Most banks integrate Wero into their online banking app, but some (e.g. mine) use the dedicated app for Wero (It's just called wero on google play and iOS). You still sign up with your bank account though.
The critical feature that Wero needs is adding money to your account balance via SEPA instant or credit card. That way users without participating bank accounts can join.
