Même en demandant à changer le mot de passe (puisque ne s’ouvre pas avec le bon) je ne reçois pas le mail de réinitialisation. C’est très handicapant pour une méthode qui demande d’être remplie au jour le jour… ### 1/5 — Billings *2025-06-11* Estava utilizando o aplicativo normalmente mais de uma hora pra outra ele parou de funcionar já desinstalei e instalei novamente e nada de ele funcionar acabei ficando mais de dias sem anotar diariamente no que acaba dificultando, até pq é preciso eu fazer as anotações é um aplicativo bom mais tem deixado muito a desejar em relação a isso. ### 1/5 — Conta premium não atualiza *2024-11-19* Fiz a compra da assinatura anual ontem (18/11) do aplicativo e até o momento o aplicativo não atualizou. Hoje quando fui tentar exportar o gráfico apareceu “acesso a conta premium expirado” e esta me pedindo para comprar novamente. O valor da assinatura já foi debitado na minha fatura e não tenho acesso aos recursos premium. ### 3/5 — Instabilidade *2024-07-24* O aplicativo até funciona e facilita muito, acho muito mais prático anotar no celular do que em papel, porém, é instável, tem dois dias que não consigo entrar, já desinstalei e instalei para ver se resolve e não adiantou nada, não consigo nem entrar por computador. Espero melhoras no aplicativo. ### 5/5 — Sugerencia *2024-03-22* Muy buena aplicación, fácil y entendible. Me gustaría que se pudiera cargar la foto del matrimonio. ### 1/5 — Dificuldade para entrar no app!! *2024-02-02* Estou desde ontem (01/02/24) tentando acessar meu gráfico colocando os mesmos dados de usuário e senha de sempre e não consigo entrar!!! Pq esse app é tão ruim?? Melhor anotar no papel mesmo!!! ### 5/5 — Não consigo logar *2024-02-02* Gosto muito do aplicativo, mas nos últimos meses está dando erro ou não consigo logar. Coloco meu dados e nada acontece. Isto é ruim pois são informações importantes para a eficácia do método. ### 1/5 — Muito ruim! *2023-06-01* Coloca login e senha e não abre… aplicativo péssimo! ### 3/5 — Billings app premium *2023-02-10* Paguei pela versão prêmio e as opções não estão disponíveis para mim como enviar por e-mail pdf.
