Tertiary Markdown vs ARlimit

Tertiary Markdown is a fast, native Markdown notes app for Mac, iPad, and iPhone. It manages your files and folders the way Obsidian does — open any local folder as a vault and your notes stay as plain .md files you fully own. KEY FEATURES • Open any folder as a vault — fully compatible with your existing Obsidian vault. Your notes are plain Markdown files, never locked into a proprietary format. • File & folder management — browse, create, rename, and delete notes and folders from a clean sidebar. • Live preview editor — switch instantly between Edit, Split, and Preview. Your work autosaves as you type. • Images, Bear-style — embed pictures with standard Markdown  or Obsidian ![[image.png]] embeds, rendered inline. • Tables, Notion-style — GitHub-flavoured tables render as clean, bordered grids. • Everyday Markdown — headings, bold and italic, links, checklists, bullet and numbered lists, block quotes, and code blocks. • One app, every device — a true native experience on macOS, iPadOS, and iOS. Your notes never leave your device. Everything is stored as simple text files on your Mac, iPad, or iPhone, so you stay in control and your library is future-proof. Whether you keep a personal knowledge base, take meeting notes, or write long-form drafts, Tertiary Markdown gives you a distraction-free, Markdown-first workspace that travels with you.
