Mvelopes simplifies the way you budget by helping you track your spending in different categories you create, which could include groceries, entertainment, and dining out. Once you hit the limit you’ve set for yourself in a specific category, you stop spending in that category, if possible. This is a different approach from some other budgeting apps, including Simplifi and Rocket Money. These types of apps can also help you track your spending, but they don’t necessarily use the envelope strategy.
