SoLuna

SoLuna is a utility for the iPhone and iPod touch that calculates moon phases as well as predicted sunrise, sunset, moonrise, and moonset times. It also calculates predictions for the begin and end of civil, nautical, and astronomical twilight. The current moon phase is shown at the top of the main screen, while the predicted dates for the next 4 major phases are shown along the bottom of the main screen. The rise, set and twilight data is in table form in the center of the screen. The current latitude and longitude that the program is using for calculations is displayed in decimal format at the bottom left of the main screen. SoLuna can use the built in location capabilities of the iPhone to determine your location, or you can set your location manually on the settings page. You can can also change the date on the settings page to calculate information for other dates.
