## Totality by Big Kid Science Description
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).

## Totality by Big Kid Science Reviews in United States

### *---- "What happened to the app"
Can you fix the bugs bc I can’t see the percent of the eclipse and the time
-- Zack Selvidge, 2024-05-31

### ***** "Excellent App and worked great on April 8!"
This app is essential when you are traveling for a solar eclipse.  I recommended it to friends and coworkers to use and everyone really thought it was effective.  Hopefully there can be an app developed for lunar eclipses too!  Nicely done!
-- Andy from Delaware, 2024-04-09

### ***** "Very happy with this app!"
It was a little difficult finding my location on the map but probably in a bad location. But we found it finally, the clouds parted the timing was spot in and we saw an awesome sight! Thanks!
-- Newton45, 2024-04-09

### ***-- "Very nice app.  Timing accuracy?"
Very useful app. A detail - the timing prediction of the start/end of totality was different by a few minutes from what I understood to be “correct”. Is it possible that your delta T needs to updated?
-- dccnd5, 2024-04-09

### ***** "Perfect for 4/8/2024"
Easy to use app with no ads or data collected (read their privacy policy) that provides a better service than what the NSO website provides with real time location relative to the eclipse path. Why can't all apps be like this?
-- ian.lewis, 2024-04-08

### ***** "Super easy to use"
Overlay of eclipse timing to google maps. Exactly what I was looking for. Free! Thank you.
-- R Peters, 2024-04-05

### *---- "Ok in the beginning"
When I first downloaded it for last year, it was absolutely amazing. I have done every update that they have put out but ever since the first update it’s glitchy it will not show your location even if you manually put it in it says it is not available this app was worth it in the beginning, but I would highly not recommend it
-- Dreamlincoln, 2024-03-26

### ***** "This is the best app"
It’s so good no adds so fun perfect for the eclipse it show where to go and where it is and the best thing is that when you don’t know where your house is you can just search it up on there and other places so yea everyone should get this app for sure
-- Hehfbhdhsjd, 2024-03-22

### ***** "Version 4.0.0 Crashes"
This new 2026 Eclipse version crashes on launch. IPhone 13 Pro IOS 17.4. Please fix. Focus on the 2024 Eclipse. You could have waited until April 9th to release this version but no lets screw up the 2024 version a month before the eclipse. Unbelievable.
Update 3/20/24
The app now appears to be working as before. Credit to the developer for the response and timely fix.
-- RWinTex, 2024-03-20

### ***** "Amazing App!"
I’ve been using this app for years now! It’s incredibly intuitive, user friendly, and informative. I strongly recommend this as your app for all things eclipse related.
-- jmsnegus, 2024-03-16
