１８祭 Goods App is an Android application developed by Sony Music Solutions Inc. This app is designed for the fans of the Japanese band Kanjani Eight who attend their concerts. With this app, users can create a list of the goods they want to purchase at the venue in advance. Then, they can simply present the QR code at the register to place their orders.

The app is easy to use and provides a convenient way for fans to order their favorite goods without having to wait in long lines. However, it is important to note that the app only allows users to create a list of the goods they want to purchase and does not guarantee the availability of the items.
