This self described award winning app (CES 2010) is very simple and basic; it sings "the wheels on the bus" and has roughly 10 interactive screens that move the song along. The singing itself is very well done. The hook is the basic UX gestures that allow the child to interact with each screen. The interaction consists of 1 to 3 items per screen, so don't expect anything mind-blowing here. But this simplicity is what helps keep this app entertaining and engaging for the kid. His favorite screens are:

The doors on the bus: 'swiping' them open reveals a bird which squeaks when 'tapped'.

Fish on the bus (didn't know that verse): the bubbles from the fish pop when 'tapped', the fish leaps out of the bowl when 'tapped', and lastly the crab makes some clicking noises when 'tapped'.

Some of the screens are a bit weak but overall this app not only sounds great and allows for participatory singing but also allows the child to learn basic gestures and have fun while doing it. Great starter app for any child. Solid and stable. The HD version is $1.99.
