We did a 10-day road trip with four people and varying budgets. The app told us Alex owed Sam 42 dollars at the end. No arguments, no spreadsheets.

The Challenge

Group trip planning is always a mess of three apps stitched together. Flight details in email. Split costs in a spreadsheet. Actual plans scattered across WhatsApp threads that nobody can search. When plans change mid-trip, half the group does not get the update. And when the trip is over, calculating who owes whom requires a math degree and a lot of patience. Four friends on a 10-day road trip should not need a project management setup to split a gas bill.

What We Built

We built one app that handles all three problems. Shared itineraries update in real-time for every group member. The expense splitter detects categories and offers equal, custom, or percentage splits with built-in settlement logic. Google Places integration lets the group discover and pin locations directly to their schedule. An internal chat keeps trip communication separate from personal messaging apps. And a shared media gallery means nobody has to chase photos across three different social platforms after the trip.
