The longer answer

Jet lag is less a sleep problem than a timing problem: the fix is getting bright light and darkness at the right hours so your body clock shifts toward destination time, ideally starting before you leave. Timeshifter is the best-known planner: your first plan is free, after that you pay per plan or buy a year of unlimited plans, and it needs a connection only to create or change a plan. StopJetLag takes a more hands-on route, with a travel specialist reviewing a plan built around your actual flights. The two apps of ours give you the same light-timing approach for free. JetLag Quiet asks for your home and destination time zones, flight date and usual wake time, then computes a 3-5 day pre-trip plan with light, dark and optional melatonin windows, exported to your calendar. Lagless builds a 1-4 day light, sleep and meal schedule based on published phase-shifting protocols, covering before, during and after the flight in one calendar export. Ask a doctor before taking melatonin, especially with other medication.

FAQ

Are these jet lag apps free?

Yes. Both JetLag Quiet and Lagless are free with no subscription and no account, unlike Timeshifter, which charges per trip or per year. JetLag Quiet is free forever and Lagless costs $0.

Do they work offline on a plane?

Yes. Both run entirely on-device with no internet required, so you can check your schedule mid-flight or in a basement hotel. This is a key difference from subscription apps that only run when you're online.

What's the difference between JetLag Quiet and Lagless?

JetLag Quiet focuses on a 3-5 day pre-trip light and sleep schedule and lets you save recurring trip templates. Lagless builds a 1-4 day plan that also includes meal timing and covers the in-flight and post-arrival windows, based on the Eastman/Burgess phase-shifting protocols. Both export to Apple Calendar.
