New App! Know Abacus

Our new app, Know Abacus, is just released on Apple© App Store℠ and Google© Play.  Yes, on Android platform too.

It continues on developing your children math skill.  Using Abacus, they can learn how to add and subtract numbers.  By imaging abacus and doing math in their head, they can use both the sides (left and right) of the brain together.  All feedback are welcome.
