ReactionTimeTest is the best free Human Benchmark alternative with 30 scientifically-inspired tests to measure your reaction time, click speed, typing speed, memory, aim, and cognitive abilities. All tests run instantly in your browser with no signup, no downloads, and no ads. Your scores are saved locally.
Test your reaction time by clicking when the screen turns green. The average human reaction time is 200-250 milliseconds. Professional gamers and esports athletes score 150-180ms, while Formula 1 drivers react in under 150ms. Our reaction test provides instant results with grading from S to F rank.
How fast can you click? Measure your clicks per second (CPS) with our click speed test. Choose 1-second, 5-second, or 10-second modes. The average CPS is 6-8 clicks per second. Advanced techniques like jitter clicking reach 10-14 CPS, while butterfly clicking can hit 15-20 CPS.
Test your typing speed in words per minute (WPM) with real paragraphs. The average typing speed is 40 WPM. Touch typists average 60-80 WPM, competitive typists reach 120+ WPM, and the world record is over 200 WPM.
Improve your aim for FPS games like Valorant, CS2, Fortnite, and Apex Legends. Click 30 targets as fast as possible. Track your average time per target and improve your mouse control and precision.
Challenge your short-term memory with number memory (remember digits), visual memory (grid patterns), sequence memory (Simon Says), chimp test, word memory, color memory, and location memory. These tests measure your working memory capacity.
Exercise your cognitive skills with mental math (solve equations fast), Stroop test (name colors not words), pattern recognition (find what comes next), quick decision making, word scramble, and speed matching. These tests measure processing speed and executive function.
Screen for color vision deficiency with our Ishihara-style color blind test. Test your hearing range with our frequency hearing test - humans typically hear 20Hz to 20,000Hz, with age-related hearing loss starting around 15,000Hz.
Complete multiple tests and get your estimated Brain Age score. Like Nintendo's Brain Training, your Brain Age is calculated based on reaction speed, memory capacity, and cognitive processing speed across all 30 tests.
Unlike other human benchmark sites, ReactionTimeTest offers 30 tests (not just 5), beautiful themes, comprehensive score tracking, and works offline. Perfect for gamers measuring their reflexes, students testing cognitive abilities, and anyone curious about their brain performance.
