I bought this check out stand for my grandson 3 years ago, when he was 2.  He loved it then, piling all the food into the shopping cart.  I taught him how to scan the food and to watch them go down the conveyor belt and drop into the bag.  I immediately down loaded the app and was extremely impressed with all that it does, age groups and games to choose.  My grandson is almost 5 and he still loves it.  He asks me for my IPAD and he gets busy right away.  What I like best is it grows with the child.
