Sky Map

What Sky Map does

Sky Map turns an Android phone into a point-and-identify guide to the night sky. Point the device upward and it uses the phone’s location and orientation sensors to label visible stars, planets and constellations. It suits beginners who want help recognizing what they can see, as well as casual astronomy learners who need a quick reference outdoors.

Useful reference tools

The app includes search and directional guidance for locating specific celestial objects. Its time controls can show how the sky changes, while viewing filters let users focus on categories such as planets, constellations or deep-sky objects. These tools make it more practical than a static star chart, particularly when the user already has a target in mind.

Simple, focused design

Sky Map keeps its presentation functional rather than decorative. The main experience centers on the live sky view, with straightforward controls for changing what is displayed. That approach works well in a dark outdoor setting, though users looking for a highly polished or modern interface may find it utilitarian. It is primarily an identification and navigation aid, not a detailed astronomy textbook.

Ratings in context

Sky Map has a 4.09 rating from 487,005 reviews and an install range of 50,000,000+. The large review volume gives that score more weight than a high rating based on only a small number of opinions. Developed by Sky Map Devs, it is listed in Books & Reference and has the reach of a widely used astronomy utility rather than a niche experiment.
