Sandpiper: Jet Lag App

Beat Jet Lag, Arrive Ready.

Free · Designed for iPad. Not verified for macOS.

Sandpiper helps you reduce jet lag for your trip. Enter your flight details and Sandpiper builds a personalized hour-by-hour action plan — telling you exactly when to seek sunlight, avoid light, drink coffee, or take melatonin. The schedule is based on circadian science (the Phase Response Curve), adapted to your natural sleep schedule and the specific timezone shift of your trip. WHAT YOU GET • Light exposure guidance — when to maximize sunlight and when to avoid it • Caffeine timing — when coffee helps your clock shift and when it works against you • Melatonin timing — precisely when to take it for maximum effect • Sleep windows — when your body is ready to sleep in the new timezone • Works for complex itineraries — connecting flights, layovers, multi-city trips, and custom or private flights PRIVACY Sandpiper only collects what it needs: your email address to sign in, and your flight details to build your schedule. No ads. No data sold. LANGUAGES Sandpiper is available in English, 日本語, 한국어, Español, Deutsch, Français, Português, 简体中文, and 繁體中文.
