My opinion is that this application does need some polish. However, it really does work very well. My 8 year old and my 11 year old find it a treat to test on the iPad and see their % correct in real-time. I also enjoy the statistics and ease of deck entry on the laptop or iPad.
So, thank you very much for your hard work. I can see the ongoing effort that has gone into this product.
