Unfortunately I haven't found any decent applications for iPhone as far as money is concerned. So much so, I'm thinking about the kind of data and functionality I should put into an application myself.

For now, sadly, I keep all of my data and information within various spreadsheets and note things down in my diary until I can update on my personal computer later. However then again, I can't see myself using an application on my Mac to handle it. There's just much more power in a spreadsheet there.
