Don't lose your first few days of travel to fatigue.

Most travelers try to adapt after they land. JetLagZero helps you adapt during your flight.

Using advanced chronobiology, JetLagZero calculates the perfect in-flight window to shift your internal body clock. By strategically timing your exposure to light, sleep, and caffeine, you can trick your circadian rhythm into aligning with your destination before you even leave the airport.

THE DESTINATION-SHIFT PROTOCOL: • Smart Flight Parsing: simply input your flight details. We handle the complex time-zone math for direct or multi-leg journeys.
• Light & Dark Therapy: Know exactly when to seek light and when to wear a mask. Light is the #1 signal your brain uses to reset its clock. • Caffeine Strategy: Use caffeine as a precision tool. We tell you exactly when to consume it for alertness and when to cut it off to build sleep pressure. • Precision Naps: Calculated sleep windows and "Stay Awake" zones designed to align with your arrival time. • Melatonin Schedule: Exact timing recommendations to chemically signal your brain that it’s time to sleep. • Hydration Tracking: Reminders to combat dry cabin air and keep your body primed for adjustment.

BUILT FOR TRAVELERS: • 100% Offline Mode: No Wi-Fi required. Once your flight is loaded, the entire protocol works in the air. • Push Notifications: Don't watch the clock. We alert you exactly when you need to change your behavior. • Calendar Sync: Export part or your entire custom schedule directly to your device calendar.

PRIVACY FIRST: Your travel data stays on your device. JetLagZero does not collect, store, or transmit your flight details or personal information to the cloud. All calculations are performed locally on your phone.
