What's New in Outerline

1.2.8

October 14, 2026

What's New in Outerline 1.2.8 • Collapsible sections: fold any heading to tuck away the section beneath it. Place the caret on a heading to show its arrow, then tap to collapse. Collapsed sections are remembered per document on this iPhone, and folding never changes your Markdown, preview, or exports. • Interactive checkboxes: task lists now show real checkboxes in the editor. Tap one to check it off without moving the caret or raising the keyboard; the file stays standard Markdown. On by default, with a switch in Settings → Editor → Completions. • Preview now shows images stored in your library, in both the editor's Preview and Library preview. Images still in iCloud download before they appear. • Write below a collapsed final section: a blank line at the end of the document lets you keep typing without expanding anything. • Smoother scrolling and editing in long, Markdown-heavy notes. • Updated web page import. Fixes for formatting controls lighting up when the caret is in a heading, pasting a URL inside an existing link or image, and one failed image in preview hiding the others in its paragraph.

Exactly what a writing app should be

Really like that my notes stay as regular Markdown files so I can use them wherever I want without feeling tied to one app. Linking notes together feels really natural and the quick search is great once everything starts piling up.

Exactly what a writing app should be

Keeping all my notes as plain Markdown files gives me complete peace of mind. I love that it opens instantly and stays completely out of the way so I can just focus on writing.

This is what a notes app should feel like!

Really like that there’s no clutter and no account, just a clean place to write that still leaves my files as regular Markdown. Opening it is instant and focus mode makes it easy to keep going without distractions.
