The ChangEd app is designed to help people pay off student loans using their spare change. The spare change is collected by rounding up purchases. Users link their bank accounts to the app and every time a transaction is recorded the app rounds it up to the nearest dollar; even dollar transactions are rounded up an extra buck. When a user hits $100 in spare change roundups the ChangEd app sends a payment to their student loan servicer.
The ChangEd app features a dashboard that lets users know how much they're saving, both in interest costs and with regard to how many years they're cutting off the life of their loan. The ChangEd app is currently only available for iOS but an Android version is in the works.
