Okay I have purchased the Cabelas Recon App for the iPhone. Features include gps mapping, ballistics info, maps much like google earth, a neat blood trail feature, moon phase info (but does not show major/minor periods...just phases, sunrise/sunset etc), compass. You can use it to keep a journal and even load videos and pics into different functions. I'm sure I'm missing some things but so far I'm pretty impressed with it. IMO it would be complete if it had peak hunting times (major and minor moon info). Well worth the $5.99 IMO.
