The distribution mechanism is different. The Stories can't be hosted on the web but, you can embed them in the app itself and give people access to it with a dev mode flag.
This is if your components are in the app’s codebase itself and not in a shared components library. The workflow there gets a bit messy IMO since you probably need to then maintain an entirely separate RN app just for the storybook in that component library’s codebase, which leads to a decent amount of redundant work when upgrading RN versions.
