Jet lag costs you the meetings that matter.
Existing apps are generic. None of them account for your specific schedule, meetings, or the way your body actually works across time zones.
Generic plans don't fit your trip
Off-the-shelf advice ignores your actual flights, layovers, and the specific meeting you can't show up tired to.
Caffeine and naps at the wrong time
Most people guess at coffee timing. Done wrong, it pushes your circadian clock the wrong direction and worsens jet lag.
Delayed flights derail everything
When your connection is delayed by two hours, your whole plan shifts. No existing app replans around that in real time.
Three steps to arriving sharp.
LayOvr takes the complexity of circadian science and turns it into a clear, actionable daily plan.
Enter your trip
Add your flights by flight number, or type them manually. Layovers, multi-leg routes, and multi-city trips all supported.
Set your key moment
Tell LayOvr when you need to be at your sharpest: a board meeting, sales pitch, or keynote. The plan builds backward from that moment.
Follow your plan
Get day-by-day guidance on when to sleep, nap, avoid light, get light, drink coffee, and cut off caffeine. Notifications keep you on track.
Built for the road warrior.
LayOvr combines peer-reviewed chronobiology with practical travel experience: offline-first, privacy-first.
Offline circadian engine
The two-process sleep model (Process S + C) runs entirely on-device in Swift. Airplane mode is the use case. No server required for your plan.
Meeting-anchored optimization
Name the moment you need to peak. LayOvr reverse-engineers your entire circadian schedule to maximise alertness at that exact time.
Live flight lookup & delay re-plan
Search by flight number. When your connection is delayed, LayOvr replans your entire circadian schedule around the new timing.
HealthKit personalization
Read-only access to your sleep history and HRV automatically derives your chronotype and tightens the model over time. No watch required.
Lounge & layover intelligence
Database of 50+ business lounges with terminal wayfinding. Layover blocks get strategic nap suggestions and lounge-specific guidance.
Multi-leg & multi-city trips
Full itinerary support: CPH → DXB → PEK with a layover, or a four-city tour. The engine handles complex routes cleanly.
