Star Walk 2 is an Android and iOS stargazing app for exploring a sky map and identifying objects in the sky. Planet Walk highlights planets and lets users switch between them, including Uranus and Neptune. Premium access adds deep-sky objects, comets, dwarf planets, asteroids, meteor showers, more than 10,000 satellites, interactive 3D models, and educational cartoons. The maker distinguishes two apps: Pro is paid and ad-free, while Plus is free and ad-supported; purchases do not transfer between them. Star Walk 2 Plus is listed at free. Other listed options are $0.99 a month for StarWalk2 Ads+ Monthly Premium, $5.99 a year for StarWalk2 Ads+ Yearly Premium, and $8.99, paid once for Night Sky View: No Ads. Some plans may be temporarily unavailable. An internet connection is needed for current satellite and comet path data, and satellite orbits are shown only a few days before and after the current date because they can change. The App Store listing requires iOS 15.0 or later.
