I recently released an app on the marketplace and would like some user input. The app is a checkbook register that allows the user to enter transactions and organize them by type (such as gas, groceries, etc). What I need is some common things that people spend their money on to add to that list of categories. Also, if you could provide ways in which you commonly receive money (such as paychecks, etc) that'd be helpful as well. If you're curious about the app, its called "Checkbook". There are two versions, the basic (free) one and the one I am requesting help with, which is $0.99. Thanks in advance for the help.
