EuroBudget is a checkbook management software written in pure Java 2. It allows you to do your own accounting for free. Of course it has a limited set of features but it is enough for my own purpose. With it you should be able to do your accounting anywhere and on all computer, nevertheless their operating system. You will import qif file from your bank internet site to enter quickly most of your entries. You will create some graphical reports that will help you to understand how you spend your money and where you could reduce expenses.
In spite of the Engrish description and the Java, it works pretty decently, but it loads slow as shit. If your OS hasn't got a decent checkbook managing app, this is one to consider.
