Digit was designed to be as useful as possible while requiring almost zero attention. Once you download the app it starts working in the background, monitoring your spending habits while comparing them with financial information such as your monthly income and savings goals. It makes some calculations and then automatically places very small sums (between $2-$17) in your tiered savings accounts every few days.
By using Digit, you can save for vacations, pay off outstanding loans or debts, or save for the unexpected. It uses advanced calculations that know when it’s okay for you to save and when you need to keep the money in your primary bank account. You can use the service for free for 30 days, and then it’s only $2.99 for every following month.
