Ive tried four (yes, four) - JetSet is best!
I think JetSet is the best business expense app available. I emphasize business, because it is clearly designed for business travelers, which I appreciate. I have purchased and used four of the other expense apps on iTunes. JetSet has a better design and better functionality than any Ive used. The flip-screen design is smooth and makes entering expenses quick and painless. The databases and connectivity to the address book really helps reduce the amount of typing required. The built in calculator is also a great feature. Having the ability to e-mail reports to and import the data to Excel (without drama) sends it over the top for me. The only things that could make the app better are foreign currency support (according to the web site this is coming in the next update) and ability to track payment methods (which I am now tracking in notes). Despite the room for improvement, I think this is the best app for the money.
