Very nice application for kids from 4 to 9 years. Supports nine languages: English, Spanish, Russian, French, Italian, German, Serbian, Croatian and Macedonian. Nice and interesting way of learning letters and math. Older children may use this app for learning some foreign language. When writing or do the simple math, kid gets points for their efforts. For the math operations they can even compete with each other and get themselves in the top score list. Minimal recommended device screen size is 5". Let them learn and play!
