AASplit – Group trip expense splitter

Log expenses during a trip and settle who owes whom in one tap at the end

Problem

A developer built a group AA expense tracker after a trip where settling up was painful. It reached 4,000 users in four months, proving the demand is real and frequent. Yet most existing options are spreadsheets or clunky group chats, missing travel-specific needs like multi-currency, who fronted the cash, and proportional splitting.

Solution

A dead-simple AA ledger for trips and group dinners: log an expense in seconds with payer and participants, auto-convert currencies, track running balances, and generate a final settlement plan with shareable transfer instructions so no one argues in the group chat.

Users

Young travelers, coworker dinners, roommates, and families on trips

MVP

Create a group and invite members; quick expense entry with amount, currency, payer, and participants; auto currency conversion; real-time balance summary; end-of-trip optimal settlement and shareable card

Revenue

Free basic ledger; paid tier for multi-currency auto rates, Excel export, unlimited groups, and cloud sync; light in-app ads

Why now

Outbound and group travel is recovering, and existing tools are either spreadsheets or rough UX. Mini-program ecosystems let one developer reach users cheaply and grow via word of mouth
