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.

Verdict
The clearest difference is in-app purchases: Amavit Abacus at none against FlashAnzan's 1. Amavit Abacus also leads on iOS requirement (16.0 vs 18.0). FlashAnzan's advantage is update cadence (every 3 days vs every 2 weeks) and device support (4 vs 2). On price and ads there is nothing between them.
