## What it is
Sky Map (formerly Google Sky Map) is an open-source Android astronomy app that identifies stars, planets, and constellations by pointing your phone at the sky. Originally launched by Google in 2009 and open-sourced in 2012, it is now maintained by the original developers as a community project.

## Use cases
- identify stars and constellations by pointing my phone at the night sky
- find planets visible tonight from my location
- open source planetarium app for android
- learn astronomy with a sky viewing app
- locate celestial objects using my phone's sensors
- stargazing companion app for beginners

## When to choose
- you want a free, open-source sky map on Android
- you need a lightweight stargazing app available on F-Droid without tracking
- you want a simple, community-maintained astronomy tool with a long history

## When to avoid
- you need an iOS or desktop planetarium app
- you want a modern UI with advanced telescope control or deep-sky catalogs
- you need offline high-precision astronomy calculations
