Three tests.
90 seconds.
One honest score.
A mini cognitive assessment from neuroscience research, built as three fast mini-games. Your reaction time, memory span, and focus score — plus what the numbers mean.
How fast your brain responds.
How much you can hold in mind.
How well you filter distraction.

Questions, answered
Is this a real cognitive test?
Yes. The three tasks — reaction time, digit-span memory, and Stroop interference — are standard paradigms used in cognitive neuroscience research. The scoring is research-grade for tracking your own trends over time, not a clinical diagnostic.
Is my data saved or sold?
Nothing is saved unless you give us an email. Your score lives in your browser's local storage — leave the site and it travels with you. We do not sell any data, ever. Email submission is optional and only used for your weekly focus report.
Is this a medical assessment?
No. This is a self-assessment tool for curious users. Your cognitive performance varies with sleep, hydration, caffeine, stress, and time of day. For persistent cognitive concerns, talk to a clinician.
How accurate are the results?
The individual tests are based on validated research paradigms, but your specific score depends on factors we can't control — device timing, distractions, whether you're tired. For the most reliable reading, take the scan 2-3 times over different days and average.
How do I improve my score?
Sleep is the single biggest lever — most people jump 10-20 points after a full 8-hour night. Hydration, caffeine timing (morning only), and Omega-3 / magnesium support also shift scores over weeks. We recommend retesting monthly to see what's working.
Can I retake it?
Yes. Your first scan is saved as a baseline. Each retake is compared against your baseline so you can see if you're improving. Retest reminders are included if you save your email.
