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.
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!
It gives detailed information about the eclipse at your location or any location. Great for scouting out locations to determine if trees or mountains will obstruct any part of the eclipse. The Azimuth/Altitude of each contact is extremely helpful. It isn't clear if the azimuth is referenced to true or magnetic north. I assume true, but if the app were explicit about this, it would remove any doubt.
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
This is an impressive app, and it's free! I could locate my address in the path of the totality and the app told me exactly what time the partial and the totality would start and end for my specific location. There are a number of learning and education resources included as well. This is definitely worth having.
I downloaded 5 "eclipse" apps and this was the only one that actually gave me the information I needed to know when I can see the eclipse at my location. The others are just full of generic information and provide no free customization. This is the one to get.
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!
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!
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.
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
Loved this app, it is perfect!! Such an amazing app, wish there was a reason to keep it. It took the guess work out of the eclipse, I had studied maps before and this made it easy!!! Thank you for creating it!!!!
This app will help you get to where you need to be for the eclipse. The only thing I would add is an option to show a standard map in addition to the satellite view. Great app by a great organization.
It’s a simple app that does what it says. There’s a nice interactive map that shows the duration of totality, and an image of what the eclipse will look like at totality for that site.
I've been downloading just about all the apps I could find about the solar eclipse. This one is one of the very best. Highly recommended, and it's free!
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?
Congratulations for a job WELL DONE! Great interactivity, precise map and location services, and superb concept and development. Far more than what I expected. Kudos! 👏🏻👏🏻
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?
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.
Big Kid Science, founded by astronomer Jeff Bennett, has produced lots of good astronomy education resources over the years. Their eclipse app, Totality, recently released in an updated version for the two eclipses crossing the US in the next six months, is one that should be in every eclipse chaser's toolkit. Totality's main feature is its ease of use. Dedicated eclipse chasers may want all the technical details in scientific jargon but the average family wanting to see nature's greatest spectacle just wants to know where to go, how to get there, and what to expect. Not that there isn't something in Totality for everyone. I found the unique feature that shows the closest point to the center line of annularity or totality to be fascinating. And it's handy for anyone wanting to get into the Moon's shadow by the quickest route. Once you choose the area, scouting potential viewing locations is as easy as it gets. Totality's interactive eclipse maps are based on code from Xavier Jubier's popular interactive Google Maps. The app provides directions to chosen locations by going straight to Google Maps. The details of the eclipse at the location, including timings and depth of the eclipse, along with simulations of what you'll see, are enough for anyone who doesn't require arcane details. And if you don't know C1 from C4, Totality can get you up to speed with explanations in simple, everyday language. To make a good thing even better, Totality is free to download and use, and free of ads. Big Kid Science has recently donated Totality to the American Astronomical Society to share it with a greater audience.
Partial eclipses near major cities are equally scientifically informative to educate family members. SF has 76% coverage for example. KQED.org has good radio interview with good advice on eye protection methods, like a pinhole projector card.
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).
