Pick the symptom - the matching free tool is one click away.
Stellarium Mobile is the best all-around starting point for most iPhone and iPad users who want to identify objects and explore the sky. Choose SkySafari if you want more advanced observing tools or telescope control. For beginners, Star Walk 2 and Sky Tonight are worth considering; Sky Guide and Night Sky are Apple-platform alternatives. The right choice depends on whether you want quick identification, event planning, offline use, a deep catalog, or mount control.
