Codex App August 18, 2026 Changelog

This update is all about making the app more reliable for managing coding tasks from your phone. It matters most to students or developers who use their iOS device to review code, talk to the AI, and keep track of remote projects without getting slowed down by glitches.

What's new

• Quick-launch for Codex Remote: You can now change your settings so the app opens straight into "Codex Remote" (a tool that lets you manage coding tasks on a different, more powerful computer) instead of the regular chat screen.
• Better tool forms: The app now supports standard "MCP forms" (on-screen forms used by outside software tools) and lets you approve or edit messages before the AI acts on them.
• Smoother file access: If you have linked folders, tapping them now opens them right up in your iPhone's Files app.

Improvements

• Smarter project picker: When you start a new chat, the project menu now accurately shows the correct projects for the specific computer you are connected to.
• Better voice features: You can now use voice commands directly from the screen where you build tasks. The connection is more reliable, and your tasks will keep running in the background even if you switch to another app.
• Faster code reviews: Reviewing "diffs" (the highlighted changes made to your code) is faster and less likely to crash, even when you are working in huge projects with lots of files.
• Easier retries: If a task message fails to load, you now get a simple "Retry" button to try again.
• More reliable connections: Pairing your phone with your computer is smoother, and the app will no longer freeze while checking if your devices are properly linked.
• Clearer AI updates: The app now shows better notes on what the AI is doing and keeps showing live progress right up until a task finishes.

Fixes

• Giant responses: Fixed an issue where really long task answers would fail to load.
• Disappearing tasks: Fixed a bug where your tasks would vanish or become unclickable if you left the app idle, lost your connection, or went back to your task list.
• Stopped bad messages: If you cancel or edit a "steering message" (a note you write to guide the AI's current task), the app now makes sure the old, canceled version doesn't accidentally get sent.
