sim-use is a cross-platform Swift CLI that gives AI agents the ability to observe and act on iOS Simulator and Android emulator/device screens. It converts the accessibility tree into a token-efficient text outline and lets agents tap elements by alias, ID, or label without coordinates.

Use cases

  • let an AI agent verify UI changes it made in an iOS simulator
  • automate tapping through Android emulator screens with an LLM loop
  • dump a compact accessibility outline of a mobile app screen for an LLM
  • script mobile UI flows using element labels instead of coordinates
  • close the observe-act-verify loop in agentic mobile development
  • drive iOS Simulator and Android devices from a single CLI

When to choose

  • you want AI agents to interact with and verify mobile app UIs on iOS Simulator or Android emulators
  • you need a token-efficient screen representation for LLM reasoning instead of screenshots
  • you want coordinate-free UI automation driven by accessibility data

When to avoid

  • you need to automate desktop or web browsers rather than mobile simulators and devices
  • you require pixel-level visual testing or screenshot-based verification
  • you need a GUI-based record-and-playback mobile testing tool
