KMyMoney

KMyMoney is a lightweight, open-source desktop finance manager that tracks checking accounts, credit cards, loans, and investment portfolios in one place. It's part of the KDE software suite and works on Linux, Windows, and macOS, storing all your data locally in an encrypted file. The interface is simpler than GnuCash but still gives you comprehensive tools for budgeting, forecasting, and reporting.

It's ideal for open-source enthusiasts and people who want a desktop app without the complexity of full accounting software. KMyMoney strikes a middle ground between the simplicity of mobile banking apps and the power of desktop accounting packages. If you prefer keeping your financial data on your own computer rather than in the cloud, and you're comfortable with open-source software, KMyMoney provides a solid, free alternative to Mint's tracking capabilities.
