BDUI Go opens mobile apps that are described in JSON: their screens, navigation and API requests. Authors create these apps in the BDUI web dashboard and share a link or a QR code. You open it in BDUI Go, and the screens render natively on your iPhone. Each app opens inside BDUI Go, so there is nothing extra to install. When the author publishes an update, you get the new version without reinstalling anything or waiting for an App Store update. A JSON description is data, not code: it lists which components to show and which requests to make.
