Earmark Envelopes - Budget Tracking, Saving, Money

All of my spending money lives in one checking account, and I need a way to track how much money remains in each of the categories that I spend from often. Many of my purchases are done online, so I needed a digital way to track some envelopes.

Step 1: Click the "+" button to create a new envelope with the amount of money you've currently budgeted (e.g: Gas, $175).

Step 2: You've finished pumping gas; the pump reads "$37.21". Launch the app, type "37.21" in the Amount field, and click "-" to subtract.

Step 3: You now know that you have "$137.79" left in your Gas budget.
