Remodex Is the Best Codex Remote Client for iOS (Until OpenAI Releases an Official Codex Mobile App) - MacStories
18 hours ago - For now, though, Remodex is the only app I’ve found that lets me do all this with a lovely Liquid Glass design that fully embraces iOS 26 and does not resemble a command-line utility. Before writing this post, I took the opportunity to chat with Di Pietro about Remodex. “I used the Codex App Server to build the app”, Di Pietro confirmed, adding that “what I love about OpenAI is that they provide tools like this, which we can use to build our own open-source projects”. Indeed, OpenAI’s embrace of the open-source community and third-party integrations built on top of Codex is, at the moment, a major differentiator from Anthropic, whose Claude Code is notoriously closed off.

Codex in the iOS app?
They released the iOS version roughly the same time they released Codex itself, within a week at the latest. I know Sama had tweeted about it too. Edit: mb this could’ve been more helpful. Like others said, it doesn’t show up until you use it in the web version first. More on reddit.com

r/OpenAI on Reddit: Codex in the iOS app?
July 5, 2025 -

Hey yall, just noticed something odd, and maybe it’s some a/b testing shit? Up until now my understanding was the codex is only on the browser version of ChatGPT (I’m a plus user if that matters) not even Mac app or anything.

However today I was making some adjustments to control center on my iPhone and noticed there’s an ‘open codex’ button under ChatGPT features, and goes right to a seemingly hidden codex window within the app. Can’t for the life of me figure out how to initiate it from the app directly, but thought this was an interesting find!
