Twitter did not explain why Apple users will pay more, but in the media there are reports that the company is looking for ways to offset the fees charged by the App Store.
Twitter Blue was launched at the beginning of November, but later its work was suspended due to the increase in the number of fake accounts. It was then scheduled to launch again on November 29, but the decision was again postponed.
Elon Musk, who in November made Twitter a private company for $44 billion, in a series of tweets listed various claims against Apple, including the 30% commission the iPhone maker charges software developers for in-app purchases.
He accused Apple of threatening to block Twitter from its app store and said the iPhone maker had stopped running ads on the social networking platform.
However, after a meeting with Apple CEO Tim Cook, he revealed that the misunderstanding about removing Twitter from Apple's app store was solved.
