The app's home screen, which opens in a full-screen, horizontal format only, will make your jaw drop. It's a time piece unlike any we've seen before on our phones. The clock face is built in the ecliptic, around planet Earth. It's what your view would be if you were floating about in outer space, watching the planets in orbit, with Earth as your focal point.

You get various viewing options to play with and play you will. You can view the Earth with or without the sky cover, with or without the constellations; you can view it as a contained celestial sphere, or even as an open sky that coats your entire screen with interstellar gas and dust - it's simply breathtaking, and the various combinations lead to fascinating results.

Twirl the globe on any axis and view the sky along with the position of the Sun, Moon and planets over any city, along with the time of day there in real time. The beauty of this lies in observing how darkness falls upon the cities as that part of the globe rotates away from the Sun.
