Lunch Money

A personal finance and budgeting tool designed for people who earn, spend, and save across multiple currencies. Built as a solo project by developer Jen Yip, the app launched in 2019 and grew through word of mouth and a transparent approach to indie development. It connects to bank accounts, supports manual transaction entry, and handles currency conversions automatically. Lunch Money now generates $34k in monthly recurring revenue on a subscription model, serving users worldwide who need more than a single-currency budgeting solution.
