In their own words
Star Chart
Star Chart is an astronomy app for viewing the night sky and exploring the solar system. It uses GPS and a three-dimensional universe model to calculate the real-time positions of stars and planets visible from Earth. Its guide includes all 88 constellations, with artwork based on the work of 17th-century astronomer Johannes Hevelius. On AR-capable mobile devices, an augmented-reality view overlays the sky in the user’s surroundings. A separate VR version simulates exploration of the solar system from the Sun to Pluto; the Cardboard version requires a Cardboard viewer. Star Chart is available for Android, iOS, macOS, and Windows, and supports offline access. The free edition includes in-app upgrades. Escapist Games develops and publishes games for smartphones, tablets, and consoles, and provides contact details for feedback and feature requests.
