ChatGPT Leads App Store Downloads as Grok Falls Out of Top 25
Sensor Tower data shows OpenAI's ChatGPT leading mobile downloads, with Gemini second and Claude third, while xAI's Grok has dropped out of the top 25.
OpenAI's ChatGPT holds the top spot for AI app downloads on the Apple App Store, according to Sensor Tower data reported by 24/7 Wall St.. Google's Gemini ranks second, followed by Anthropic's Claude in third place. xAI's Grok, meanwhile, has fallen out of the top 25 entirely on one chart and sits at 22nd on Apple's own ranking.
The download figures offer a snapshot of consumer adoption in an increasingly crowded AI assistant market. ChatGPT's continued lead suggests OpenAI retains strong brand recognition and user momentum despite aggressive competition from Google and Anthropic. Grok's steep decline is notable given xAI's high-profile launch and integration with the X platform — the numbers suggest that visibility on a social network hasn't translated into sustained standalone app demand. For enterprises evaluating which platforms their customers actually use, mobile download rankings remain one of the few public proxies for consumer-side traction in a market where usage data is otherwise tightly held.
