O Memo usa uma abordagem baseada em cartões de memória para ajudá-lo a praticar os assuntos de seu interesse em programação. Temos um conjunto original de coleções que vão desde os tópicos de programação mais básicos aos mais avançados. Cada coleção possui muitos recursos úteis e selecionados a mão que permitirão que você se aprofunde nos assuntos que deseja. Você pode registrar como se sentiu a cada Memo que responde e nós vamos registrar esses dados para lembrá-lo quando algum assunto precisa de prática. A partir desses processos, o aplicativo aprende seu comportamento e, usando nosso algoritmo de curva de esquecimento, Memo identifica quando é melhor mostrar um assunto específico novamente. Todo o aplicativo foi construído pela comunidade, para a comunidade. Quer fazer uma contribuição? Vá para o nosso Github

Verdict

The call

The clearest difference is in-app purchases: Memo at none against Learning Java's 4. Memo also leads on iOS requirement (12.0 vs 15.0). Learning Java's advantage is update cadence (every 2 weeks vs every 18 months) and review sentiment (100% vs 82%). On price, ads, monetization model and device support there is nothing between them.
