Newbie here, so be gentle!

Finally replacing our old Fabia with a new Scala, due March.

I have the MySkoda app loaded in anticipation, but do I need any other of the Skoda apps?

A snurfle round the Skoda website does not help.

I don't think so. It seems most older apps are being replaced by the "My Skoda" app. 

 

Just after you get the car you will probably get a "free trial" of an app called Traffication. It is harmless but inconsistent.
