Baseball Training Apps for iPhone/android

Hey all...What do you think about baseball training apps for your smart phone?  There are a handful out there that have some quality information on them or a really neat user interface for very cheap.  I decided to create my own iPhone app for baseball to help my followers (i.e. youth coaches, dad coaches and players) understand and practice the fundamentals of baseball movements.  It is called My Coach: Baseball Instructor and is available on the app store.  The link is http://goo.gl/4cuLC or search on the app store.  I would love to hear feedback from fellow baseball players and coaches as I am continuing to work on it to make it better.  If you are interested in reviewing it, let me know and I will send you a free download...or just download it from the app store.
