The main use case of a banking app is checking how much money you have. That's why the first screen of the app shows your accounts. By clicking on the account you'll see the transactions. The navigation bar on the bottom of the screens gives you quick access to the four main sections of this app.
What's special for this banking app is that at any moment you have the option to get in contact with your personal account manager shown on top. So if there's a problem and you need help or you need information about a specific financial product you'll get help instantly.
