Codex Mobile: Branch Selection, Worktree Creation & Goal Mode on iOS
CodexChatGPT for iOS version 1.2026.153 substantially expands the Codex mobile experience with three developer-facing upgrades. Users can now select a Git branch, create a worktree, and run environment setup scripts when starting a new thread from mobile, achieving parity with the desktop new-thread workflow. The update also introduces /goal support on mobile, allowing developers to define multi-day objectives and track progress directly from their phone. A new Codex profile screen surfaces usage statistics and token activity charts, and inline review comments are now available when examining changed files on mobile.

Full Git Workflow Control, Now on Mobile
When Codex mobile launched in May 2026, developers could start and steer tasks on a connected Mac but lacked the ability to control which branch or worktree a new thread targeted. That gap is closed in ChatGPT for iOS 1.2026.153, released June 9, 2026. The update adds branch selection, worktree creation, and environment setup script execution directly to the new-thread flow on mobile.
Previously, starting a task from a phone could accidentally kick off work against the primary checkout, for example main, rather than an isolated feature branch or worktree. Now, when creating a new thread, mobile users see the same Git target controls as desktop users: they can choose an existing branch, create a new worktree, and optionally run setup scripts to prepare the environment. This makes it safe to assign new tasks remotely without risking unintended changes to the primary checkout.
Goal Mode Comes to Mobile
The June 9 update brings /goal to Codex Mobile, allowing developers to create and manage long-horizon goals from their phone. With goal mode, a developer can define an objective and success criteria, then let Codex work toward it across multiple sessions, even overnight. Goal state persists across turns and session breaks, with progress tracked and surfaced in the thread.
Goal mode was graduated to general availability across the desktop app, IDE extension, and CLI in late May 2026. Its arrival on mobile closes the final surface gap, making it consistent to define, monitor, and update goals regardless of which device a developer is using.
Codex Profile Screen and Usage Insights
A dedicated Codex profile screen now appears in the mobile app, presenting usage statistics and token activity charts for the current account. Developers can see how much compute their threads have consumed over time, which mirrors the activity insights feature that arrived in the desktop app's profile section in the June 4 App 26.602 update.
Inline Review Comments and Side Chat
Two more workflow improvements ship in 1.2026.153. Inline review comments are now available when examining changed files on mobile, bringing the code review experience closer to what developers expect from desktop tools. Separately, a side chat can be opened from any selected section of transcript text, making it easy to ask a follow-up question about a specific part of Codex's output without interrupting the main thread.
Additional polish includes refined attachment handling on Windows hosts, skills and plugins moved to the inline composer display for faster access, and improvements to queued prompts, navigation, tool activity indicators, and archived thread browsing.
