Annoying rate me nag screen

Shows an annoying "rate me" nag screen on every start. I rated now to get rid of it and i rated one star just because of this. Remove the screen or let it occur only once and i promise to rate 5 stars. Dont like to admit this under the circumstances, but the app is actually awesome.
