As a hobby project, I'm working on a tool to help improve spending habits. I'm not crazy enough to imagine I'd ever reach feature parity with mint, but I personally know plenty of folks who use the well known personal finance tools yet seem to make a lot of careless purchases they later regret. And while mint is fine for what it does, I don't think it really points you in the direction of disciplined, thoughtful spending. If you want to stick to a budget but you find it hard, I think there's an opportunity for a more focused tool.

More than simply building a savings account, the other side of the coin is making your spending more meaningful by reducing impulsive buying. Saving a few bucks here and there with coupons or promotional discount is way too easy to spoil with just one thoughtless purchase.
