- iPhone Use is described in the source as a tool that helps AI work tools such as Codex, WorkBuddy, and Doubao (豆包) Work open apps, read the screen, tap, scroll, and enter text on an iPhone connected by USB.
- It uses WebDriverAgent (WDA), managed by Appium, which is an automation execution service installed on the iPhone that receives external commands. Users must sign it with their own Apple developer team and install and run it on the iPhone. The source states that execution data and signed builds stay inside the Mac.
- The Codex plugin sends anonymous usage statistics by default. The source says they can be turned off by setting IPHONE_USE_ANALYTICS=0 or DO_NOT_TRACK=1 and then restarting the MCP service. The source states that the WorkBuddy and Doubao Work adapted versions have these statistics off by default.
- The source says connection reuse and batched actions reduce round trips with the AI model, but this is the development team's claim. The source adds that completion speed depends on app state, USB and WDA state, and model response.
O: This is a suggestion for a test where a product planner who has never had Codex or WorkBuddy operate an iPhone app asks an AI to type a long sentence into a notes app, and then checks the content directly before saving.
X: It requires a full Xcode installation, device trust, developer mode, and signing with the user's own Apple developer team. The speed improvement is the development team's claim, so actual completion time will vary depending on the app and the USB connection.
