This is a PHP web app that displays the current positions of the planets in space according to the Swiss Ephemeris. It also notifies if a planet is in apparent “Retrograde” motion. The positions update automatically every 2 minutes. It’s available free for iPhone, iPod, iPad, and as a WordPress widget.
This app is also viewable (but not optimized) on other mobile devices with web capability. (See the link below for “Installation instructions iPhone, iPod, iPad, and other mobile devices”)
