Surround is a client to play Go online with other players on the website online-go.com (Online Go Server - OGS). OGS is a very popular Go Server with a friendly community, and this app aims to provide the best OGS experience on iPhones and iPads. Features: - Play Go with other Go players on OGS, either live games or turn-based (correspondence) games. - Observe other live games that are currently being played. - Chat with other players. - Get a glimpse of your correspondence games on your home screen with a widget. - Receive notifications when it is your turn in correspondence games. - Beautiful dark mode.
