Both Cash App and Venmo make it easy to pay your friends as long as you’re connected through the app or have certain items of the required information, such as an email address or phone number. However, Venmo focuses on networking with friends and family members and functions similarly to a social media network, emojis and all. Cash App can be used to pay and receive money from anyone if you have their email address, phone number, or $Cashtag. This might make it a preferred way to send money to people you don’t know.
