LEARN SOROBAN: Japanese Abacus

Lucas Labs

About this app

Learn Soroban is your comprehensive guide to the traditional Japanese abacus method. This educational app teaches you how to use the physical Soroban and progressively transition to Anzan (mental calculation) by visualizing the beads in your mind.

WHAT IS THE SOROBAN? The Soroban is the Japanese version of the abacus, a powerful tool used for centuries to perform calculations with remarkable speed and accuracy. By mastering the bead movements, students develop a strong number sense and the ability to perform complex mental arithmetic (Anzan) without physical tools.

FEATURES

🧮 Complete Tutorial Mode Follow step-by-step instructions that break down operations into manageable movements. Watch the Soroban beads animate as you learn the logic behind every addition, subtraction, multiplication, and division. The app explains the essential fingering rules (Thumb for Earth beads, Index for Heaven beads) and the left-to-right calculation method.

Flash Anzan Mode Challenge your mental agility with Flash Anzan. In this mode, numbers appear and disappear quickly on the screen, forcing you to calculate mentally without seeing the static beads. Perfect for transitioning from the physical tool to pure visualization.

Practice & Training Train at your own pace with the interactive digital Soroban. Solve randomly generated problems and get immediate feedback to reinforce your muscle memory.

⚙️ Customizable Settings Tailor the difficulty to your skill level. Unlike rigid apps, Learn Soroban allows you to configure:

Number of digits (Left and Right operands)

Flash speed (time per number)

Interval between numbers

Specific operations (Addition, Subtraction, Multiplication, Division)

MULTILINGUAL SUPPORT Available in 11 languages: English, Portuguese, Spanish, French, German, Italian, Russian, Arabic, Japanese, Korean, and Chinese.

WHO IS THIS FOR? This app is designed for beginners and enthusiasts who want to:

Learn authentic Soroban techniques from scratch.

Understand the mechanics of Flash Anzan.

Improve mental calculation speed and concentration.

Challenge their brain with a proven educational method.

HOW IT WORKS The method focuses on the "image" of the beads. You learn to manipulate the Soroban physically (or digitally), and with practice, you internalize these movements to calculate mentally. Learn Soroban provides the structured path to achieve this skill.
