Practice flash anzan (flash mental arithmetic) in the same format as the Japanese grading exam—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 device—your voice is never sent anywhere. CUSTOM PRACTICE Set digits, count, and display time yourself—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.

Treine seu cérebro como num dojo japonês. Zanki é um treinador de cálculo mental inspirado no Anzan — a arte japonesa de calcular com um ábaco imaginário. Números piscam na tela, um de cada vez, e você calcula tudo mentalmente. Simples de aprender, viciante de dominar. SISTEMA DE FAIXAS KYUU/DAN Progrida por 11 níveis, do 10º Kyuu (somas de 1 dígito) até o 1º Dan (operações mistas de 4 dígitos a 150ms por número). Cada faixa aumenta a velocidade, a quantidade e a complexidade dos números. TREINO FLASH Números aparecem em sequência no ritmo do seu nível. Sem papel, sem calculadora — só a sua mente. Feedback sonoro e tátil a cada rodada. MODO INICIANTE Começando no soroban mental? O Modo iniciante gera apenas operações com movimentos diretos de contas, sem complementos — perfeito para construir a base do ábaco mental. SEQUÊNCIA DIÁRIA Mantenha seu streak treinando todo dia. Acompanhe sua evolução com gráficos de precisão e histórico completo de sessões. TREINO PERSONALIZADO Ajuste dígitos, quantidade de parcelas, velocidade e rodadas para criar o treino perfeito para o seu nível. Treine 5 minutos por dia. Suba de faixa. Surpreenda-se com a velocidade da sua mente.
