In its debut week, OpenAI's Sora app achieved 627,000 downloads on iOS, surpassing ChatGPT's 606,000 downloads during its initial week. This comparison is somewhat skewed, as ChatGPT was only available in the U.S. at launch, while Sora was accessible in both the U.S. and Canada, contributing approximately 45,000 installs from Canada. Despite being an invite-only app, Sora's performance is impressive, especially considering it reached No. 1 on the U.S. App Store shortly after launch. The app's ability to generate realistic deepfakes has garnered significant attention, with users creating content featuring deceased individuals, prompting discussions about ethical implications. Daily downloads peaked at 107,800 on October 1, 2025, showcasing sustained interest in the app.
