Is it safer to use an app or a browser for banking?

Irene wants to know why she should use a banking app instead of logging into her bank accounts with the Edge browser in Windows 10

Why should I use a banking app instead of logging into my bank accounts with the relevant passwords via Windows 10 and Edge? Which one would be more secure? Irene

Over the past five years or so, I feel the consensus has changed to using apps. However, it depends on the devices, banking software and browsers, what else is loaded on the device (either knowingly or not), and the communications network.
