O Fluent Markdown lê seu arquivo Markdown e o publica como uma página de leitura elegante, ou como uma apresentação em tela cheia. Tudo no seu aparelho. LEIA EM SILÊNCIO. APRESENTE COM BELEZA. O mesmo documento vira uma página tipográfica para leitura longa, ou uma sequência de cenas editoriais em tela cheia, com rolagem vertical. O seu Markdown nunca muda. • Leitura: tipografia generosa, sumário navegável e a posição lembrada entre apps. • Apresentação: cenas, não slides. A estrutura do texto vira ritmo: títulos, evidências, citações. NOS DETALHES • Diagramas, offline: fluxogramas Mermaid são desenhados no aparelho, sem rede e sem serviço. • Estilos que servem ao texto: Editorial, Noite, Areia e Planta. O seu Markdown segue sendo a fonte da verdade. • Compartilhe o que criou: exporte a página ou uma única cena em HTML, PDF, Markdown ou PNG. • Uma biblioteca de papel: coleções, favoritos e busca por título e conteúdo. • Retome de onde parou: continue a leitura com progresso e modo salvos. PRIVADO POR CONSTRUÇÃO Suas palavras ficam no seu aparelho. Sem servidor. Sem conta. Sem modelo no meio do caminho. Só um arquivo e uma página. Interpretação e diagramação acontecem localmente, o app funciona offline e nada sai do aparelho. FLUENT MARKDOWN PRO Leitura e edição seguem grátis. O Fluent Markdown Pro é uma compra única, sem assinatura, que libera documentos ilimitados na biblioteca. Requer iOS ou iPadOS 26.

Verdict

The call

The clearest difference is in-app purchases: RC Markdown at none against Fluent Markdown's 1. RC Markdown also leads on iOS requirement (17.0 vs 26.0). Fluent Markdown's advantage is ads (none vs shown). On price and device support there is nothing between them.
