An app would be brilliant, provided it actually worked. Given the way ticketing and the shirts have been going, I wouldn't be confident!
But if done right, it could be great. Have ticket sales on there, club shop etc. Once the loyalty scheme is up and running the app could keep track of that. They could even have a section for the kids on there, maybe a County quiz with Vernon and a virtual sticker book. The idea has loads of potential.
Need to get the ticketing and club shop sorted first though, no point having an app if the main two features have issues.
