PhoneCap, a tool that logs what Android apps send and receive

The full story
PhoneCap is a command-line tool built with Claude Code for seeing what a mobile app is actually contacting: image servers, ad and tracking endpoints, API hosts. It boots an Android emulator with a writable system image, installs mitmproxy's certificate system-wide so HTTPS traffic can be inspected, and logs every request to text and JSON files plus a self-contained HTML report. For apps that pin their certificates, a bundled Frida script switches pinning off.
It runs on Windows, macOS and Linux, with the platform-specific parts kept in one file, and a 'doctor' command checks the setup first. The maker built it to avoid hand-rolling the proxy, emulator and pinning bypass every time.
