One path

A single track to your published app

This is the first Mission in the Galaxies.dev universe. Not just a one-off course, a bootcamp-like experience at a fraction of the cost.

Learn React Native

React Native recently released groundbreaking new architecture. We teach this new world so you have up-to-date skills.

Ship Your First App

Expo is the official recommended framework by Meta. We bring you vetted tutorials from the companies building the languages themselves.

Beat the Curve on your CV

Be ready when more companies adopt React Native to ship apps and learn mobile development to land the job.

Built to be Affordable

One small lifetime payment feels much more manageable than most bootcamps while giving you the same level of skills.
