Cirka is a premium jet lag recovery planner that turns every international flight into a personalised sleep, light, caffeine, and meal plan — calibrated to your direction of travel, time-zone shift, and natural sleep rhythm. Add a flight. Cirka builds your full pre-departure, in-flight, and recovery plan in seconds. Every recommendation is timed to the minute, in the time zone you'll actually be in. ——— DESIGNED FOR TRAVELLERS WHO CROSS TIME ZONES ——— • Pre-departure shifts — your bedtime nudges 30–90 minutes per day toward destination time, starting up to 3 days before you fly • In-flight guidance — when to sleep, when to stay awake, when to drink water, when to skip the meal • Light & dark gating — exact windows to seek sunlight or avoid it, the single most powerful jet lag lever • Caffeine timing — last coffee cut-off based on your destination wake time • Recovery days — 1 to 7 days of declining intervention as your body re-syncs • Multi-leg trips — layovers, long-haul stopovers, return flights all handled in one plan • Flight Mode — full-screen dark in-flight view with destination clock, sleep windows, and one-tap logging ——— BUILT-IN INTEGRATIONS ——— • TripIt import — paste your TripIt feed URL, pick which trips to import • Apple Health — reads your sleep duration to compare planned vs actual • Weather-aware light — uses real WeatherKit forecasts to suggest indoor alternatives on cloudy days • Public holiday detection — adds airport buffer time during national holidays at your origin or destination ——— HOW THE PLAN WORKS ——— Cirka uses a tier-based shift model rooted in circadian biology: • Shifts under 3 hours — minimal intervention • 3 to 5 hours — 1 pre-departure adjustment day • 5 to 7 hours — 2 days • 7+ hours — full 3-day pre-shift Recovery scales similarly. Override at any time if you want a shorter or longer plan. ——— PRIVACY ——— Cirka stores everything on your device. No accounts. No third-party tracking. No analytics SDKs. Health data is read only, never written. Location is used to fetch destination weather, only while the app is open. ——— DISCLAIMER ——— Cirka is a wellness planning tool, not a medical device. Sleep, light, caffeine, melatonin, and fasting suggestions are general wellness guidance, not medical advice. Do not start, stop, or change any medication or sleep protocol based on this app alone.
