Sky Map

Point your phone at the sky

Sky Map turns an Android phone into a practical star chart. Aim the device upward and it uses location and orientation sensors to match the view with stars, planets, constellations, and other celestial objects. It suits beginners who want help identifying what they can see, as well as students and casual observers who need a quick reference outdoors.

Useful tools for learning

• Search for a named celestial object and follow on-screen guidance toward it.
• Change the viewing time to see where objects will appear at another point in the day or night.
• Filter the display by categories such as planets, constellations, and deep-sky objects.
• Use the map as a visual aid rather than relying on printed charts or memorized positions.

Simple, focused reference app

The interface is functional and easy to read in a dark setting, with controls built around toggles and direct navigation. It is not designed as a full astronomy course: its main strength is connecting a name and shape with the patch of sky in front of you. That makes it especially useful for first observations, family stargazing, and classroom demonstrations.

Scale and track record

Sky Map is published by Sky Map Devs in the Books & Reference category. Its rating is 4.085122 from 487,005 reviews, with 50,000,000+ installs. The project is open source, which gives technically minded users a clearer view of how the app is developed and makes it a notable choice for people who prefer a straightforward astronomy utility over a feature-heavy planetarium.
