Are there any Daniel Tiger, SuperWhy or Caillou fans out there? My nephew loves watching Daniel Tiger, and now he can take the TV shows with him on the go. PlayKids is a subscription app that allows videos from these shows and more to be downloaded to a device for use when offline. This app is even more than that, though, with classic books, lullabies and games as well. Loads of fun on the go. Don't leave home without this app.
