Cash Trails is a great app for figuring out where all those dribs and drabs of dollars are going. I use it to track my personal expenses, and a number of household categories. Its easy to switch expenses around from account to account and tag with different categories for analysis later.
I do wish there were an iPad-sized version. It doesnt even need a different interface, but a non-jagged graphics version would be great to use. Despite that, its still a 5-star app.
