After we had some problems with our initial version of GRush resulting in a rejection from the iTunes store we reworked our new sibling and uploaded it again for review. If everything works fine this time we expect GRush to hit the store around March, 12th 2014.
Basically Apple asked us to remove some functionality that was against their policies. As this was not known in advance, we aimed too high and shot too far. Maybe we can reintroduce this functionality at a later time when Apple is relieving their view on this matter.
