TripShare Atlas takes the awkward math out of shared spending. Whether it's a weekend trip, a shared flat, a group dinner, or a long vacation, the app keeps every cost transparent and tells everyone exactly who owes whom.

Create a trip, share a 6-character join code through any app, and start adding expenses together in real time. The moment someone logs a cost, every member's balance updates instantly.

WHY YOU'LL LIKE IT

Flexible splitting for every situation
Split any expense four ways — Equal, Exact amounts, Percentages, or Custom shares. Pick who paid, choose who took part, and tag it with a category and a note. The person who paid can always edit or delete their own entry.

Balances that actually make sense
TripShare Atlas shows each person's net position for the trip at a glance — what you're owed and what you owe, always summing to zero. Built-in debt simplification reduces the whole group to the fewest possible payments, so nobody pays back five people when one transfer will do.

Settle up with confirmation
Record a real-world payback and the person receiving the money approves or declines it. Approved settlements are timestamped and saved to the activity log, so the group always keeps a clear, trusted record of what's been paid.

Insight at a glance
Every trip has its own dashboard — total spent, your share, your paid amount, a spending-by-category pie chart, and a per-payer breakdown. A separate cross-trip dashboard rolls up your spending across every trip you're in.
