Ermine.md MarkDown

Markdown notes saved as real .md files. No account needed, synced with iCloud, and locked notes you open with Face ID.

Ermine is a simple, powerful Markdown notes app to write, organize and keep what matters to you. Every note is a real .md file, so your ideas are never trapped in a proprietary format.

Jot down an idea on the bus, a family recipe, your grocery list, class notes or the docs for your project. No sign up and no account: just open a note and write.
