OpenCyclone launches as an open-source AI phone app for stock Android

OpenCyclone is a free, open-source app that turns an existing Android phone into an AI phone, reading app screens on a hidden display and asking for approval before any irreversible action. It requires Android 12 or later, a one-time setup script on a computer, and a model provider account, with support for ChatGPT sign-in, OpenRouter, a pasted key, or a local model plus tools via the Model Context Protocol. The author says it was built by one person with AI coding agents on top of an existing open-source project, is early software that handles short single-app tasks better than long cross-app ones, and has not yet published AndroidWorld, MobileWorld, or its own safety benchmark results.
