We only have the free version but my 2year old son loves it. Im waiting until hes a little older to buy it so he doesnt get tired of it. I like how eventually the letters start to look like the kids handwriting. Its not just reference points as one user "pointed out" on the paid versions reviews- it evolves as your child learns the letters and numbers.
