I've had this software for a few years, but I've used it daily for about the last four months.

I can't speak highly enough about how well this software does what it's designed to do. There were a few kinks for me learning how to handle my weekly pays, but the tech support was fast and got me going again quickly.

Basically, this software replicates the 'Envelope System' your grandmother (and at least one Syndicated Radio Personality) recommends, but instead of using cash envelopes, you use virtual software 'envelopes'. You can set up where to allocate your money for each paycheck ahead of time. If your pay varies, you must allocate every dollar before it will populate you envelopes - just as you would for an all-cash system. A 'catch-all' envelope called 'Available' is where any money you don't want to allocate (yet) will go.

You can customize your envelopes with logos and colors, and movement of money between envelopes is quite simple. Envelopes have histories so you can double-check whether you paid bills from your envelopes yet.

Once the iPhone version comes out, it will sync with the Mac version and it'll be just like having your envelopes with you - you'll be able to document purchases from your envelopes on-the-fly. Currently, I save my receipts and document them at the end of every day.
