Twitter has listed a 'Twitter Blue' subscription service on app stores.

The social media platform looks to be getting ready to test the new service - which is listed at £2.49 in the UK and $2.99 in the US - which is said to include special features for users.

According to reports, those who sign-up could get a reader mode to help with longer threads, and even an "undo tweets" tool.

Tech blogger Jane Manchun Wong says as well as the undo tweet option, the service also includes customisable colour schemes for the app and Twitter app icon itself.

Although Twitter hasn't commented on Twitter Blue or the blogger's claims, they told the BBC that they were focused on increasing "revenue durability".
