The calculations for events are accurate to a few minutes of the US Naval Observatory sun and moon calendars, and it doesn't rely on large astronomical data updates, nor on-line sites.
AVIA Moonrise is an application that presents an accurate moon phase and the official sunrise, sunset, moonrise, and moonset times for any place on Earth and for any date between Jan 1,1900 and Dec 31, 2099.
- all algorithms have been updated to include the latest modifications, and verified against the US Naval Observatory and major astronomy sites.
The application instantly shows the appearance and events for your iPhone's current location, and you can quickly check any location in the world using the map view.
In fact, it never accesses the Internet! This avoids any roaming charges from your operator.
Perfect for fishing or hunting trips, or astronomers and astrologers.
If you use the map function, you naturally need to have internet access.
