NightSkyBook

About

NightSkyBook is a calm field guide for casual stargazing. Plan a clear-night session, learn what to look for in the sky, and keep a private observing log without an account. Use Tonight to prepare a simple field plan before you step outside. Browse the Atlas for constellations, planets, bright objects, nebulae, galaxies, meteor showers, and practical viewing notes. Save observations with location text, conditions, object notes, and what you actually saw. NightSkyBook Pro unlocks unlimited sky-coach questions and unlimited observing-log depth for people who observe often. The free app remains useful for browsing the guide and trying the core workflow. NightSkyBook is intentionally honest about scope: it is not a live AR sky map, weather service, telescope controller, or precision ephemeris engine. It is a local-first astronomy companion for learning the night sky and recording real observations. This app offers an auto-renewable subscription (monthly or yearly). Payment is charged to your Apple Account at confirmation of purchase. It renews automatically unless turned off at least 24 hours before the end of the current period; manage or cancel in your Apple Account settings.
