Solar Eclipse Timer 4+

Thanks for your support in 2024! Updating the app for 2026 is being evaluated.

The Solar Eclipse Timer app was developed by me, an expert eclipse chaser and eclipse educator, to help people get the most enjoyment out of observing and photographing a total solar eclipse. It's a free download to test and learn the features with an in-app purchase of only $1.99 to buy the 2024 eclipse. Equal to the cost of a single pair of eclipse glasses and just as important!

The app's unique feature is that it announces the countdowns to the contact times out loud. It makes announcements to remind you to observe interesting eclipse phenomena like temperature changes, lighting changes, animal behavior, shadow bands, umbra approach, and more. It tells you when it is safe to take your glasses off and when to put them back on. There are spoken reminders for the MAX eclipse, looking for planets and stars, and observing the horizon. You won't miss a thing because I become your personal eclipse astronomer, talking 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! The app geolocates to find your position in the path and then calculates your precise contact times. It does not require internet access to do this. You are now timing the eclipse with me as your personal astronomer guide!

In collaboration with Fred Espenak (Mr. Eclipse), there is a new feature for 2024 called Photographer's Mode. In this mode, all spoken announcements are about the eclipse timing relative to the contact times. There are only three other essential reminders: two remove your solar filters, max eclipse, and replace solar filters. This mode was designed specifically for eclipse photographers.

#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 used successfully for solar eclipses in 2019, 2020, 2021, and, most recently, 2023, in Australia. It was featured in Sky and Telescope Magazine in 2002, 2003, 2017, and 2022.

WORKS IN REMOTE LOCATIONS
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.

I PROVIDE THE TWO BEST TOOLS FOR ECLIPSE PREPARATION!
The Solar Eclipse Timer app is coordinated with my solar eclipse preparation book, "Eclipse Day - 2024 and More! How to enjoy, observe, and photograph a total solar eclipse." This unique book has its chapters organized by the progression of the eclipse on eclipse day, and the chapters also follow the sequence of announcements by the app. See my website, www.solareclipsetimer.com, for more information about the book.

OTHER FEATURES
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 shows the progress of the eclipse. The announcements are altered to be appropriate for your maximum eclipse percentage.

This app Is Ad Free! This app DOES NOT track user data in any form.

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 guides 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. Use the Adjust buttons for Lunar Limb variation times adjustments. Glasses should be ON if it's bright!
