Hello, I would like to contribute for adding the split screen support for the app. I appeal you to assign this issue to me.

The support for split screen is a bit tricky because of the orientation of the main activity with respect to the orientation of the accelerometers; I tried it some weeks ago and I chosen to not implement it at this time.
Anyway, thanks for your availability.

Ah! okay. Got that.
