Summary
Star Chart is an astronomy app that uses GPS and a 3D universe model to identify what is visible when you point a device at the sky. Its catalogue maps over 20 million stars across both hemispheres and includes all 88 constellations, the solar system’s planets and moons, the Sun, and the 110-object Messier catalogue. The listing also says it tracks comets, meteor showers, and satellites live. For exploration, users can take guided tours, use voice control, and shift the view up to 10,000 years into the past or future. They can set a location anywhere on Earth, look below the horizon, and zoom into star fields. Normal use does not require an internet connection. Augmented reality mode requires a built-in compass, while manual scrolling is supported on all devices. Star Chart runs on Android, iOS, macOS, and Windows. Its free plan includes every feature and upgrade, with no subscriptions or paywalls; optional star sponsorship is available. The maker says it has been building the app since 2009.
