Jet Zzz turns your flight itinerary, sleep habits, and meetings you can't move into a day-by-day plan for sleep, light, and caffeine — exportable to your calendar.
Multi-leg routes and layovers are handled. Eastbound and westbound trips are scheduled differently because the body shifts asymmetrically. No account, nothing leaves your browser, free, 9 languages.
Built by one person, for travelers who want to arrive adjusted instead of wrecked.
