TikTok has returned to the app stores of both Apple and Android in the United States after being removed due to a divest-or-ban law enacted by former President Joe Biden, which raised national security concerns about its parent company, ByteDance. The app was inaccessible since late January, despite its service remaining operational. A Supreme Court ruling on January 17 upheld the ban, leading to TikTok's reinstatement by Apple and Android shortly thereafter. During TikTok's removal, there was a surge in secondhand sales of used iPhones pre-installed with the app, and competitors like Meta-owned Instagram announced new applications to rival TikTok. Users also explored alternative platforms like Clapper and RedNote during TikTok's absence.
