Badge APIs
Badging is a concept used in both iOS and Android platforms to indicate to user, information about an app or an app menu. Badging works as a notification to the users. Based on the information provided, user’s can take some action. However, badging does not explicitly ask the users to take any action.
The number of unread messages on your mobile device that is indicated is an example of the badge API.
