Twitter has finally come to the aid of celebrities and digital influencers (we still don't know what digital influencer means) by launching an app that helps them grow their own personal brand. It's called Engage, and it's not for unwashed digital peasants like us.
Engage is essentially an analytics app that helps the big names of the Twittersphere (not us) build their following and interact with their most important and loyal fans.
It filters mentions and replies, thus eradicating all the vitriol and weird sexual advances that celebrities (probably) receive, showing only mentions by verified users or users who tweet at that celebrity a lot.
There is also an advanced analytics tab that shows exactly how many impressions your tweets are getting over time and a tab that allows you to see the performance of individual posts.
Probably the best aspect, for big names, is that the app gets rid of that pesky timeline, so celebrities can tweet in peace without being bombarded with the goings on of the plebs that they keep forgetting to unfollow.
To be clear, you and I can download Engage, but unless you want advanced analytics on why you're hilarious Roy Hodgson tweet only got two likes, then it's probably not worth the bother.
