E querem cobrar por esse lixo de app ### 1/5 — Horrível *2026-07-21* Esse é o pior app que eu já vi. A estética até parece boa e ele promete ser útil, mas simplesmente não deixa você entrar no aplicativo para ver as informações. A todo momento aparece uma tela mandando você pagar, e nem tem um “X” para fechar e continuar usando. Eu daria zero estrelas, mas não tem essa opção. Horrível! ### 3/5 — Bom mas não pude usar *2026-07-21* Vi um vídeo no tiktok e resolvi testar, mas tinha que paga.
