Put recent and upcoming annular and total solar eclipses in your pocket with Totality by Big Kid Science, available FREE for iOS and Android smartphones! Totality is sponsored by the American Astronomical Society and includes the following features, among others:
- Interactive maps that show what you’ll see at any location in the Americas for the annular eclipse of October 14, 2023, and the total eclipse of April 8, 2024.
- Interactive maps of other recent and upcoming solar eclipses around the world. All maps are based on code by renowned eclipse expert Xavier Jubier.
- Using your phone's GPS, the app will tell you not only what you can see at your current location, but also will show the nearest location where you can witness annularity or totality. The app even ties to your phone's map tool to provide driving directions to the central line!
- Zoom, scroll, and tap to move around the map, get a table of eclipse circumstances at any location, or bring up additional details.
- Learn how, when, and why eclipses occur, as well as how to observe them safely.
And it's all FREE — with no ads — created as a public service by Big Kid Science and the American Astronomical Society.
