Description

We've added new total solar eclipses for 2026, 2027, 2028, and 2030!

A total solar eclipse is among the most awe-inspiring events in nature, but few people have 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 eclipses and find your way to upcoming eclipses around the world, including the 2023 annular and 2024 total eclipses that will pass across North America.

Totality, your solar-eclipse companion, is sponsored by the nonprofit American Astronomical Society. Its awesome features include:

• An interactive map that shows exactly what you’ll see at any location in the world for upcoming annular and total solar eclipses, as well as a review of recent past eclipses. (Maps 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, as well as showing you the nearest locations where you can witness annularity or totality.
• The app offers navigation tools to help you find your best route to the path of totality.
• 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.

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).

Excellent Solar Eclipse App!

Having many un-fond memories of plotting the centerline and north & south limits of the July 11, 1991 & other total solar eclipses on photocopied paper maps, I was delighted when I discovered the Totality app a couple of months ago! The interactive eclipse track map in Totality is truly welcome. Plus, the map displays your current location, thus leaving no doubt as to your position relative to the centerline.

Kudos to the highly responsive developer who has today released version 4.0.1 which fixed an intermittent crashing-on-launch issue that the 4.0.0 version released 3 days ago had, so the app is solid & stable once again.

I highly recommend this easy to use (and free) app which is suitable for eclipse chasers of any level of experience.

Big Stars for Big Kid Science

I love the interactive map feature. The details of the map surpass other apps that I have looked at in preparation of the eclipse. I've even been able to use it to pinpoint the best spot on the lake to watch! I'm an elementary science lab teacher in KY where we have a path of totality nearby so I especially appreciate the tabs available to educate people about eclipses and the section on classroom activities. Ironically, I already had some of the exact activities in my lesson plans for the next couple of weeks. The free app is definitely worth taking the time to download in time for the eclipse even if you've waited until the last minute!

Great app that takes a couple minutes to warm up

Sometimes, the first time I use this app, there are no results when I pick my location. But after a couple minutes, it starts to work perfectly. I'm guessing that whatever server is doing the calculations goes to sleep and gets woken up. Amazing app. I love using it. I'm very excited for this Saturday and April 2024!
