Hyday MD vs Levity Markdown Notes

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

Levity is a fast Markdown editor for your own plain-text notes, based on a folder in iCloud Drive or on your device. No account, no proprietary database, no separate sync service to set up. Point Levity at a folder and it mirrors every Markdown file inside it, and keeps mirroring as they change. Built for speed on your phone and read-compatible with Obsidian vaults. Levity opens, scrolls, and searches instantly, even in a large vault. It's tuned for mobile from the first line of code. If you already keep an Obsidian vault, Levity reads it as-is: the same files, the same folders, the same frontmatter. Your notes are just text files. They live in your own iCloud Drive or on your device, sync through your own Apple account, and open in any other editor. A live, clean editor: • Formatting appears as you type. The raw Markdown symbols stay out of your way, while your files stay pure Markdown on disk • Headings, bold, italic, task lists, checkboxes, blockquotes, code blocks, and tables you can edit cell by cell • [[Wiki-links]] between notes, with autocomplete • Inline images • A formatting bar, so you never have to hunt for a raw symbol Organize without a database: • Tag your notes and filter by tag • YAML frontmatter — add any property you like (status, type, dates, lists) and build filtered views around it • Folders, templates, archive, and trash • Full-text search across every note, instantly Made yours: • Seven themes, plus an automatic day / night mode that follows your surroundings • Adjustable font, size, and spacing • Designed for both iPhone and iPad Levity is focused and supports text, tags, and links; no graph view or plugins, just the fastest way to write and read Markdown on iOS, on top of files you already own. Free to start. One optional yearly subscription unlocks unlimited note creation and editing; reading your notes is never limited.
