Do NOT even try with iPad3/Retina
As the others say, this newer version will not work, nor will it upgrade from the older version - so it will be stuck forever in your updates waiting to be upgraded... The earlier version worked fine, and there are plenty of other apps loaded here that work without issue. I will probably start deleting these programs that get stuck in the update cycle...EDIT: Had to uninstall due to stuck update cycle...shame.
