The upcoming solar eclipse in August 21 bids to be more than a rare celestial event – it could meld the increasingly pervasive world of smartphone apps with a total eclipse visible from sea to shining sea.
At least 15 free apps that focus on the eclipse are available for Android phones, iPhones, or both. They'll help you find your way to spots where you can experience the eclipse from within the dark path of the moon's shadow, learn photography techniques, read about solar eclipses, connect to live-streamed telescope views, and more.
