I'd like a home finance/budget application that is made for couples. In other words, my wife and I each with our iPhones could independently enter our spending and it would update both phones so we'd each have access to the total budget & balances. Real-time update would be cool but on-network update once we get home would be fine. Does this exist? Another approach would be an iPhone app that syncs with your desktop Intuit Quicken or MS Money (yeah right). Thoughts?
