Cash app is an app that is used to transfer money from one person to the other or best put from one account to the other. Initially, it was hard for me to go to the bank in trying to transfer money form my account to somebody’s or from my account to another account. But with cash app, you can just stay at home make an instance transfer from one account to the other. Only problem about the app is, there is a fee that you have to pay before you make the transfer whiles I could have done it from bank account to bank account without paying anything but it will take a long time to reflect in the receiving account. Cash app has about 24 million users right now which means a lot of people are using it and it is because of how effective it is.
