About this app

Enter your location or acquire your coordinates with GPS and enjoy a precisely simulated starry sky in all its glory, including twinkling stars and the band of the Milky Way.
SmartStellar also supports phone sensors which center the simulated sky on the position at which the phone is pointed to the real sky (augmented reality).
Alongside numerous celestial objects, SmartStellar provides realistic views of the planets, constellation figures, solar and lunar eclipses, etc.
