Dawn is the calm, beautiful place to read Markdown on your iPhone. These days your AI assistant answers in Markdown — headings, lists, code, tables. On a phone, that usually shows up as a wall of raw symbols. Open it in Dawn and it becomes a page worth reading: clean margins, real hierarchy, a comfortable line length, and type set the way a good book is. And it isn't only AI. Your notes, your READMEs, your documents — any .md file reads beautifully here. No editing chrome, no clutter, just the words. WHAT DAWN RENDERS • Full CommonMark and GitHub Flavored Markdown • Syntax-highlighted code blocks that collapse out of the way • Tables that scroll sideways instead of breaking • Math, written in LaTeX and set with KaTeX • Diagrams, drawn from Mermaid • Task lists, nested quotes, footnotes, and frontmatter — folded into a tidy Properties strip BUILT FOR READING • Pinch to size the text exactly how you like it • Light, dark, and automatic themes • An outline you can open to jump between headings • A slim progress line so you always know where you are • A measured column width that keeps long lines easy on the eyes YOUR FILES, YOUR WAY • Open Markdown straight from the Files app or iCloud Drive • Send a web link from Safari and Dawn fetches and renders it • Recent documents group themselves by Today, Yesterday, and This Week • Pin the ones you keep coming back to, and search across names and contents SHARE BEAUTIFULLY Select any passage and share it as plain text, as Markdown, or as a polished image card with syntax highlighting — ready for Messages, X, or anywhere else. PRIVATE BY DESIGN No account, no sign-in, no tracking. Your files stay on your device, and nothing you read is sent anywhere. Everything renders on-device, so Dawn works with or without a connection. Requires iPhone with iOS 17 or later.
