Your circadian clock
Your day hasa biology.
BodyClock reads your circadian clock from a single wake time and answers the question that matters: which phase you're in right now, what it's good for, and when the next one starts. Effort lands where your biology can carry it.

Built to answer one question fast.
Now
The answer, at a glance
Open it and you know: which phase you're in, what it's good for, what to skip, and when the next one starts. That's the whole home screen.
Routines
Eight phases, in your words
Each phase holds a few lines of routine — what you actually do there, written your way. No checkboxes, no streaks, nothing to fall behind on.
Rhythm
The wave you actually live
Check in when you feel like it — energy, one tap. Enough of them and your own curve forms next to the textbook one, drawn from real days.
Yours
Rename it. Reshape it.
Your phases are yours: rename them, reword their voice, nudge when they start. The clock bends to how you actually run, not the average.
The careful part
Science without the false precision.
Circadian rhythms are among the best-established findings in biology. The minute-by-minute hacks sold by productivity culture are not, and BodyClock keeps the two apart. It shows you the evidence, names where interpretation begins, and runs a small experiment so your own pattern can overrule the average.
How we writeNo streaks to keep
Miss a night and nothing breaks. The map reads your rhythm from whatever you log.
A schedule to test
Your plan is a starting guess. You try it against real days and adjust what doesn’t fit.
Room to rest
The afternoon trough is for recovering. When it’s time to rest, the app says so.
Pricing
Free to start. ✦ Pro for the deeper map.
Free is the textbook clock, forever. Pro is the app learning yours — your lived wave, drawn from your own days — for $4.99/mo or $39/yr.

How to reset your circadian rhythm
Circadian entrainment in plain terms: why morning light and a steady wake time reset your body clock, how meals, exercise and caffeine help, and a two-week plan to try it.

Your chronotype is a starting point
Chronotype runs on a continuous scale rather than two boxes: where your body clock prefers to sit on the 24-hour dial, how much of it is genetic, and how to read yours from real days.
