Hyday MD vs Markdly

Hyday MD is a Markdown tool built for reading. Originally designed as the mobile reader for the Hyday note-taking app, it lets you comfortably read notes stored in iCloud Drive on your iPhone and iPad. It is also a general-purpose lightweight Markdown reader — any .md file written with other tools displays just fine. DESIGN PRINCIPLES • Hands off your syntax — your files stay untouched • Content first — the UI stays quietly in the background • Typography is the design — hierarchy through type and whitespace, not decoration FEATURES • Frontmatter parsing: title, type, tags, createdAt, and lastModified extracted and displayed automatically • Wiki links: [[note name]] jumps straight to the linked note; the back button returns to the previous one • Mermaid diagrams: flowcharts, sequence diagrams, and more rendered inline, with full-screen viewing • Reading font size: four levels (S / M / L / XL), independent of the system setting • Edit and write back: tap edit, make changes, save — lastModified updates in your local time zone • LaTeX math: inline and block syntax both supported • Code blocks: syntax highlighting, language labels, one-tap copy • Tables: GFM alignment syntax supported • Task lists: GFM checkboxes rendered in brand colors • Local images: paths resolved relative to the .md file • hyday-asset custom scheme: maps to the assets/ folder at the vault root • Hyday life log marks: start, end, now, idea, important — five states told apart by color • Subfolder browsing: only folders containing Markdown are shown, keeping lists clean • Recent files: jump back to your last-read note straight from the home screen • Recent folders: persisted with iOS security-scoped bookmarks — no re-picking after relaunch • Bundled fonts: Fira Sans Condensed and Fira Code, fully rendered even offline PRIVACY • No user data collected • No analytics, no tracking • No network requests (unless your files reference web images) • Recent files and folders lists live only on your device GOOD FOR • Writers, engineers, and researchers who keep Markdown notes • Hyday note app users • Anyone who reads technical docs, lecture notes, or study notes on their phone NOT FOR • Rich-text (WYSIWYG) editing • Team collaboration or cloud version control • Reading PDF, Word, or other formats

The markdown editor that respects your output. Markdly is a native Markdown editor for iPhone and iPad with live preview, built for people who write in plain .md and ship a real deliverable. Open a file, write, and watch the preview render as you type. The same Bravely Account unlocks Markdly on Mac, Windows, and Linux too, so the document you start on your phone is waiting on your desktop. WRITE & EDIT • Native SwiftUI editor with adjustable font size and syntax highlighting • Live preview with multiple themes, side by side • Mermaid diagrams render right inside the preview • KaTeX math, inline and block • Open .md, .markdown, .mdown, .mkd, and .mkdn files from anywhere DOCUMENT INTEGRATION • Open files from the Files app and from any Markdown share • Save back to iCloud Drive, Files, or any document provider • Multi-document tabs to switch between drafts • Recent files for one-tap return FOLDER-BASED, NO LOCK-IN Your files stay plain .md on disk — no vault, no proprietary format, nothing to migrate out of later. Git-friendly, and the same files open everywhere else you use Markdly. WHAT MARKD.LY IS FOR Blog posts. README files. Documentation. Technical writing. Markdly is for writing that lives in markdown but leaves the app as something polished — not a note-graph or a second brain. If you need wikilinks and a graph, use a vault tool. If you want documents that look great when you ship them, this is the editor. ONE PURCHASE, EVERY PLATFORM Markdly is a tool, not a service.
