Stellar Horizon

Discover the universe from your iOS device. With stunning imagery, real-time data, and interactive features, this app brings the wonders of space exploration straight into your hands.

SwiftUI SceneKit iOS Firebase NASA API Space Technology

The vision

Stellar Horizon turns your iOS device into a portal to the cosmos. The app combines state-of-the-art iOS technology with official space APIs from NASA, ESA, and other space agencies.

At the heart of the app is an interactive 3D Earth built with SceneKit that visualises historical climate data. Users can rotate the Earth in real time and explore different textures.

The ISS live tracker shows the current position of the International Space Station on a MapKit-based map and notifies users of upcoming flyovers at their location.

With the built-in astronomy gallery, users can browse breathtaking astrophotography, like images, and leave comments. A Space News Hub keeps them up to date with the latest developments in spaceflight.
