Sleep math that doesn't assume you sleep at night.
A day-routine engine built on offsets from when you actually wake and go to bed, not fixed clock times — because a schedule that assumes everyone sleeps 11pm to 7am is wrong for a real fraction of the people who need it most.
Offsets, not clock times
The day's structure is built from how long since you woke and how long until you plan to sleep, so a 2pm wake time gets the same logic an 11pm one would.
Sleep debt that still accumulates honestly
Whatever hours your schedule actually allows, the debt term tracks the real gap between what you needed and what you got — it doesn't assume a night-shift schedule is automatically fine.
Water and meal reminders that follow your day, not the clock
Reminders are built from how far into your own waking day you are, not a fixed 9-to-5 assumption.
A coach that reads your actual pattern
Nova reads your logged sleep and wake times as they actually are, not as a template assumes they should be.
What Life OS doesn't try to be
It doesn't give circadian-rhythm medical guidance for shift work — that's a conversation for a doctor, especially for rotating schedules. What it does is stop assuming your day looks like a 9-to-5 when it computes sleep need, water reminders and daily structure.
