How It Works
No lengthy assessments. No clinical jargon. Just a simple, repeatable test you can do anywhere.

Anytime during your day, run a 6-trial quick check. It takes under a minute and compares against your baseline.
Over time, see how sleep, caffeine, exercise, and stress affect your mental sharpness with detailed trends.
Science-Backed
The PVT is the gold standard in sleep and fatigue research, used by NASA, the military, and universities worldwide.
Performance Levels
After every test, CogniTrack rates your performance relative to your personal baseline.
Faster than 90% of your baseline. You're at peak sharpness.
Within your normal range. Steady and reliable performance.
Noticeably slower. Consider rest, hydration, or a break.
Significantly below baseline. Avoid demanding tasks if possible.
