CognitiveDrill

CognitiveDrill provides fast, accessible laboratory benchmark tests designed to accurately measure reaction time, memory, attention, and input speed. Every test takes under two minutes and uses millisecond-precise timing that discards guesses (<100ms) and evaluates scores using median trials. Unlike typical brain-training platforms, CognitiveDrill makes no exaggerated diagnostic claims or promises to make you smarter—just pure, honest performance metrics benchmarked against real reference distributions. Completely free with zero sign-in required.
