Kani Math: Abacus Mental Math

Kani Math teaches mental arithmetic the way it has been taught for centuries — on the abacus. Your child moves soroban beads on screen until the shape of every number is familiar, then calculates without them.

WHY THE BEADS COME FIRST
On a soroban, a number is not a symbol. It is a position. A child who has moved the beads a few hundred times stops reading digits and starts seeing arrangements — and can then add, subtract, multiply and divide on a bead frame that exists only in their head. That is what mental arithmetic training actually is. It is not a gift a child either has or does not have. It is a mental image, and it is built by short, correctly ordered daily practice.

WHAT YOUR CHILD DOES
• Levels — the guided path. A short lesson, then drills, then a final exam, with history kept for every skill.
• Virtual Abacus, Abacus Lab and Abacus Drill — practice on a real soroban, timed target matching, and problems worked out on the beads.
• Mental Drill — flash anzan. Numbers appear and vanish while your child holds the running total. Answer by tapping, or switch on shout mode and say it out loud while the app listens (microphone and speech recognition permission required).
• Four timed ladders — Flash Sprint, Abacus Sprint, Column Sprint and Math Sprint. Read flashing numbers, read beads, work out a written column, or answer as many questions as possible before the clock runs out.
• Times Tables — study, quiz, timed and missing-factor modes, until they are automatic.
• Competition — a full contest paper: pick a category, 200 questions, eight minutes, marked category by category.
• Anzan Exam and Flash Exam — ranked practice papers from 10 kyu to dan and 31 flash levels, in order.
• Versus and Boss Battle — the same math, played against another player or the computer. Beating someone is a better reason to practice than a progress bar.
• Leaderboards, badges, streaks, and coins to spend in the Prize Shop. The streak is the reason to open the app again tomorrow.

THE LADDER
Foundation, Basic, Elementary A and B, Intermediate A and B, Higher A and B, and the Grand Level. Nothing unlocks until the rung below it is passed, so no skill arrives before the one it depends on.

Placement is by skill, never by age. A placement check suggests where to start, and you can set the level yourself at any time — a seven-year-old who has done this before and a ten-year-old who has not both begin exactly where they belong.

FOR PARENTS
With Premium, a parent view lives inside the app, with no second account to create: practice minutes, current streak, skill-by-skill progress and recent activity. Set a weekly goal and read the report. Homework from your child's teacher appears on the Class page — no sign-up needed. With Premium, several children can share one tablet, each with their own profile and their own progress.

LANGUAGES
The interface is available in 42 languages, including full right-to-left support for Arabic, Persian, Urdu and Kurdish. Lesson text is currently written in English.

DAILY PRACTICE AND PREMIUM
Each day includes a set amount of practice — drills, versus matches and level cards — which refreshes the following day. Kani Math Premium is an optional auto-renewing subscription that lifts those daily limits. It renews until cancelled, and you can manage or cancel it in Google Play at any time.

A few focused minutes most days is the whole method. Made for school-age learners, set up and supervised by a parent or teacher.
