Plodiac is a Star and Planet Viewer.
The Stars shine at their proper magnitudes, and are connected to outline the constellations. The planets are properly positioned; updated at startup to the current date and time. The Sun is at the center of the view and has been replaced by the current Zodiac Sign.
Tapping the screen reveals three options. There is a Zodiac Symbols reference page which includes the starting Astrological dates. There is also a Planet Symbols reference page. The third option rotates the view 180-degrees to view the night sky opposite the Sun. Further, this flat-map image of the constellations can be dynamically moved by the user.
The view can be returned to the Sun-view to complete the 360-degree tour of the Zodiac Constellations. To save the sky-views for special occasions, like the birth of a child, just use the built-in iPhone feature to take a snap-shot of the screen and set the image as your background.
