My Familiar is a native iOS developer tool that lets you run any of your Expo / React Native projects from GitHub on your phone, edit them inline by pinching to summon a Claude chat scoped to the screen you're looking at, and push the resulting diffs back to your repo.
The project is in early development. The source of truth is the OSS repo on GitHub; a maintainer-run TestFlight channel exists as a convenience install path for the author and a small invited group.
