Our Mission

We believe financial tools should be accessible, private, and simple. Too many apps lock your data behind accounts, mine your information, or charge exorbitant fees for basic features. Expense Tracker was built to be different: a tool that respects your privacy, works offline, and puts you in full control of your financial data.
