Armillary Sphere vs Eclipse Explorer

Armillary is a handy astronomical application for measurement and recording specific times, locations and movement of the Sun and the stars, based on a Ptolemaic model. With this app, we can easily determine the time and position of sunrise and sunset, the length of a day, the altitude of the sun at different times of the year and the position of celestial objects. This 3-dimensional Armillary app reconstructs the ancient armillary sphere with the help of modern technology. The ancient device, believed to be first invented around 200 B.C., had been in use for over 2,000 years in history. FEATURES • This modern-day counterpart can be displayed in any scale and rotated by any angle. • You can make desired measurements by making relevant adjustment of the “Meridian”, “Equator”, “Horizon”, “Ecliptic” and “Altitude” on the app. USER CONTROLS • Touch-screen rotation – Gently swipe or slide fingers for desired rotation of armillary sphere rings • Swipe-touch panel – Swipe fingers on the display panel for desired movement of armillary sphere rings • Pinch-to-zoom – Use index finger and the thumb in a pinch motion to enlarge or shrink the screen as desired.

Eclipse Explorer is a free mobile app that allows you to view the circumstances for solar eclipses that occur between 1900 and 2100 using your GPS defined location. It uniquely features countdown timers to eclipse events at your specific location, simulates the position of the Sun and Moon, and draws the location of the Moon's shadow on the Earth in real-time. A solar eclipse is one of nature's most amazing spectacles, however, clouds can ruin your day. Use this app to overlay satellite and radar data on the day of the eclipse to make sure you stay within the path of totality and away from the clouds! Find out exactly when the eclipse starts and finishes for your location with countdown timers. Be ready for the total eclipse in August of 2017! Free, with minor ad support. Only one full page ad will be displayed per app start, then one banner ad, which will automatically close in less than 20 seconds. Please check out my website for full details and instructions on how to use the app. http://www.solareclipseapp.com Please keep in mind this is a CPU/GPU intensive app. Recommended for phones a tablets made within the last 2 years.
