This is by far the best budget app I've found so far. It just works beautifully without being too complex, but is robust enough to handle all of my expenses. In comparison, I had to leave recurring expenses out of my last app because they just complicated things so I was only using it to track my variable budget.
I LOVE how it handles fixed expenses and reminders - This app serves double duty as my main method of bill payment reminders as well (previously done with a convoluted system using Things and iCal, which works fine but why bother?).
