Yesterday saw the full non-beta release of Lemon, a robust receipt tracking service that not only allows you to forward all your receipt emails into their service with a custom email address but also supplies you with an app to enable you to snap pics of paper receipts. The interface is clean in both the site and the app - getting started is easy. I will admit that, so far, I don't really see the service combing the emails I send it for monetary values and creating an easy to reference table of expenses (which is what I expected it to do). That being said, it does serve as a nice repository of money spent and an excellent way to not lose track of your expenses - assuming you file them away immediately into the system. Looking forward to seeing what this grows into.
