Bom

Tem um excelente potencial, mas precisa melhorar a fluidez do app e ser mais intuitivo

Response from developer

Muito obrigado por acreditar no potencial do Cogni. Gostaríamos muito de entender melhor o que podemos tornar mais fluido e intuitivo. Se puder, envie suas sugestões para support@cognifly.net. Teremos prazer em conversar com você.

Equipe atenciosa e aplicativo bom

Estou gostando bastante do Cogni. O suporte é muito atencioso e responde rapidamente, resolvendo os problemas com prontidão. Tive uma dificuldade com a importação de baralhos no formato apkg e a equipe conseguiu solucionar essa questão.

Além disso, precisei de ajuda para recuperar alguns cursos que haviam sido apagados e o suporte resolveu tudo rapidamente.

Estou satisfeita com o aplicativo e o atendimento da equipe!

Response from developer

Olá, Olívia. Agradecemos por atualizar sua avaliação e compartilhar sua experiência. Ficamos muito felizes em saber que conseguimos resolver tanto o problema com a importação do arquivo APKG quanto a recuperação dos cursos excluídos. Obrigado pela confiança e pelas palavras gentis sobre nosso atendimento. Sempre que precisar, estaremos à disposição.

Produto enganoso

Antes mesmo de fazer cadastro já aparece a opção de cobrança mensal, anual e vitalício num valor de 49,90 e quando você ver no cartão, você pagou 299,90
Naymê PereiraNaymê Pereira

Response from developer

Olá, Naymé. O preço de 49,99 exibido no app para o acesso vitalício está em dólares americanos (US$), não em reais. Antes de qualquer cobrança, a App Store mostra uma tela de confirmação com o valor final em reais. A compra só é concluída depois que você confirma esse valor. Vamos deixar a moeda mais clara também na tela do app. Obrigado por apontar esse problema.
