Users can also customize their Trends panel to display topics trending in a particular location or based on the content they already follow in the app.

The app update also modifies some aspects of user experience, including allowing users to invite social contacts to join Twitter from the mobile app and automatically notifying both the original poster and the re-tweeter when a user replies to a retweeted tweet.

Twitter also continues to invest in Vine, bundling improving playback into today’s update. Earlier this week, the video app began allowing users to shoot video from the front-facing camera on their mobile devices.
