A mobile banking app is a software application that allows users to manage their bank accounts directly from their smartphones or tablets. With this app, customers can check their account balances, transfer money, pay bills, and view transaction history without needing to visit a physical bank branch. These apps are typically provided by financial institutions like banks and credit unions, ensuring secure access to personal financial information. Many mobile banking apps also offer features such as mobile check deposits and budgeting tools, making it easier for users to handle their finances on the go.
