Real AI agent use cases, with sources and setup prompts
Short answer: There are two routes. The easy one is a personal agent with built-in phone tools: Grok Bot's iOS and Android apps can now read and send messages, check and add calendar events, set reminders, look up contacts and control Apple Home from a chat. The hands-on route lets a coding agent drive the screen: Phone Harness and iphone-use let Claude Code or Codex read the screen, tap, swipe and type on an iPhone (through iPhone Mirroring on a Mac or USB/Wi-Fi) or on Android over ADB, iCTRL does it on XCUITest, Hermes has a phone-harness plugin, and Phonebox gives agents their own cloud Android phone. Builders below used these to plan a day on the commute, add appointments by voice and order a Waymo through the real app. Keep payments, banking and messages to new contacts behind your approval.

With Claude's help he got Hytale to launch on a Galaxy S23 by using the game's ARM-based Mac build.
Some bugs only show up on a real phone even when tests pass, so a developer built duet: an AI agent tests a feature on a real Android phone and in browsers at the same time while you watch.

A demo shows Claude Code using a real iPhone: it reads the mirrored screen on a Mac with OCR and taps around like a person. It also works on Android over adb, with nothing to install on the phone.
iphone-use lets Claude Code, Codex or any MCP client read an iPhone screen as text, then tap, type and swipe in any app, including Health, banking and chat apps. It runs over USB or Wi-Fi on iOS 15+ and is self-hosted.
Phone Harness lets coding agents read a real phone screen, tap, swipe, type and check the result. iPhones are driven through iPhone Mirroring on a Mac, Android phones through ADB over USB or Wi-Fi.
Hermes Agent's plugin catalog has a one-install phone-harness plugin. The agent sees the phone screen, taps, swipes and types, so it can work with apps that have no API or plugin of their own.
Enable USB or Wi-Fi debugging on an old Android phone, connect it, and ask Hermes agent or Claude Code to test and debug your mobile app.
The Open Minis team open-sourced iCTRL, the iPhone automation tool they built to test their app. It runs on XCUITest but is designed for AI agents, so Codex, Claude Code, Hermes and OpenClaw can tap, type and read the screen.
Phonebox lets AI agents control cloud Android devices with no emulator or ADB: open apps, tap, type, swipe and scroll, install APKs and automate mobile apps through MCP. It works with Claude Code and Codex.
