# App Badging API

## Overview

App Badging API allows installed web apps to set an application-wide badge on the app icon, shown in an operating-system-specific place such as homescreen, taskbar, or dock.

Badging makes it easy to notify the user without any interruption, when there is a new activity that might require their attention, or to show the number of unread notifications.
