A free app for Android, by KiDEO.

Preschool Adventures-1 is an educational app for children aged 3 to 4. It is packed with puzzles – 36 in total, in fact – which were designed with the aim of developing the cognitive abilities of your child.

The aforementioned 36 puzzles are divided into four, visually enticing sections. Each one of these should be teeming with adventures, games, and activities that are specifically mapped for cognitive development.

Some of the basic topics included in the plan are: numbers, animals, colors, geometric shapes, electrical appliances. Most of these come with sounds, so that your child not only associates the audio signature to the correct visual form as early as preschool, but also so that the learning process is so much more engaging.
