ZooMark is a Markdown notes app for macOS. As you type, formatting appears instantly, while your text stays clean and portable. Write lightly and clearly in Markdown — no fussy formatting required. ■ Features · Hybrid Markdown editor — bold, italic, headers, lists, to-dos, and code render like formatting as you type, while the source stays plain Markdown text. · Split preview — Editor / Split / Preview modes. In Split, edit on the left and watch the rendered document (with GFM tables and links) on the right at the same time. · Folders — organize notes like Apple Notes; drag to reorder and nest them, and move multiple notes into a folder at once. · Hashtags & internal links — gather notes with #tags, and connect them with [[Title]] wiki links. · Powerful search — find notes fast with tag:, title:, @todo, and "exact phrase" operators. · Themes — light and dark themes (Honey Bear, Solar Cream, Panda, Tasmanian Devil Black, and more), set inside the app independent of the system appearance. · Note lock — hide sensitive notes behind Touch ID or a password. · Import · Export · Share — import .md files; save notes as Markdown, HTML, TXT, or PDF, or share them to other apps. · iCloud sync & backup — when signed in to iCloud, all folders and notes sync and back up across your devices automatically.
