FOR TEACHERS - Homework, done fast: assign to a whole group or a single student, set a schedule, and let the app check the work automatically. - Progress tracking: see individual and group results in real time, and know exactly who needs help. - Group management: run both group lessons and one-on-one work. - Student motivation: achievements and practice streaks keep learners coming back. - Less admin, more teaching: the routine work is handled for you, so you spend your time on instruction. FOR STUDENTS Children complete the homework you assign and practice freely through focused, playful games built around abacus (soroban) technique: - Addition and subtraction with Small Friends and Big Friends (UCMAS-standard methods) - Anzan (mental calculation), flashcards, and flash tests - Multiplication and division - Achievements and streaks that keep practice rewarding FOR PARENTS Parents follow along with clear, automatic progress updates and always know what their child is working on.

Practice flash anzan (flash mental arithmetic) in the same format as the Japanese grading examβ€”and climb the ranks. GRADED MODE (30 RANKS, KYU 10 TO DAN 20) Each rank uses the exam's total-time format: numbers flash within a fixed total time, you answer 10 problems, and 70 points is a pass. YOUR GRADE IS KEPT Your best rank is recorded on the device and in iCloud, so it follows you to a new device. ANSWER BY VOICE Type on the number pad, or just say the answer. Speech recognition runs entirely on your deviceβ€”your voice is never sent anywhere. CUSTOM PRACTICE Set digits, count, and display time yourselfβ€”from slow single digits to 3-digit numbers at 0.3 seconds. IPHONE DUO Big numbers when it's open; fold it in half and the question sits above with the number keys below. Close it and keep practicing on the outer screen. IPHONE, IPAD AND MAC Works on iPhone, iPad and Mac, and your grade follows you between them through iCloud. No ads. Available in nine languages: English, Japanese, Chinese (Simplified and Traditional), Korean, German, Spanish, French and Brazilian Portuguese. Note: This app is not affiliated with or endorsed by any certification body.
