A new app has been developed lately - the MoneyMind.MoneyMind in BlackBerry App World
It's a simple and useful expense tracker that allows to log all our expenses by dividing them into categories and display the reports.
It's also possible to export the data to a CSV file that can be opened in Microsoft Excel or OpenOffice Calc. Thanks to that user is able to analyze and check for what he is spending all his money. ;-)
MoneyMind is cheap - only $0.99 - but worth of downloading!
