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.
