Soroban: Mental Math Abacus is an iPhone and iPad app for Japanese abacus arithmetic and mental math practice. The app is designed around short, repeatable practice sessions that help learners move from bead movement and place value into faster arithmetic fluency and anzan-style mental calculation.
Instead of being a broad homework app, Soroban focuses on one clear learning habit: structured daily practice with an interactive virtual abacus, guided lessons, speed drills, Flash Anzan, workbook-style exercises, and private progress tracking. It supports English, Japanese, and Simplified Chinese, so learners and families can use it across common language settings.
Key Features
Interactive virtual abacus: Learners can practice bead movement and place-value reasoning directly on iPhone or iPad.
Guided lessons: Step-by-step material helps beginners understand soroban basics before moving into more confident arithmetic practice.
Flash Anzan: Learners can train visual memory and mental calculation by seeing numbers quickly and solving without relying only on written work.
Speed drills and daily challenges: Short practice modes help learners build accuracy and rhythm without needing a long study session.
Workbook-style practice: The app includes structured exercises for repeated arithmetic practice, making it useful alongside schoolwork, tutoring, homeschool routines, or independent study.
Smart practice and progress tracking: Private progress information helps learners see consistency and improvement over time.
Homework scanning: The app includes AI-powered homework scanning and insights so learners can connect app practice with real math work.
Use Cases
Students can use Soroban for focused daily arithmetic fluency practice, especially when they are learning place value, addition, subtraction, multiplication, division, or mental calculation strategies.
Parents and homeschool families can use it as a 5-10 minute math habit that is more structured than a generic calculator or free-play math game.
Self-learners can use it to understand soroban concepts, practice anzan, and build speed through repeatable drills on a mobile device.
Teachers and tutors can recommend it as a supplemental practice tool when learners need more repetition with mental arithmetic and number visualization.
Getting Started
Download Soroban from the App Store, open the guided lessons, and begin with the virtual abacus basics. Learners can then add short Flash Anzan sessions, speed drills, daily challenges, and workbook practice as they become more comfortable.
