About
Circadia builds an hour-by-hour anti-jet-lag plan from your flight — light exposure, melatonin timing, meals, sleep — from the day before departure to 3 days after landing. Every recommendation is sourced from published circadian research (real phase-response curves, not folk wisdom). No app to install, no signup for the free version.
