Elon Musk is taking Apple to task over its lack of promotion of not only X but the Grok app, as well. Musk wondered aloud on social media why the App Store does not have X or the Grok app, which is an artificial intelligence chatbot created by xAI,

At the time of writing, ChatGPT is listed as Apple’s top free iPhone app in the US, with Grok ranked as the sixth. China’s DeepSeek AI briefly managed to take the top App Store position from ChatGPT in January, however, disproving Musk’s claim that it would be impossible for other AI apps to do so.

The billionaire said in posts on X that the consumer tech giant was violating antitrust laws by giving preferential treatment to OpenAI on the App Store.
