The app was developed by a maths teacher who wanted an interactive, game-like app that promoted maths skills. Players advance through levels based on abilities and each player has a choice of math difficulty, game difficulty and operation skills they want to develop. As well as the story mode, there is also a practice level. Player statistic detail achievements. Up to 5 player profiles can be stored.
What I liked about this app was that the game can be tailored to the user to provide choices of what math skill to work on while also making the learning fun.
This Youtube Video, created by the App Developer, explains a little bit more about the app.
A lite version of the app is available to try before buying.
