Timing

When you sleep matters as much as how much.

When beats how much

The same 7 hours at midnight and at 4 a.m. are not the same night. Timing changes the ratio of deep to REM, and recovery with it.

What we track

bedtime       consistency matters
midpoint      the biological anchor
window        your personal best
jetlag        drift and correction

Why it matters

Fix your timing before you add hours. It's cheaper, and it works faster.
