Calcular, mental maths app for iPhone and iPad

With calcular, your children (and yourself) can finally practice mental math in the most efficient and fun way possible.

The app tells you calculations aloud, and you have to respond out loud within the time limit. The app automatically recognizes your voice, and provides you with the correct answer when needed. Give the right answers in a row to win!

It is possible to customize your level, from the easiest to the expert level, and to select operations you wish to concentrate upon.

Unlike the written method, this method requires your children to internalize mental maths visualization, and will allow them to progress independently. For adults, calcular also gives the opportunity to practice mental math at a pretty advanced level.
