SplitChey
Expense Tracker & Group Finance App
Challenge
SplitChey needed a production-ready expense tracking and bill splitting platform that could handle real-time group finances, multi-currency support, and seamless settlement flows. The MVP needed to launch fast with a clean, intuitive UI that made splitting bills feel effortless — not like doing accounting homework.
Solution
We built SplitChey as a full-stack Next.js application with real-time balance tracking, intelligent debt simplification, and group management. The platform supports flexible split types (equal, percentage, shares, itemized), multi-currency conversion, and automated settlement optimization that minimizes the number of transfers needed to clear all debts. Receipt scanning and expense categorization were added via AI integration.
