Cash App is a peer-to-peer money transfer platform that works on Android and iOS. You can use this service to pay your share of utilities, manage your bills, and send money. A Cash app account can also be used to receive a Visa Cash App Debit Card once it has been verified and registered. The app allows users to make purchases as well as use their Cash App account funds at any shop. As an alternative, you can invest in stocks without any additional fees.
