The abacus, reimagined.
Abacus4Everyone is a comprehensive, interactive online abacus learning platform designed for children ages 5 to 15. Our app teaches mental mathematics using the ancient abacus method, helping students develop extraordinary calculation speed and mental visualization skills.
The abacus (also known as soroban in Japanese or Indian abacus) has been used for centuries to develop mental arithmetic abilities. Research shows that children who learn abacus-based mental maths develop stronger number sense, improved concentration, better memory, and enhanced confidence in mathematics.

Our curriculum follows a structured belt system, similar to martial arts, that motivates students and provides clear progression milestones.
Practice with our digital abacus featuring clickable beads, automatic number display, and support for up to 19 rods. Students can visualize any number and practice bead movements.
Every formula and concept includes dedicated practice exercises and printable worksheets for home practice.
Teachers can register, create student accounts, track progress, assign homework, and manage their entire class from one dashboard.
Our levels map to internationally recognised soroban gradings, so progress here translates to the wider abacus world:
Mappings are indicative — formal kyu certification is administered by national soroban associations.
