Measure Your True
Cognitive & Reflex Limits
Test raw reaction speed, working memory span, and spatial motor precision against global human population baselines with instant percentile rankings.
All Benchmark Tests
Pick a test below to start. Each test calculates your score and ranks you against worldwide percentile curves.
Reaction Time
Measure your neuro-motor response time. Click as fast as you can when the red screen turns bright green.
Sequence Memory
Memorize an increasingly complex sequence of illuminated tiles. Repeat the exact pattern without making a mistake.
Aim Trainer
Click 30 randomized targets as quickly and precisely as possible. Evaluates spatial precision and motor twitch response.
Chimp Test
Based on Kyoto University’s primate cognition research. Memorize the position of numbered squares, then click them in ascending order once they are masked.
Verbal Memory
Words appear one at a time. Click "SEEN" if the word has appeared earlier in the test, or "NEW" if this is the first time you are seeing it.
Number Memory
A number flashes briefly on screen. Recall and type the complete number. Each successful round adds another digit.
Visual Memory
A subset of tiles in an expanding grid briefly flip white. Memorize their locations and click all marked tiles after they flip back.
Typing Test
Type a series of common words accurately. Measures words per minute (WPM), net speed, and character-level keystroke accuracy.

Frequently Asked Questions
Everything you need to know about cognitive benchmarks.
What is a good reaction time?
The typical human visual reaction time averages between 215ms and 260ms. Professional esports athletes and fighter pilots often reach between 150ms and 190ms.
Does monitor refresh rate affect scores?
Yes! A standard 60Hz monitor introduces roughly 16.7ms of frame latency, while a 144Hz monitor drops this to 6.9ms, and a 240Hz display down to ~4.1ms. For the purest reflex score, use a high refresh rate monitor and a wired mouse.
Can you train your working memory and reflexes?
While raw physiological nerve conduction speed has genetic baselines, cognitive pipelining, chunking strategies (such as remembering numbers in triads), and motor anticipation can significantly improve test performance over time.
