Stellarium Mobile Sky Map goes all the way back to 2001 when a French programmer named Fabien Chereau launched the desktop version. This app is unique because of its age. It has a catalog of 600,000 stars that are displayed on a real-time sky map. You can also zoom into the sky to see the stars and planets better.
