Originally developed as Google Sky Map, it has now been donated and open sourced.
The Map doesn't move/points in the wrong place
Make sure you haven't switched into manual mode. Does your phone have a compass? If not, Sky Map cannot tell your orientation. Look it up here: http://www.gsmarena.com/
Try calibrating your compass by moving it in a figure of 8 motion or as described here
Are there any magnets or metal nearby that might interfere with the compass? Try switching off "magnetic correction" (in settings) and see if that is more accurate.
Why is autolocation not supported for my phone?
In Android 6 the way permissions work has changed. You need to enable the location permission setting for Sky Map as described here:
The Map is jittery
Try adjusting the sensor speed and damping (in settings). We have a better solution coming soon!
Do I need an internet connection?
No, but some functions (like entering your location manually) won't work without one. You'll have to use the GPS or enter a latitude and longitude instead.
Can I help test the latest features?
Sure! Join our beta testing program and get the latest version.

Planetarium In your Pocket
Sky Map is a planet and astronomy mapping application that helps users decipher the night’s sky.
Once the app is opened, the app locates the user’s location via GPS and a detailed map of the sky above them is displayed on their screen. The app displays stars, constellations, galaxies, and planets that are viewable from the users location.
If the user only wants planets or constellations displayed, they can use the apps filtering system to adjust what is shown on their screen making it easier to pinpoint the object they’re searching. If the user sees something in the night sky they want to identify, they can point their phone in that direction and the name of the planet or star will be displayed.
Search features allow the user to type in the name of a specific object and the screen will pull up the location with AN arrow directing the user which direction theY need to be looking. A cool “time-travel” feature allows the user to type in a specific date or historic moment in the past (i.e. Apollo 11 moon landing) and the app will show what the moon and the night sky looked like on that date.
Can view sky in automatic or manual mode
Visual is very shaky when it’s in automatic mode
For the amateur astronomer this is a pretty good app. The best features of the app are the ability to filter what is shown on your phone and the keyword search for a specific celestial object. The navigation is easy and the results are very detailed. You won’t be using this app on a nightly basis, but will come in handy when you get the astronomy itch.
