Important: This app is intended for education and design assistance. Always verify calculations, component ratings, circuit requirements, and safety considerations before building or operating electronic equipment.

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.
