SoroboomAR is an Android game that offers a range of interactive mental arithmetic trainers in 3D format. Its main goal is to help children use the app to benefit their brains by developing and activating their mental abilities. The improved Soroban mental arithmetic used in all the games of the app is aimed at the synchronous development of a child's brain. These techniques are not taught in regular schools, and useful non-standard thinking skills can be honed daily at a convenient time on favorite gadgets.

In addition to the mental arithmetic trainers, the app also features a 3D trainer for learning the counting methodology and an augmented reality mode. Now, Grandpa Soroban can come to life and take on various forms. Complete the homework and get a new augmented reality card.

• Children studying at the Soroban oral counting school

• Schoolchildren who want to maintain their intellectual abilities and speed counting skills
• Elderly people who want to maintain mental clarity and productivity in life
