NULVE
Coming soon
THE COGNITIVE PERFORMANCE APP
Stop forcing focus. Plan your day around it.
Nulve brings in your sleep, estimates a focus window from when you wake, and tracks your results on four quick focus tests.
HOW IT WORKS
Your day starts the night before.
Nulve builds your day from how you slept and when you woke up. It takes seconds each morning.

SLEEP
Sleep. Nulve scores it.
Apple Health brings in your night. Your Sleep Duration Score counts how long you slept and how often you woke up.
MORNING CHECK-IN
Check in when you wake
Two quick questions: when you went to bed, and when your eyes opened. Your health data fills them in.
FOCUS WINDOW
Get your focus window
Your wake time places today's two focus waves. A short night shortens them, so you plan around the day you really have.
YOUR FOCUS WINDOW
Know which hours to protect.
Nulve places two focus waves each day from your wake time and rhythm. It starts as an estimate. Every test you take builds your own record of how you test across the day.
Built from your wake time, one question.
