  • “Trial version — Não gostei que ja te obriga a aceitar uma inscrição paga desde o início.”
  • “if you ask for a review before the paywall you get 1 star — Did the developers think the app would be so bad but so bad that after answering too many questions they thought: we better ask what people think now. Not after they used the app once.”
  • “Horrivel — Aplicativo não disponibiliza livres por completo conforme eu pensei no início, as frases são rasas e parecem feitas por IA, e a pior parte é que agora ficam enviando emails sem parar e não da pra cancelar a inscrição… Arrependimento enorme”
• Poor content quality and AI-generated text
