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 extremely simple to use and has unique features that are ONLY found in this app. Just get into the path of the solar eclipse, and then with just 2 taps on your device, the app is ready to "talk" you through the eclipseI have observed 3 previous total solar eclipses overseas and I am a NASA Subject Matter Expert for the 2017 US total solar eclipse. This is the original and only "taking timer" for solar eclipses. The first version of this program was developed by me in 2002. 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 specifically 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. The help file also includes 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. This app is the "Crown Jewel" for solar eclipse observing. No App Ads. No In-App Purchases. You Get It All.
