An accounting program has been for sale for many years on the Palm OS.  It needs to be ported to the iPhone/iTouch.
This program has the ability to have multiple checking accounts, loans, reoccuring transactions and export/import from a computer
.
I have the user manual (with screen shots) for the current Palm Product and all the Palm code that can be used as a reference.

If you have a palm, you can download the program and view how it works.

The new iPhone app will have some color added but no other features will be added.  Obviously the iPhone version will use iPhone technology.
