All of that can be handed via your bank's website, ATMs, a credit card, or even (god forbid) writing a cheque.
A lot of banks in the UK have mobile-app-exclusive features / services. I imagine this is because of security, but it also makes little sense. If you don't have a smartphone it is about 5x harder to do anything online-banking related here. I remember when I went camping a bit ago my phone died and I was unable to unfreeze my card.
Also, cool username =)
All of which (except the cheque, which we can ignore - nobody in the UK has a chequebook any more) depend on the same communication infrastructure that the app does.
