A Markdown editor where every note is a plain .md file synced through your own iCloud Drive: syntax that dims or hides as you type, task lists that check, tables and pictures stored beside the note, folders, pins, Spotlight search, Lock Screen widgets and an Apple Watch app. For Mac, iPhone and iPad.
