Has life become so distracting that you don't even know how to concentrate anymore? Exercise and strengthen your concentration with Math Marathon. As an added bonus, you will surely improve your arithmetic skills.

Math Marathon tests and strengthens your concentration by generating addition or multiplication problems until you give an incorrect answer.

Besides the Marathon mode, a Warm Up mode can be chosen. The Warm Up mode generates sets of 10 problems, and offers the possibility to correct mistakes.

You can choose between three difficulty levels (basic, advanced, expert), characterized by the maximum magnitude and the signs of the numbers involved. Version 2.0 offers an additional Kids level.

Your best eight scores, per game and per difficulty level, are stored.

In the Marathon mode, the App guards against taking breaks by imposing a 1-minute time limit for each problem.

The App is designed around a smart keyboard, whose subtle color changes clarify its functionality.
