Systems and techniques are described that enable users to interact and share content through a social network application and/or service with other users. In some examples, a social networking system determines that at least two applications are installed on a device and are both useable to share content between a first account and one or more contact accounts. The social networking system may detect an event that causes a change in a badge count, may determine which of the applications to use to display the change, and may output the badge count change to the determined application(s).
