Don't mind the bad reviews.
Yes you only get 4 letters. But what is the lite version for? It's to give the parent a taste before you spend $1 on the full version. I loaded the lite and it was good enough to upgrade to full version. If you are really going to 1 star this app because its limited, then you need to stop buying iPads for your toddler. Seriously, people spend so much money on their kids at toys r us, but $1 for an app is outrageous ... If this pertains to you, stop breeding.
