That's nice (when it's free), but banking apps are clunky, unfriendly, heavy and slow. Unicredit and Intesa, two main Italian banks, both have apps that are atrocious to use and riddled with annoyances.
People want an easy and quick way to send/receive money (Satispay does that almost well).
And for some banks Wero seems like it's going to be available through your existing bank app. Which is a no-go for me.
