Gesture control app (low battery consumption)

Hey guys, I've a D855 with Sense 7 installed and I really enjoy it, but I miss the gesture controles of nova... What you guys think is the best gesture control app, that is also a very good power efficient one.

In nova, I had the gesture controles built in, and now I will have to have a different app and I'm afraid it will affect much the battery life.

What you guys think?



Thanks in advance!
