A total solar eclipse is among the most awe-inspiring events in nature, but most people have never had the opportunity to experience one. Totality by Big Kid Science, a FREE educational app now owned by the nonprofit American Astronomical Society, aims to help change that by helping you learn about solar eclipses and find your way to upcoming total solar eclipses around the world through the year 2050.

Totality, your solar-eclipse companion, includes these awesome features:

• Interactive maps that show exactly what you’ll see at any location in the world for upcoming total solar eclipses, as well as a review of recent ones. (Maps are based on eclipse code graciously provided by Xavier Jubier.)
• Using your phone's GPS, the app will tell you what you'll see for these eclipses at your current location, if anything, and show the nearest locations where you can witness totality.
• The app offers navigation tools to help you find your best route to the path of totality (when driving is possible).
• The Learn screen offers options that will help you learn how to view a solar eclipse safely, help you understand the science behind eclipses, and much more. It even includes a set of classroom activities.
• The Shop screen offers fantastic books about space and science (including a children’s book designed to accompany the app), eclipse glasses for safe viewing (which you can use to look at the Sun at any time, not just during an eclipse), and links to some of our favorite space education nonprofits.
• An updated User Guide and numerous improvements to the app’s functionality.

And it's all absolutely free, including no ads, brought to you as a public service by Big Kid Science and the American Astronomical Society.

Totality by Big Kid Science is now available in English, Spanish, French, and Portuguese (determined by the language setting on your device).

Great. Simple interface, most useful information (totality time, etc.) right up front. Easily interfaces with maps for driving directions. One improvement I would have liked was if it showed current location when the app opened.

LOVE THIS! MADE OUR ECLIPSE EXPERIENCE GREAT!!! Downloaded as a suggestion from the planetarium we visited. Used and opened it SO MANY times to figure out where we wanted to be, times, etc. Thank you for making this FANTASTIC and FREE app! It made our Eclipse travels SO much better!!!

Totality saved the day! Throughout the day I was providing screenshots and directions to friends and relatives who lived along the path of totality. It was accurate right down the second. It worked flawlessly.

It's a bit late for a review to do you much good, but this app is (was) great. You could have found your house on a Google map and get excellent forecast of what you will see (could have seen) and when. Why the review? Because a great app like this deserves recognition for the developers. Yeah team!!

Norman H

Superb. It was great to have an app that could tell you the length of totality for any map location you wish to consider.

Diego Vargas

This was great I found a perfect sight to watch totality with my family, I gave myself a bunch of options to find the sight because the weather was iffy and it I didn't want to chance it

This is a great app- simple and intuitive, but with all the information needed needed to enjoy the 2024 eclipse! I'm a former astronomer and studied solar eclipses in school. I'm currently an eclipse ambassador, providing outreach to the public in Knoxville, TN. I'm recommending this app to EVERYONE.
