What's A Few Bucks Between Friends?
Money is often a source of friction between spouses and friends. Clevlab has a friendly little app to avoid those small misunderstandings from turning into bigger ones. Friendly Budget allows you to track who paid what to whom, and what the share of the expense you and your friends and family have incurred - perfect for holidays when travelling with friends and family. There's a version for both Windows Phone 7 and Windows Mobile 6.5, though unfortunately I can't check either out due to geographic restrictions. It's a neat idea and certainly worth a quick look.
