GnuCash version 2.6, released earlier this month, fixes many of the nagging problems in earlier versions and is more convenient to use. It tracks bank accounts, investments, income and expenses. You can use GnuCash just to handle your checking and savings accounts -- but it is capable of doing much more. GnuCash is based on professional accounting principles to ensure balanced books and accurate reports. However, if you venture beyond basic banking registers, you might find its double entry bookkeeping procedures a bit intimidating.
