Develop a Mac Application--2

I would like to develop an application for iPhone named: “Personal accounting butler” to help people managing their finance easily and conveniently. With this app, users can record any cash they have paid during any period they have set up before. For example, users can record each and total cash outflows during one month. In addition, users can classify payments by themselves. For example, they can classify payments in three ways: Entertainment, Life and Food. In terms of each classification, it should have a remark to make it more specific. For instance, 5 pounds paid in “Toothbrush”（Remark）in “Life”（Classification）. Furthermore, the style of the data recorded in app can be shown like income statement，Classification on the top, Remark on the left side and Payment on the right side.
