With the Shell Service App, you can easily pay for fuel at Shell stations in Denmark. In addition, you can pay for car wash at more than 100 Shell stations.
The add payment card section is written in Danish so I had to guess what it was asking. After my banking app quickly agreed to the addition of the Dansk Shell group the shell app had frozen and just kept returning me to the add payment card section, starting again. This happened twice so I gave up.
Useless
Doesn’t display petrol stations or car wash locations (unless you have to sign up, which I refuse to add my card details just to view locations, which was also written in danish rather than English)
