A guide for your journey. Not a prescription.
Dayvia helps organize sleep, light and caffeine around your itinerary. It uses the flight times, time zones and usual routine you enter to build an estimated plan.
Small steps around a changing day
The plan suggests preparation days, periods for rest, daylight and lower light, and optional caffeine guidance. It covers the outward journey, destination and return. You can read the reason behind an action, mark it complete and change your itinerary.
Know the limits
Dayvia’s timing estimates have not been clinically validated. Travel direction, individual sleep needs, daylight availability and health circumstances can change what is practical or appropriate. No app can promise that you will avoid jet lag.
Put your wellbeing first
The app is for adults. It does not diagnose or treat sleep conditions and does not prescribe medicines or supplements. Follow professional advice for your situation. Do not drive or perform safety-critical tasks when tired. Skip or adjust any suggestion that conflicts with your health or safety.
You stay in control
Location access, notifications and caffeine guidance are optional. You can search for places manually, use a saved plan offline and decide which actions fit your day. Check all flight dates and local times against your booking.
