Worth the purchase!
Response from developer
Hi, The app contains several different items FOR EACH of the vehicles. Different kinds of trains, different kinds of ships, different airplanes and different cars. This feature lets the toddler understand that there are vehicles which share the same name. The same goes for all the other apps: different kinds of animals, different kinds fish and different kinds musical instruments. Hope you like that app now that you realize that it has indeed 50 videos. Thank you.
