You set up a category for something you would like to control your spending on. I like to use coffee as an example. Say you want to spend $40 a week on fancy coffee shop coffee. You create a category for coffee and set it up for $40 dollars a week. Every week your coffee account gets $40 dollars added to it. You record the coffee you buy through out the week. Now you always know how much you have left to spend on coffee, and how much you have already spent.
For a more fun game like experience use trickle mode. Instead of the $40 for coffee going in on the first day of each week, it trickles into the account a little at a time. The game is to keep the Spendable amount above zero at all times. If you can do that you will have mastered your own spending destiny!
