Must have app for preschoolers

My son is 3.5 and the Bugs series are his favorite iPad games (Bugs and Buttons, Bug and Numbers, and Bug and Bubbles). I have sat down with him to teach him how to do all the mini games. This one has numbers involved so I say its for 3-4 year olds and up. There is a lot of counting, and it goes into measuring, clocks and stacking. Bugs and Buttons is the best app of the three to start your child on. Its easy to skip past a tougher mini game if your hold gets stuck. There is a wide variety of mini games and they all have an educational purpose (except for maybe roach racing which is just funny). Graphics are fantastic. A must have app for preschoolers.
