Best Astronomy Apps 2026
Astronomy apps can help with sky viewing, object catalogs, learning, mission tracking, or telescope control. Compare catalog size and platform coverage, then consider whether AR sky view and offline access suit how and where you observe. Learning content and mission tracking offer other ways to explore the subject, while telescope control may matter for your equipment setup. Cosmic Watch, Night Sky, and Solar System Scope are among the apps shown. Free-plan availability and paid-from pricing add cost context as you compare capabilities. Focus on the features that match your interests, from identifying objects to following missions.
