Your app for solar eclipse 2017!

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.

Please keep in mind this is a CPU/GPU intensive app. Recommended for phones a tablets made within the last 2 years.

Excellent app, almost

It gave the circumstances accurately except for the totality countdown. For some reason, it was ~50 minutes late.
