives you instant access to 5 cognitive tests — reaction time, aim trainer, typing speed, sequence memory, and number memory — plus 17 free arcade games.
I got tired of reaction time test sites that were either full of ads or didn't work on mobile. So I built my own — 4.5KB of vanilla JS, no dependencies.
What surprised me: the keyword "reaction time game" has a KD of 4.8 on Google. The #2 result is a 8-month-old site with DR 0 and terrible UX. There's so much low-hanging fruit in the tool website space if you just build something better than what exists.
Would love feedback on the UI and test accuracy. What other cognitive tests would you want to see?
