agent-device vs Observer
agent-device: agent-device gives coding agents a live app feedback loop through a CLI, a built-in MCP server or a typed Node.js API. Agents can inspect, control, debug and verify apps on iOS, Android, HarmonyOS and other platforms.; Observer: Observer lets you build micro-agents that watch your screen, camera, microphone or clipboard and run a small local model on a loop. When the model spots a condition, JavaScript tool code sends a notification (email, Discord, Telegram, SMS, WhatsApp), records a clip or writes to memory.
