Cool Supan is a touch-based abacus designed to help users learn the basics of abacus calculation in an efficient and engaging way. Unlike traditional abacuses, users can move the beads by simply touching them, making it an enjoyable experience for learners of all ages. The app offers nine basic levels to learn how to use the abacus, including addition, subtraction, even numbers, odd numbers, complementary numbers, and more.

Once users have learned the basics, they can move on to unlimited training sessions for one, two, or three-digit addition and subtraction. The app also offers a menu to practice adding numbers from 1 to 100.

In addition to the training features, Cool Supan also includes helpful tools such as an explanation button that provides basic information about the abacus and each level, a "back" button to return to the previous position, and a "pass" button to create and solve problems. Plus, the app comes with a built-in timer to track progress and improve efficiency.

Overall, Cool Supan is an excellent tool for anyone interested in learning the abacus and improving their math skills.
