While TikTok operates in the United States under new ownership, Apple has deployed technical restrictions to block iOS users in the United States from downloading other apps made by the video platform’s Chinese parent organization ByteDance. ByteDance owns a vast array of different apps spanning social media, entertainment, artificial intelligence, and other sectors. The leading one is Douyin, the Chinese version of TikTok, which has over 1 billion monthly active users. While most of those users reside in China, iPhone owners around the world have traditionally been able to download these apps from anywhere without using a VPN, as long as they have a valid App Store account registered in China. That’s not true anymore. Starting in late January, iPhone users in the US with Chinese App Store accounts began reporting that they were encountering new obstacles when they tried to download apps developed by ByteDance. WIRED has confirmed that even with a valid Chinese App Store account, downloading or updating a ByteDance-owned Chinese app is blocked on Apple devices located in the United States. Instead, a pop-up window appears that says, “This app is unavailable in the country or region you’re in.” The restriction appears to apply only to ByteDance-owned apps and not those developed by other Chinese companies. Apple and ByteDance declined to comment. TikTok USDS Joint Venture (the new entity controlling TikTok’s US operations) didn’t respond to WIRED’s request for comment. The timing and technical specifics suggest the restriction is related to the deal TikTok agreed to in January to divest Chinese ownership of its US operations. The agreement was the result of the so-called TikTok ban law passed by Congress in 2024, which also barred companies like Apple and Google from distributing other apps majority-owned by ByteDance. The Protecting Americans from Foreign Adversary Controlled Applications Act states that no company can “distribute, maintain, or update” any app majority-controlled by ByteDance “within the land or maritime borders of the United States.”
