What Star Chart is
Star Chart is an astronomy and stargazing app for identifying the night sky and exploring the solar system. It uses GPS and a 3D 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 work by 17th-century astronomer Johannes Hevelius. On AR-capable mobile devices, users can view the sky through augmented reality. A separate VR version simulates exploration from the Sun to Pluto; the Cardboard version requires a Cardboard viewer. Star Chart is available on Android, iOS, macOS, and Windows, and supports offline access and learning content. The free version costs nothing and includes in-app upgrades. Escapist Games develops and publishes games for smartphones, tablets, and consoles, and provides contact details on its website for feedback and feature requests.
