What is App?

In short

An app is the phone software a customer uses to manage a service, and every brand in this group offers one.

An app is software that runs on a phone, so a customer can manage a service, check usage or pay without opening a website. It is the everyday control point for a broadband line, a wallbox or a smart meter. Every brand in this group states it offers one, including CHECK24 Partnerprogramm and Cord EV, and also Alperia, Autel Energy and British Gas - Hive - Smart Home & Heating.
