I'm looking for an app for IPhone that will help me budget ahead of time for a trip. Ideally, I would like to budget two separate trips at once so I can see which destination is most suitable for my funds available. The app store shows lots of apps for expenses during a trip, but not really budgeting. I suppose I could use something online as well. Any ideas?
Google Docs (don't think the Safari support is that great, but I believe there are some 3rd party apps that sync with it) or some other spreadsheet?
