What can I do with Sky Map?

Sky Map enables users to identify stars and planets by pointing their devices towards these objects in the sky. Sky Map automatically adjusts to identify on the device's screen the objects it is facing. Users can zoom in and out, and switch various layers such as constellations, planets, grids, and deep sky objects, on and off, choosing to make these elements visible or not. Users can also determine the locations of planets and stars relative to their own current locations with the search function. Inputting the name of a planet or star will direct users towards this object. A user may also explore the cosmos manually and move through the sky by touching the screen instead of having it adjust automatically.

Does Sky Map use the device's camera to determine what you see on the screen?

No, Sky Map does not make use of the camera.

Does Sky Map work during the daytime?

Can I use Sky Map to help orient myself by searching for Polaris (the North Star)?

Is it possible to search for constellations named after astrological signs (Aquarius, Capricorn, etc)?

Troubleshooting

The app stops tracking the stars.

It's possible your phone is in Manual mode. When you tap the screen, a button appears in the bottom right corner. This button will toggle between Automatic and Manual mode. Tap the button until you see the message "Switching to automatic mode." At that point, the application should perform normally.
