HappenUpon
Travel Itinerary Planner
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
HappenUpon is the travel planner that keeps every detail of your trip in one place — flights, hotels, restaurants, activities, car rentals, cruises, and more — organized day by day, right in your pocket. Whether you're planning a weekend getaway or a multi-city adventure, HappenUpon gives you one clean, beautiful place to see it all.
Plan every trip, day by day
Create trips and build a complete day-by-day itinerary with ease. Add any type of booking — flights, hotels, car rentals, restaurants, activities, transport connections, cruises, or open-ended notes and journal entries. Everything is presented in a clean timeline so you always know what's happening next, and what's coming after that.
Email Auto-Parse — paste, done
Copy any booking confirmation email and HappenUpon extracts the details automatically using AI. Flight numbers, hotel addresses, confirmation codes, check-in times — pulled out instantly with no manual typing required. Just paste and move on.
Trip Gallery & Postcards
Every photo you attach to a trip item lives in your personal trip gallery, organized by trip. Relive your travels at a glance — or turn any moment into a shareable postcard with a custom message and your choice of layout. Perfect for sending to friends and family while you're on the road.
Secure Vault
Store your passport number, Known Traveler Number (KTN/Global Entry), and airline loyalty program numbers in your device's encrypted Keychain storage. Your sensitive travel credentials are never uploaded to any server — they stay on your device, protected by iOS security.
PDF Export
Share your itinerary with travel companions as a beautifully formatted PDF. Control exactly what's included — hide loyalty numbers and personal details for a clean shareable version that's ready to print or forward.
Backup & Restore
Export any trip as a backup file you can save to iCloud Drive or share anywhere. Import it instantly if you switch devices or need to restore. Your trip data is always in your hands.
