The app is OK and the kids love it. There is a lot of nonsensical urban legends around this series of apps, but I agree with some other reviews. Adds are OK, but they should filter potentially dangerous ads for kids, and something than it's also dangerous is the gateway to Youtube. My kid's tabled doesn't even have access to browser or the youtube app, but somehow they can see the videos there. The first video is OK and related to the app, but from there they can easily access unfiltered youtube content, and for some reason all recommended videos are no kid friendly (siren head, sonic.exe). I think that should be removed or patched somehow to avoid kids accessing Youtube. That breaks the entire point of having a tablet specially configured for kids. the same applied to the entire series of apps.
