We've updated Skyclock for iOS 11, thanks to continued work on the project by our great team. Seeing your app come up as Ready for Sale in the App Store is a great feeling.
And thank you Skyclock users!
This version eliminates the in-app upgrade. Now, when you download Skyclock you'll get the full capabilities of the app without paying extra: Sun Zenith Time, and Sunrise, Sunset, Civil Twilight text messages at the top of the screen.
If you haven't yet, check us out on the App Store and Google Play. Skyclock is the definitive Sun and Twilight Calculator.
