Merry Christmas! The full version of Kids Vehicles: City Trucks & Buses for the iPhone or iPad is FREE today as a gift from the developer 🙂 Jeff, the truck driver, teaches kids about 10 different vehicles. Included are: a school bus with an opening door, a dump truck with working bed, an ambulance with siren & horn, a concrete mixer with a revolving drum, a fire truck with a siren, horn, working ladder and more! Kids just tap on a part of the vehicle and Jeff identifies it. Then they can tap on Jeff for more details. I did find a minor glitch with the transit bus. When you tap on its roof, Jeff talks about a the roof of a school bus – obviously, this is not a major issue. If your child is a truck lover, you may want to take advantage of this gift.
