Flash Mental Math (Anzan)

Precise timing, 20 Kyu to Dan

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

A flash anzan trainer built around precise timing. The numbers keep an exact rhythm and the sound lands with them, so even at high speed you can keep your mind on the calculation. THREE THINGS ABOUT THIS APP Precise display and sound The moment each number appears is worked out from the time since the start, on every frame, so the spacing never drifts however many numbers there are. The sound plays at the same moment the number changes. From 20 Kyu to 20 Dan, step by step You start with 2 one-digit numbers and work up as the count grows and the time shrinks. Test Mode puts you through the same 40 grades as the abacus, from 20 Kyu to 20 Dan. Ten questions, seven right to pass. Compete with your class Set the same Room ID and you see a ranking of just that room. A soroban class or a family can share one Room ID and keep practising against people they know. There is a global ranking too. MAIN FEATURES Stages 1 to 6 digits, 350 steps per digit, 2,100 in all. The count of numbers and the speed change little by little. Test Mode 40 grades from 20 Kyu to 20 Dan. Ten questions a round, seven right to pass. Grades you pass are recorded. From 20 Kyu to 17 Kyu the first number appears as abacus beads. Rankings Five rankings: stages cleared, test grade, attempts, login streak and total logins. Global and room, both. No account and no sign-in. You can change your display name and Room ID in the settings. Custom Mode (monthly plan) Choose the digits, the count of numbers, the seconds and how many questions run back to back. Digits 1 to 7, numbers 2 to 30, seconds in steps of 0.1, and 1 to 30 questions. Display settings Four text colours and two fonts. Light and dark modes. Login streak Counts the days you keep coming back, and the total. You can compare those in the rankings too. WHO IT IS FOR • People learning at a soroban class who want to practise flash anzan at home • People who want grades to aim at while they practise • Teachers who want their students practising on the same terms • Adults who want to work their head FREE AND THE MONTHLY PLAN All 2,100 stages, Test Mode and the rankings are free. The monthly plan removes the ads and unlocks Custom Mode. QUESTIONS Do I need an account? No. Open it and practise. A display name is given to you and you can change it in the settings. What age is it for? Once you can add numbers. It starts at 2 one-digit numbers in 4 seconds. Can a soroban class use it? Yes. Set the same Room ID and the ranking covers just that class. Can I practise multiplication or division? No. This app is addition only. LANGUAGES Japanese, English, Chinese (Simplified), Korean, Spanish, Portuguese, French, German and Italian.
