Best educational app ever includes free customer support!

This app is almost too good to be true; its easily worth twice this price. We homeschool our 11 year old son and purchased this app because of its audio components so that our son can learn correct pronunciation. For kids learning new vocabulary, hearing correct pronunciation really is essential. Both my son and I are very visual learners and the interesting picture aids are extremely helpful.
We now use this app as our 6th graders complete vocabulary curriculum which supplements his language arts program and aids in his writing assignments (he gets extra credit if he includes a vocab word from the list hes working on in his paper). Its so much fun that I plan to use it when Im waiting at the doctors office or running errands.
I cant recommend this app highly enough. And oh, did I mention that a native English speaking tech support person located in Palo Alto, actually called me and helped me adjust my iPads settings correctly when I had a problem? Since when does a ten dollar app come with free awesome tech support?! Unbelievable.
