The text features chrome-like metallic lettering with rainbow gradients, characteristic of 1980s synthwave aesthetic. Above the text is a glowing curved arc with horizontal lines. The design includes a perspective grid at the bottom and twinkling stars scattered throughout, creating a classic retrowave/synthwave visual style.

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.

React's logo, consisting of a light blue atomic symbol with orbiting electrons, is displayed over a black iPhone mockup shown at an angle. It has a dark, minimalist aesthetic with the phone appearing to float in a starry space-like background.

Learn React Native

React Native recently released groundbreaking new architecture and made it the default. We teach this new world so you have up-to-date skills and can run with the modern speed of development.

Ship Your First iOS & Android App

Expo is the official recommended framework by Meta. I’ve collaborated with their team to bring you vetted tutorials from the companies building the languages themselves.

Beat the Curve on your CV

It’s our bet that React Native is going for version 1.0 this year. Be ready when more companies adopt it to ship apps and learn mobile development to land the job.

Built to be Affordable

We hope that $35 feels much more manageable than most bootcamps or CS degrees while giving you the same level of skills.

Access all of Galaxies

When you buy Your First Launch, you also get access to all of Galaxies fast-paced courses, practical projects, tutorials, and more.

Co-Founder Platik

I've been able to go from zero mobile development experience to building an app for my startup ready for beta release in 3 months with Galaxies. Galaxies is some of the best software engineering learning content I've come across in my ten years of engineering experience. The content is practical and always engaging. I am extremely glad I managed to find Galaxies when I was first researching mobile technologies several months ago.
