My wife and I have used Microsoft Money for a few years to balance our "checkbook" (I use quotes because we rarely write checks but mostly use debit cards). It would be nice if there was an app where we could put in purchases and have it keep track and break things down like Money does. But it would need to sync with a server or something because we both have iPhones and would both be entering items using the phones. A web interface would be nice too. Does such a beast exist? I'm not even sure how to search for one because I don't know if I have the terminology right.
