The firm estimates Sora's iOS app has pulled in a total of 164,000 installs during its first two days, September 30th and October 1st. The day-one figure puts Sora's debut ahead of the performance of other major AI app launches, including Anthropic's Claude and Microsoft's Copilot, and puts it on par with xAI's Grok launch. Meanwhile, OpenAI's ChatGPT and Google's Gemini iOS apps had a somewhat stronger launch, with each reaching at least 80,000 downloads on day one.
