Twitter's subscription-based service "Twitter Blue" listed on App store

Twitter's new subscription-based service "Twitter Blue" has been listed on App Store. Though Twitter has provided no more information on the service, information circulating online claim that the service could enable undoing tweets. The in-app purchase is priced at 2.49 pound in the UK and 2.99 dollars in the US.

Though listed on App Store, it is not fully enabled for users yet. Twitter had previously said that it is working on special features for paid subscribers. It is also attempting to generate revenue by means beyond advertising, including subscription services and other ways to offer individuals and businesses access to special features on the site.

Technology blogger Jane Manchun Wong, who claims to be the first paying user of the service, said it includes an "undo tweet" feature and a "reader mode" to make reading long threads easier.
