"This is a great app for people who are ready to start creating a budget based on their cash flow. The envelopes system is similar to putting allocated amounts of cash into actual envelopes per month, which is charmingly old school. Use the Envelopes section to divvy up your monthly budget and understand spending habits in each area of your life. For items that land in your recurring budget, select the time frame as monthly, weekly, semi-monthly, or every two weeks, and then pick a start date." -Daily Worth
