Star Chart
starchartapp.com
What it is
Star Chart uses GPS and a 3D model of the universe to identify what is visible when a device is pointed at the sky. Its catalogue maps over 20 million stars across both hemispheres, all 88 constellations, the planets and moons of the solar system, the Sun, and the 110-object Messier catalogue. The listing says comets, meteor showers, and satellites are tracked live. Exploration tools include guided tours, voice control, and a time shift of up to 10,000 years in either direction. Users 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; 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 listing describes it as a companion for curious children and amateur astronomers.
