Solar Eclipse Timing Tool!

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.
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, 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!


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.

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!


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!

What's new in version 3.0

2017 and 2019 eclipse data sets are available in the FREE download in Test Mode. Delta T value adjustments.
