Sky Guide
What Sky Guide is
Sky Guide is a stargazing app from Fifth Star Labs LLC for iOS and macOS. Point a compatible device overhead to identify stars, constellations, planets, and satellites, or use augmented reality to place celestial figures over the real sky. Timed notifications can warn when the International Space Station is about to pass over your location. Cinematic time controls show past or future sky positions, and a personalized calendar lists location-filtered events such as solar and lunar eclipses. Sky Guide works with or without Wi-Fi, cellular service, or GPS, including offline use. It has a free plan, with in-app purchases for All Constellations at $1.99, paid once and PRO Lifetime at $249.99, paid once. Compatibility requires iOS 18 or later, iPadOS 18 or later, or macOS 13 or later on a Mac with Apple M1 or later. The App Store says coarse location, product interaction, and diagnostics data may be collected without linking it to identity.
