TripTally
A live group trip planner where one person books dinner and everyone else's itinerary, budget, and reservation updates in the same second.
Friend groups and families coordinating vacations together in real time
- Itinerary edits propagate instantly across all members' phones with diff view
- Shared budget tracker with per-person spend and live settle-up suggestions
- Reservation vault where any member can attach confirmations that everyone can open offline
- AI trip assistant that flags double-bookings and suggests gaps in the day plan
