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!

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!

    Ben Gilles Published date: August 22, 2017

    I thought this app was amazing. We used the times to really experience the event. I used this app with another app called "Sun Locator Lite" I mainly used the other app to get an AR view of the sun's path so I could set up my camera. If you could incorporate something like that into your app you will have an amazing eclipse app. One last thing I need to say TOTALITY! Full Review

    Stephanie Reynolds Published date: August 21, 2017

    Absolutely fantastic. This app made ALL the difference in knowing exactly when/how long we would experience totality. The timing was absurdly spot on. Absolutely perfect. Also told us when to check for shadow bands, which we would have otherwise missed under the assumption that they were supposed to have been visible at an earlier time. Love this app. Don't know what I would have done without it. 💖 Full Review

    I'd give it 1,000 stars if I could. I really wanted to thank you for making this amazing product! We happened to get stuck in an area with no cell service. The app told us everything we needed to know instantly. No need for guessing where we needed to be. All actuate down to the very second. We ended up avoiding nearly all traffic while still getting a great show. Priceless moment. Thanks! Full Review

    Perfect for the Eclipse today! The voice notifications were great, fantastic safety reminders, and everyone around me could hear it too. I hope it is still around in 2024 when the next eclipse rolls through the US. The only improvement I would suggest is maybe being able to click on the contact point for more info (such as it being the "diamond ring"). I never saw much in the Eclipse data page either... but I didn't spend much time there. Full Review

    No, this app isn't as slick as a lot of modern apps are, but it made our eclipse experience SO much better than it would have been without it. It literally talked us through each segment of the eclipse. It was great to have the audible cues so we could focus on observing the various eclipse events instead of looking at an app or other reference material. Thanks so much for making this available to the public! Full Review

    Karen Rogers Published date: August 21, 2017

    Genius! Talks (yes, really talks) you through the entire eclipse based on your local coordinates. Suggests times to take equally spaced photos. Tells you when to wear and remove glasses and when to look for shadow bands (snakes). Oh - and let's you do practice runs so you're fully prepared. Thanks to YouTube channel "Smarter Every Day" for recommending this app. Worth every penny. Addendum: We used the app today, (8/21/17) and really enjoyed it. The audible cues and countdown were helpful and actually exciting. Can't wait to use it again in 2024. Full Review

    Erik Duxstad Published date: August 21, 2017

    Just finished the 2017 eclipse on Aug. 21st using this app. Overall, this app was a pleasant experience, but there are a few things that prevented it from being a no brainer. First, the good things: The app was very helpful in keeping track of where you are in the totality band and how long totality would last. The talking cues where very helpful and kept one on track in the experience. However, the app really could do with a UI make over and possibly a more streamlined experience would help the app. Usability was fine, but there was definitely a lot of buttons to press! Another questionable aspect was the price. In its current state I am not sure if it is worth the two dollars. If you already know where and when the eclipse will be, than this app does not have alot to offer. Overall if you are traveling and need the info, I would recommend. Full Review

    Ryan Wheeler Published date: August 18, 2017

    If you're going to be in totality, this is what you want. You will have the times for various phases of the eclipse, and audible cues to keep you on track in the mesmerizing time that it will be. If you're debating if it's worth spending $1.99 on this, ask yourself - if I miss the shadow bands, or mistime something, or lose out on dark vision because I looked at a bright screen to check the time, would I spend $2 to get that experience back? This app is made with focus, attention to detail, and the desire to help you fully experience this event. You. Want. This. App. Full Review

    Robert Hoots Published date: August 21, 2017

    If you're NOT in the path of totality, skip this one. I was hoping to still be able to get first & last contact times as well as the peak partial eclipse time, but no luck. The app at least tells me first and last contact times, but I have to enter them into the timer manually. The peak time field is locked so I can't enter the most important time into the timer and it won't calculate it based on the other manually entered values. This app is a great idea, and I appreciate the amount of work that went into making it work, but maybe consider the hundreds of thousands of people who won't quite be in the ideal locations before the 2024 update.

    5000 stars. Made sure we kept our eyes safe without looking away a second early. Reminded us to look around at the other things, like temperature. Excellent! Thank you for this design and thank you to forgotten person who interviewed you and alerted me of its existence. Full Review

    I finally decided to buy this app after 2 days of arguing with myself over it. It probably would have been an awesome tool, had it not started pouring down rain 6 minutes before 1st contact and every minute after. :( it is more thought out than my plan to purchase and use it. Full Review

    BrazBlue Published date: August 21, 2017

    Thank you, this tool gave me an amazing experience. Hope to use it during the 2024 eclipse as well. App it built well. Sad people didn't take the time to calculate their contact times to make the app work for them. The app does all the work for you, you just have to actually do the preparation part of it. Expecting one click to make it work, it wasn't built to work in just one specific spot. Sorry you got to tell it where you are first. Full Review

    Jesse Tinajero Published date: August 21, 2017

    Great, worked for the eclipse. Told us when to look around for phenomenon. I did notice it was a little late to say when the shadow bands showed up and when temperature dropped, but it was very useful. Thank you so much for helping me have the best experience with the solar eclipse! Full Review

  • Solar Eclipse Timer
    Nicole Anderson Published date: August 21, 2017

    I so wanted to give this app 5 stars, but I can't. It was great for checking to make sure we were in the path of totality and checking the times. Despite the fact that the audio would sometimes double up, I was ok with that. But it all fell apart at the most important time. Countdown to full totality, great! But then that was it, no further sound, no warning for when to put our glasses back on, during those precious 2 min of totality I'm looking at my phone trying to figure out why the app wasn't telling us what to do anymore, which defeated the entire purpose. Not to mention we didn't put our glasses back on quite in time. Disappointed. Full Review

    Craig Bidstrup Published date: August 21, 2017

    I am currently standing in the path of totality and using GPS to get my current location (which gets the correct latitude and longitude). This darn app says the duration of totality is 0. I want my money back. Edit: I found the hidden button that makes things work. -1 start for the bad UI Full Review

    Jered Pasay Published date: August 21, 2017

    Didnt work at all. I had it open during the eclypse with the sound on and nothing. The directions didn't really relate to the interface. No countdown timers showed up. And whats with the adjust buttons for the contacts. Full Review

    Michelle Marble Halling Published date: August 21, 2017

    I was hoping this app would work even though I'm not in the path of totality. you'd think it would because most of us are not and could not travel there but I still want to be a part of the viewing. I'm at the 90-99% area. It should tell us what we could expect to see and when etc etc. Lame, don't get it if you're not exactly on the path Full Review

    Bryan Lynch Published date: August 21, 2017

    PERFECT! Watched the 8/21/17 eclipse today right in the center of the path of totallity in Turner, OR. 2:01 totality! I thought the voice prompts would be dumb, but it just goes to show what I know. They were AWESOME! We were all so excited to see the total eclipse with our eyes that we weren't able to really fidget with our phones. The voice prompts calling out "glasses on" and "glasses off" were a great reminder to us while our jaws were hanging open. Full Review

    Working great so far. Make sure to load gps location and read instructions if not working as expected Best money I have ever spent on an app. Worked perfectly. Awesome! Thank you so much! Full Review

  • Solar Eclipse Timer
    Brian Phipps Published date: August 21, 2017

    Worth more than the price! I bought this after recommendation from Destin at Smarter Every Day on YouTube. The most notable thing was the shift to C3. At the exact moment the countdown got to Zero, the totality ended. So precise, I was speechless. Great job to all involved. Full Review

  • Solar Eclipse Timer
    Rachel Stein Published date: August 21, 2017

    Disappointed. I feel like this app might work if you are in a city or closer to a cell tower, but it was pretty much a waste of money for me and my group. The time were quite off - close to a minute, which makes a big difference during an eclipse. It froze several times and showed a plain black screen. The interface is clunky. Also, the talking cues just plain didn't work for some reason. More trouble than it was worth. Full Review

    Stephen Gadberry Published date: August 21, 2017

    Perfectly on time. Put this full blast through my car during the eclipse at St. Clair in Missouri and a lot of people crowded around for the countdown timers and thanked me for having it. Pretty awesome app. Thanks! Full Review

  • Solar Eclipse Timer
    A.B. Carroll Published date: August 21, 2017

    Extremely disappointing. Unless you are in the path of totality, all it will do is calculate first contact time and THEN you have to manually enter it yourself into the timer. Feel ripped off! Full Review

  • Solar Eclipse Timer
    Paul Spiel Published date: August 21, 2017

    The app was less helpful than helpful. I was able to find a great location with it, but the app did not count down to totality, so we ended up missing the best part. It did count down to C1 and C3, but it didn't count down to C2. What a downer! Full Review

    Ross Whitehorne Published date: August 21, 2017

    Hook the app up to my Bluetooth so everyone around me could hear the contact times and every single one was spot-on in Lexington South Carolina at the parking at walmart. Hope I live to see the next eclipse and I hope this app works for that one as well great job on it. Full Review

    Elaine Seay Published date: August 21, 2017

    We are between third and fourth contact, the app worked great! We abandoned our watch due to SC heat. (We did not observe a significant ambient temperature change. LOL) My only complaint is that we could have used a voice reminder for pictures. I did not realize that we needed to write those out, and fiddling with equipment, etc., we would not have wanted to keep stopping to check a list. Otherwise, it worked great!!! Full Review

    For the 2017 solar eclipse, I was in the path of totality. While several events were happy around town, I opted to sit on my back porch. This app was perfect as it led me thru all phases with countdowns and observations. Wonderful experience made even better with this app. Thank you. Full Review

    Tommy Sears Published date: August 21, 2017

    I am 3.2 miles south of Carnesville, GA, most definitely in the path of totality and the eclipse is now partial and this thing says that I'm not in the path. Total ripoff. I had to keep watching and guesstimate for myself when the eclipse started because this thing says I'm outside the path --- wouldn't give me the start time. All of us in this area who downloaded this app deserve a refund. Full Review

    Christopher Whitlock Published date: August 16, 2017

    AMAZING APP!!! I will be traveling to the path of totality and I am so excited to use this app. It is obviously very well made, and I highly recommend it for the upcoming eclipse. It will prove to be an invaluable too as it takes the guess work out of the timing. I love it. Full Review

  • Solar Eclipse Timer
    Brock Jolet Published date: August 21, 2017

    The app worked well, but thankfully I planned ahead. I didn't have GPS or data signal where I watched, but I was able to manually type in the coordinates and all the times were perfectly accurate. However, it never spoke to me. I checked the settings and audio was on, but no sound during the eclipse. There is sound if you run the demo. Which reminds me of another quirk. If you practice with the demo, it erases your saved coordinates and times. Even if you save the eclipse through the app, there's no way to get that information back without typing in the coordinates again. Thankfully I caught this while I did have signal and prepared.

    If you followed the instructions, this app works WONDERFULLY. I was filming in a large group and this app sounded off exactly as I needed it to. The countdown to put glasses back on as totality ended was so precise, other people exclaimed. This DEFINITELY made the viewing experience safer. Follow the instructions!!!! Full Review

    This app was amazing. It made all the difference in my eclipse viewing! I wish I could give more than 5 stars. To everyone complaining about the app being "garbage" because you were not in totality. It says in like 10 different places that it's not that useful except in totality. I don't know what you were expecting. I wish it had a Google maps integration to help me find totality. Was kind of a pain to make sure I was in the totality band, but once O was this app worked great. Full Review

    Can't wait to use this app. I'll be taking care of my 2 year old son at the time, so anything to help keep track of events is going to be well worth it, and the audio cues sold me on this for that reason. (Smarter Every Day brought me here. Thanks Destin!!) Full Review
