    Description
    Smart Planetarium is an astronomy app for Symbian smartphones which has almost the same capabilities as Google-Skymap. It shows all stars up to a magnitude of 5.0 and the positions of the sun, the moon and the planets. If you switch on the GPS and step up to a star, the app will show the sky in that direction. If you hold the screen of the smartphone against the sky, the acceleration sensors in the phone will position the star in the midst of the display.
