Twitter has restarted a service dubbed Twitter Blue, where users can pay a monthly fee for a blue checkmark, along with the ability to edit tweets and upload high quality video.
Apple users, however, will be charged more.
The company says the revamped service will cost $8 a month on the web, or $11 a month if purchased through an app on iPhones and iPads, where in-app transactions are processed through the company's App Store, which generally levies a 30% commission.
