Housekeeping Book allows you to store and display your regular monthly (or weekly) spending and income, to let you see at a glance how much is left over for other things. You can add an arbitrary number of items, assign a description, a value and the category (earnings/spending). The list is written to database and displayed in numerical order - income first, spending second.
You can edit an entry by tapping on it. When more items are entered than the list can hold, you can scroll the list with the appearing arrow buttons or the keys on your device. To keep your list private, you can set a password.
