Description

The Solar Eclipse Timer app was developed by me, an expert eclipse chaser, to help people get the most enjoyment out of observing and photographing a total solar eclipse.

#1 ECLIPSE TIMING APP
It was the #1 eclipse timing app used during the 2017 total solar eclipse that crossed the United States. It was then used successfully in Chile and Argentina during the 2019 solar eclipse.

It was featured in Sky and Telescope Magazine in 2002, 2003 and 2017. Fred Espenak, Mr. Eclipse, used the app in 2017 and he recommended it on his blog. It’s been used by Destin Sandlin of the YouTube channel Smarter Every Day for his two eclipses, 2017 and 2019, and he recommends the app. From Space.com, Elizabeth Howell, gave it a positive review. Over 630 positive comments were posted after the 2017 eclipse.
The unique feature of the app is that it will automatically calculate your exact contact times when you are at your final observing position. Then, I become your personal eclipse astronomer, because though the app I will talk you through the eclipse!It is so easy to use! Basically a “Two Tap Setup”. Get into the path; 1 Tap to Geolocate. 2. Tap to Load the Contact Times. That’s it! You are now timing the eclipse!

FREE DOWNLOAD

The app is a FREE download to try it out. It then has in-app purchases to BUY the eclipse data set that you want to time. It is ready for 2020, 2021, 2023 and 2024.

The FREE download allows you to play with the app, see its features and realize its benefits for you on Eclipse Day. Watch a built-in app tutorial that explains all of the functions of the app.

WORKS IN REMOTE LOCATIONS
Solar Eclipse Timer will work anywhere. The app does its calculations internally. It does not require cell service or an internet connection to work. It only requires a GPS signal, or manually entering GPS coordinates for the calculations to occur.

OTHER BENEFITS AND FEATURESEclipse Education - When you use Solar Eclipse Timer, it is one part of my three-part program of eclipse education and preparation. This app is coordinated with my Solar Eclipse Timer YouTube channel and my Solar Eclipse Timer website. There is no other place in the world to get such a comprehensive eclipse preparation package! It’s like having me as your person solar eclipse coach.

Partial Eclipse Timing Mode - It can also time the eclipse as a partial eclipse if you are not in the path of totality. It displays your maximum percent coverage and then continuously displays the progress of the eclipse. The announcements are altered to be appropriate for your maximum eclipse percentage.

Extensive Help File – The Help File is a comprehensive guide not only to using the app but to learning about eclipses. Within the help file text are external hyperlinks to my YouTube channel videos about eclipse subjects. There are over 3 hours of custom eclipse video content including some of my original research on my YouTube channel.

This App Is Ad Free!

ALWAYS USE EYE PROTECTION DURING THE PARTIAL PHASES OF A SOLAR ECLIPSE! OR EVEN WHEN IT IS BRIGHT! NOT DOING SO CAN CAUSE EYE DAMAGE!

We are NOT liable for misuse of the app causing inaccurate timing or the lack of eye safety precautions during the observation of a solar eclipse.

The "glasses off" and "glasses on" statements are a guide based on the calculated contact times. The timing can be affected by your phone's clock and the shape of the shadow due to the edge of the lunar limb. Lunar limb adjustment times for every point on the path are available on the internet. You are responsible for the timing so use the Adjust buttons as necessary. Glasses should be ON if it's bright!

No voice, followed directions

Saw this on SmarterEveryDay, and used it for the 2017 eclipse in Oregon. Well done. But the voice never came on. I saw ticker tape messages, which were great, but despite following all instructions on my iPhone SE (mute off, volume up, all notifications enabled, this app only one running after restarting it) I got no voice prompts. The only thing I did that might (but shouldn't) have caused an issue was switching to camera and back to this app.

The word "Stop" does not look like a button, rather just plain title text, so it took me a long time to figure out I could tap it.

The main screen has to scroll (not obvious) so the critical Check Position button (which DOES look like a button unlike the Stop "button") is hidden off the bottom of the screen, so you just stair at the main screen wondering what to do with a dead timer app.

The "Check Position" button leads to another counterintuitive screen where you "Get My Location" (that sounds different than "check location") and "Calculate Contact Tines"). Why do I have to press these manually? Can't the contact times update automatically? It feels clunky, like Excel with auto calculate turned off. Further, I have to "Load Contact Times". Load from a disk drive? How about "apply" or "use"? The terminology on the page is a bit confusing.

I love the developer's engagement and contribution to science. I look forward to improvements, and of course 2024.

Thanks for your comment. You points are noted and I am making a list of things to do to improve the next version.

Great app, very accurate

Like many others, I saw the app and Dr Telepun with Destin on SED, and downloaded immediately. I didn't do a ton of advance work, but did familiarize myself with the functionality for thirty minutes and a few practice runs, and corrected the times for lunar limb profile at my location. I don't know how difficult that would be to integrate into the app, but allowing the calculation to occur as an option within the app would be nice -- although there are websites that do most of the heavy lifting on the calculation now anyway. On the day of the eclipse, I used a Bluetooth earbud to hear the vocal cues, and kept my eyes in the sky (and my kids). Great app, very accurate with the times once corrected -- which was very easy to do. Helpful verbal reminders, too.

I found the app very easy to use, and sufficiently comprehensive if a bit utilitarian. But as an engineer, utilitarian is as much a complement as comprehensive is. You might not confuse the GUI for a pretty Apple produced piece of software, but it's every bit as functional as one.

I was in Chile earlier this year -- and having an app like this at least makes me think about wanting to go back for the eclipse in 2019. Good work to the developer and team. Apps like this are the fantastic part about the smartphone world we live in.

Thank you for your thoughtful review! I am happy the app helped you with the eclipse! I will be updating the elements for the upcoming eclipses including Chile. I am happy that you did corrections for lunar limb adjustments, the vast majority of users would not. But I believe I have the only app out that there that even discusses it and then provides the adjust ability to the contact times to correct for it. I don't think I will be able to provide the function to have the times corrected automatically. Even Xavier Jubier, who has done extensive work on this subject does not include it in his bass calculations, he provides the data separately for those who want to adjust. I am beginning a list of things that I will do to improve the app in Version 2. Thanks again!

Awesome app!

We used this during the eclipse today just into the path of totality in SC. We didn't have an exact plan today, so being able to check our position was great. The built in announcements of when eclipse events were occurring were right on cue! We noticed temp changes, wildlife behaviors, and solar bands!

The only things I would change about this would be to have the choice for military time, as many people prefer not to use it. Also, I would like to see a digital countdown for each occurrence such as first contact, second contact... Another useful feature would be to know exactly what percentage of the eclipse you will see based on GPS location.

Another nice feature would be to know what percentage of the eclipse we are currently viewing during the eclipse. We would often look up and guesstimate about what percentage was covered and look around at the amount of light. It would be kinda of cool to know exactly what percentage of sunlight we were experiencing. It's crazy how much daylight the smallest sliver of sun can produce!

Again, amazing app with just a few convenience features missing. I'm looking forward to using it again in 2024!
