**This app requires Android Wear devices**

A watch face for Interstellar travellers, created under the supervision of Newton Science Magazine.

As your speed of travel accelerates towards the speed of light, Einstein’s special law of relativity causes time to begin slowing down. Interstellar Watch Face calculates the delay and tells you the time back on the earth.

From the menu page, you can choose from five speeds of travel: 99%, 99.9%, 99.99%, 99.999% and 99.9999% of the speed of light. The bottom right of the display shows how much faster time is moving on earth, which will range from seven to 707 times depending on the speed of travel you have chosen. The bottom left of the display shows which celestial objects you are approaching, and your distance from the earth.

Let yourself drift through space on your interstellar trip!
