Solar Eclipse Timer

By Gordon Telepun

This app is only available on the App Store for iOS devices.

Description

ONLY Useful If You Are Going To The PATH Of TOTALITY!! Solar Eclipse Timer is your smart phone guide for a total solar eclipse. It's like having your own personal astronomer help you on Eclipse Day! It is simple to use and has many unique features! Just get into the path of totality for the solar eclipse, and then with just 2 taps on your device, the app is ready to "talk" you through the eclipse. (NOTE: It's NOT useful in an area with only a partial eclipse. It's for people getting to the path of totality)

I have observed 3 previous total solar eclipses overseas and I am doing public out reach for the 2017 US total solar eclipse. Being based on my personal experience with eclipse observing and photography, I know exactly what is helpful when observing a total solar eclipse.

Created for first-time eclipse observers as well as veteran eclipse chasers, it is released in time to prepare everyone for the August 21, 2017 Total Solar Eclipse. This will be a once in a lifetime opportunity for many people and Solar Eclipse Timer is an inexpensive tool to ensure that you don't miss a second of this wonderful event!

GPS location functions automatically find your location, then the app calculates your contact times and max eclipse. With one tap it loads the 4 eclipse contact times into the timers. This function does not require an internet connection, the formula is located in the app itself!

These are all the unique features in this app:
Voice countdowns guide you precisely to the contact times. Announcements are made at the proper times to tell you to observe for interesting things during the partial phases, such as the temperature drop, lighting changes, animal behavior and shadow bands. The app also tells you when it is safe to take your solar glasses off and then when you must put them back on. To practice your plan for photography, the app has a demo session that plays a totality movie synchronized with the timers. The app includes a unique calculator that lists the times you use to take a sequence of partial phase images that creates a beautiful sequence of the phases just like the professional photographers! Although not a mapping program, included are internet hyperlinks to interactive maps of the eclipse path to help guide you to totality.
The app includes an extensive help file detailing the use of all of its unique features as well as eclipse day checklists and educational information about the partial phase phenomena.

Download the app, get yourself into the path of totality, tap a few buttons and sit back and let Solar Eclipse Timer "talk" you through this spectacular celestial event! It's an experience you will never forget!

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. You are responsible the timing. Glasses should be ON if it's bright!

Customer Reviews

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.

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.

Fantastic app!

I got this app after watching Smarter Every Day. I am so glad I did! After locking in my GPS coordinates, it took care of all of the alerts for me as well as the 20 or so people standing nearby as we were watching the eclipse.

A couple of notes for the developer:
1) the timing seemed to be slow by about 2-3 seconds. Meaning that totality through my glasses seemed to begin about 2-3 seconds before the app announced it. I know my coordinates were good but I am also fully aware that the clock on my phone could have been off or that my own perception could have been off. In any case, I'd rather leave my glasses on for a couple of extra seconds than take them off and burn my eyes!

2) Man, it took me a while to figure out how to use the app. I saw the extensive read me file but it took a second watching of the Smarter Every Day video to figure out the "dummy" 2 step process. Maybe for 2024 the app could come with a quick how-to video. That explains the features and use.

All in all a fantastic app that completely transformed my viewing experience and kept me informed about what was going on without requiring me to ever look away from the action! Well done, developer!
