With the Rize app, you can either earn interest on cash savings within the app, or earn more interest by allowing the app to invest your money in exchange-traded funds. Simply set a goal amount, notifying Rize how often it may pull money from your bank account, and how much. Then choose to have it earn interest within the app, or through investment, and Rize will take it from there. It also offers a few features to help you save faster. For example, you can use the “Power Up” feature to automatically increase your contribution each month by a set percent.
