This is a PHP web app to display the current Moon sign along with a daily forecast for each moon position. It updates automatically and uses the Swiss Ephemeris to get an accurate position of the Moon. I originally made this as a website widget, but I have modified it to work as an app for iPhone, iPad, and iPod and other mobile devices. It’s available for free.
This app is also viewable (but not optimized) on other mobile devices with web capability.
This is also available as a WordPress widget.
Requirements: requires internet access
