MinLag
Land on local time.
Add a trip and MinLag builds a personal plan for before, during and after the flight: when to seek or avoid light, how to shift your sleep, caffeine and naps. Free, on iPhone and Apple Watch.
The plan runs on your phone. AI only reads bookings and answers a few set questions.What it does
Add a trip in seconds
Type airports and local times, multi-leg, or paste a booking email and let AI read the flights. You confirm before anything is saved.
A plan that runs on your phone
Works offline, with no account needed for the first trip. Light, sleep, caffeine and naps, plus opt-in melatonin, meals and exercise.
Before, in the air, after
Shift a little before you go, sleep or stay awake on board at the right moments, and adapt fast after landing. Return trips are planned too.
Shaped by Apple Health
Sleep, daylight, heart rate, HRV, steps and wrist temperature personalise your body-clock estimate. Health data stays on your iPhone.
Works around your calendar
Meetings at the destination never get a nap or a dark room scheduled on top of them; the plan re-solves around them.
A morning check-in
Tap how you slept and AI nudges the day, always inside the engine's safe limits. Something changed? Pick it from a list and get a fix.
Always in front of you
Apple Watch, widgets, Live Activity and wake alarms keep the next step visible, even in airplane mode.
Travel together
Share a trip with a companion; they get the same flights with a plan built from their own sleep.
