Discover your Biological Prime Time

A sixty second tap test that reveals the hour of day your nervous system is genuinely at its sharpest.

Most leaders schedule their hardest decisions by habit, not biology. This shows you when your brain is actually fastest, so you can protect those hours.

How fast you can tap is a proxy for nervous system alertness. Faster taps mean a sharper, more responsive brain in that moment.
Test at a few different times of day and a pattern emerges: the hours you are wired for deep work, and the hours you are not.
Once you know your prime time, you can defend it. Put your most important decisions, negotiations and creative work there.
It is the same measurement we use inside our six week day design course. Here it is yours for free.

Your Biological Prime Time

Tap as fast as you can

Rest your hand comfortably. When you tap Start, tap the panel as fast as you can until the ten seconds run out. Use the same hand every time so your results compare fairly, and come back at different times of day to build your picture.

Tip: rest your phone on a table and tap with one finger, or use a laptop trackpad. Keyboard users can press the space bar to tap.
