The World's Online Festival (WOLF) (formerly Palringo) is a British messaging and gaming platform with apps for iOS and Android. Users can create groups where they can send text, image, and short audio messages. Groups feature a Stage which provides five live microphone slots for users to chat. The app features a store where users can purchase in-app credits that can be used to buy additional features, utility chatbots and games, and to send in-app gifts to other users. Users have a reputation level that increases from actions such as playing chat games or purchasing credits.
