Turn your tablet into a TV, with this well designed video viewer, designed specifically for PBS Kids content. You can either watch WHYY live, or play one of the 34 channels.

The menu lets you tap the picture of the main character from each show, so no reading is required. When the video is playing, you can easily skip ahead or pause, rewind or skip to the next episode. You can toggle closed captioning on/off. Note that you'll need a live Internet connection, and that this app can use a lot of data (not unlike any video viewing app).
