A free program for Android, by Alma.

This game is based on the educational strategy used by Jean Piaget, who believes that children learn best when they have fun, and also when they are guided by an adult.

This app uses a very simple and intuitive method to help children learn. It also helps them retain what they have learned, by playing a matching game with cards that have a related image and sound.

The main advantage of this app is that it uses the positive reinforcement technique, which is very effective with children. This means that, as the child plays the game, he will receive positive feedback, which will increase his confidence and motivation.

The app also has a very simple and intuitive interface, which makes it very easy to use.
