How do the two versions differ?

iPhone is made for quick capture; Mac gives you room to write. Both organize content around Ideas and Knowledge, with a native interface for each platform.

Do I need an account?

No Mark account is required. Open the app to use a local library. Core note-taking and editing features work offline.

Where will updates come from?
