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.
Requirements: requires internet access
