Put simply, KMyMoney is a personal finance manager by KDE. It enables users of open source operating systems and applications to keep careful track of their personal finances by providing a broad array of financial features and tools.
The principal goals of the project are:
Feature Parity. KMyMoney intends to provide all important features found in the commercially available personal finance managers. Although every release of KMyMoney gets closer and closer to that goal, there is still work to be done.
Ease of Use. KMyMoney strives to be the easiest open source personal finance manager to use, especially for the non-technical user.
Correctness. Based on tried and tested double entry accounting principles KMyMoney ensures that your finances are kept in correct order.
