The Mint App and website at

It's a great tool for budgeting your personal finance. You can attach bank accounts, credit cards, etc to it (or not). By attaching accounts you get to see a full picture of how spend and save. You can create a budget with or without accounts attached.
I found a couple bugs and contacted INTUIT, but it's still worthwhile.
And it's free.
If you're a budgeter you may want to check it out.
I'm nuts about it and use it daily.
