The cost of Twitter Blue for iPhone users will increase, according to a study

According to The Information, Twitter (TWTR) will increase the cost of its Twitter Blue subscription service for those who join up using Apple's (NASDAQ:AAPL) iPhone.

According to the news source, who obtained the information from a source briefed on the plans, Twitter (TWTR) would charge $7 per month for web-based registrations but $11 per month for App Store registrations. Previously, the service from Twitter (TWTR) cost $8 a month, and it was exclusively accessible through the App Store.

The Information claimed that Twitter (TWTR) informed its staff that Twitter Blue, which allows users to buy a blue checkmark used for verification purposes, would relaunch on Friday. When it first debuted earlier this year, it was riddled with issues.

Seeking Alpha contacted Twitter (TWTR) and Apple (AAPL), but neither company responded right away.

The 30% fee that Apple (AAPL) charges for services purchased through the company's iOS apps is probably to blame for the price increase for iPhones. The internet giant, however, has not had a problem with businesses changing their price points to get customers to subscribe to services other than its apps.

Apple (AAPL) has also negotiated cheaper commissions with businesses, most notably Amazon (AMZN), to allow for the upload of software to the App Store.

The news comes days after Elon Musk, the CEO of Twitter (TWTR), and Cook, the CEO of Apple (AAPL), met at the headquarters of the tech giant in Cupertino, California.

A few days after Musk openly questioned why Apple (AAPL) had halted its Twitter advertising budget, Cook praised Musk for giving him a tour of the Apple headquarters. The 51-year-old Musk also asserted that Apple (AAPL) threatened to remove Twitter from the App Store but did not provide an explanation.

Since then, Musk has confirmed that Twitter's (TWTR) largest advertiser, Apple (AAPL), has "completely" resumed advertising on the social network.

According to a source on Wednesday, Musk's bankers were considering replacing some of the high-interest debt he took on in the $44 billion purchase of Twitter with new margin loans secured by Tesla (TSLA) stock.
