Still is not random. Very nice app otherwise.
Test it for yourself: create a test wheel with wedges 0-9. Give it a spin and see where it lands, say on 6. Then tap the center button 3 times and viola, it will almost always land on 6. When it does land on another number its slightly on either side of 6- on 5 or 7. The same goes for spinning with a finger. If you use consistent timing and force with your spin it will land in the same area with only slight variation, not randomness.
