# Espere > Espere is a free, open-source personal finance app for Android. It tracks personal spending, sets category budgets and splits group expenses with friends, and it works fully offline: everything syncs to the cloud once the phone is back online. Espere does not sell personal or financial data. Espere is built around four things: adding an expense in seconds, splitting it any way you like (equal, percentage or exact amounts, always down to the last paisa), settling up a group in the fewest possible payments, and tracking spending against budgets. The mobile app is written in Flutter and its source code is public on GitHub.
