Scissors tab at bottom blocks the bottom strings from being moved and you lose the level.
And can’t play on the plane without internet for the interminable ads!

If I have wifi I can download the next book in a series without using my computer. It crashes every hour or so, but starts back up. I like using iTunes on my computer to transfer the books to my iPhone better. It doesn't crash and all my stuff is in one place. But when traveling without my computer the audible app has come on handy at times.

The banners advertising the pay version are too distracting. I got it for my kids and the banners will do them in. I'm deleting the app and not buying the pay version. Save your time.
