Jet Zzz
A jet lag planner that respects your real life.
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.
Hi PH 👋
I built Jet Zzz because every jet lag tool I tried felt designed for someone else's life — they wanted a login, ignored layovers, and assumed I could move my bedtime by three hours with no consequences.
Jet Zzz starts from the opposite assumption: your life keeps happening, and the plan has to fit around it. You enter your flights (multi-leg, layovers supported), your usual sleep window, the meetings you can't move, and any supplements you're open to. It produces a day-by-day schedule of sleep, light, and caffeine/melatonin timing you can export to .ics or PDF.
The engine is built around one well-documented constant — the body shifts about an hour per day — and treats eastbound and westbound trips differently because the phase response curve is asymmetric.
Privacy: no account, no server-side storage of itineraries, nothing leaves your browser. Free. 9 languages.
Would love your feedback — especially weird itineraries that break the planner. I'll fix them and credit you.
