Periscope is a live video streaming app for iOS and Android that allows users to tweet out a link to their Live Stream. The users can also choose whether or not to make their video public or viewable to only certain users and through the Limited by Broadcaster option, they can also disallow comments.
The App allows viewers to send "hearts" to the broadcaster by tapping on the mobile screen as a form of appreciation. The maximum number of users that can be followed is 8,000.
Both the scoper and viewers of the scope are able to block viewers and if enough scopers block a user, they are blocked from the scope. A user who receives more than 4 blocks from 4 different scopes gets shadowbanned temporarily. A new feature to broadcast live in landscape view was later added to the App.
