Share My Creation TIME MACHINE and Twin Paradox (Relativity Theory simulation)

hello! I did this app:
https://play.google.com/store/apps/details?id=com.Time.Machine
It is an educational free app

What app do?

The apparent (it isn't) paradox arising from relativity theory that if one of a pair of twins makes a long journey at near light speed and then returns, he will have aged less than the twin who remains behind.
Infact, the app simulates a relativistic environment where two observers, as in the "twin paradox" synchronize their clocks and one of them goes on a round trip, while the other waits on Earth.
The app show the space view of traveler.

thanks and will check it..
I would suggest that you increase the contrast between the off and the on colors of the segments of the digital alpha-numeric displays.. like making the off segment black and the background lite gray.. will make it more readable.

Beja, I solved the display contrast. Thanks for suggestion.
