My 2-year-old loves this app, and we would definitely buy the full version, if it worked, but her favorite part, the puzzles, have a number of bugs. Sometimes puzzle pieces are missing, and she’s unable to finish the puzzle. Sometimes the pieces don’t move as they’re supposed to, and she can’t get them where they need to be. (I can’t, either.) If she is able to complete the puzzle, there’s no button to get back out of it, so I have to quit the app and relaunch it before she can do anything else in the app. Lastly, not a bug but just an annoyance, when you open the app, you just get to a home screen where you need to click a button to get to all the games and features. The button isn’t obvious, and even after watching me do it many, many times, she usually needs me to find the button for her, so she can use the app. Basically, this app requires A LOT of work from a parent and often ends in frustration, anyway. Don’t show it to your toddler! I tried this app on 2 iPads and 1 iPhone, and all of them had the same flaws.
