About
Land ready. Body Clock turns your flight into a day-by-day plan for exactly when to seek light, avoid light, sleep, and (optionally) take melatonin — so your body clock arrives when you do.
START FROM YOUR BOARDING PASS
Import a trip in one tap from an Apple Wallet boarding pass or a flight in your Calendar — no typing, no guesswork. Hundreds of airports recognised.
TRAVELLING? Unlike a generic calculator, Body Clock builds a day-by-day schedule around YOUR trip: origin and destination time zones, real departure and arrival times, your chronotype, and how hard you want to push. Round trips and multi-stop itineraries (country to country to country) are handled end to end — it adjusts you there and guides you all the way back home. It even tells you whether to sleep on the flight. And when the trip doesn't go to plan — a delay, a missed step, a rough night — it rebuilds the rest around where your body clock actually is.
STAYING HOME? No travel required. Tell Body Clock where your sleep is now and where you want it — become an earlier riser, recover from a wrecked weekend, or just steady a consistent schedule — and it builds a gentle day-by-day shift using the same circadian science.
WHY BODY CLOCK
• Grounded in circadian science — light timing around your body-temperature low, the strongest lever you have
• Starts from your boarding pass or calendar, so setup takes seconds
• A clear day-by-day plan, in the right time zone, from before you fly to fully adjusted
• Honest in-flight advice: sleep, stay awake, or just rest
• Chronotype + Easy/Balanced/Maximum modes so it fits casual trips and hardcore schedules alike
• On-device by design: your plan is computed privately on your device — no account required
• Optional Apple Health: reads recent sleep to personalise your plan, plus resting heart rate and HRV so you can watch your body settle (never written or shared)
