What tool do you use for simple money management?

Wondering what tool(s) you guys/gals use for simple money management. I've tried Mint in the past, but I don't need a budgeting tool, per say, and it's bells and whistles were more than I needed.

I seem to simply want something where I can manage my inflows and outflows and figure out what I have left at the end of each month.

Any simple tools out there for this that maybe I have not come across?

What do you use?
