Was about to suggest this as well. But be careful, I'm not sure, but I think this app might cause mini-lags where the game freezes for a second. I removed this app (but removed other apps at the same time as well so might not be), and it seems to be gone. @Si had the same issue and suggested this to me. my 2 centsThis app will let you compare your times to others.
