Your body runs on a 24-hour biological clock. Circadian Prime organizes your entire day — workouts, meals, sleep, habits, and recovery — around your local sunrise and sunset.

Every cell in your body contains a molecular clock. These facts are the foundation Circadian Prime is built on.
The human circadian clock runs slightly longer than 24 hours. Morning light exposure resets it daily, keeping you synchronized with the solar cycle.
Dim-light melatonin onset (DLMO) typically occurs ~2 hours after sunset. This is why Circadian Prime sets your bedtime recommendation at sunset +2h.
Getting outside within 30 minutes of sunrise suppresses residual melatonin and anchors your cortisol peak — the single most powerful circadian reset available.
Your brain cycles through focused and diffuse states roughly every 90 minutes. Circadian Prime's schedule builder respects these ultradian windows for work and recovery blocks.
The suprachiasmatic nucleus (SCN) in your hypothalamus receives direct input from retinal ganglion cells containing melanopsin — a photopigment sensitive to short-wavelength (blue) light. Morning sunlight suppresses melatonin and triggers a cortisol pulse. Evening darkness allows DLMO (dim-light melatonin onset) to begin, preparing your body for sleep.
Circadian Prime calculates your local sunrise and sunset every day using your GPS coordinates and uses these as the anchors for every recommendation in the app.
Six core pillars — all real, all working, all organized around your circadian rhythm.
Your daily schedule auto-adjusts to your local sunrise and sunset every single day. Time blocks for workouts, meals, and recovery are anchored to daylight — not an arbitrary 9-to-5.
Bedtime recommendations are calculated from your local sunset — the same signal your brain uses to release melatonin (DLMO). Balanced chronotype target: ~2 hours after sunset.
Log every set, rep, and weight. Rest timer auto-starts after each set with a chime on completion. Personal records are tracked per exercise so you can see real progression.
Log meals with full macro breakdown — protein, carbs, fat, and calories. Build reusable meal templates, plan your week, and generate shopping lists automatically.
Log mood, energy, soreness, and HRV daily. Track habit streaks with visual progress rings. Your recovery score is calculated from real logged data — never fabricated.
Guided breathing, ambient sound sessions, and a personal journal — all logged and tracked. Progress photos, body measurements, and 21 achievement badges mark your journey.
Start in minutes. See the difference in days.
