LibreEdit

LibreEdit intended to be a simple open-source text editing app for iOS, written in Swift.

LibreEdit integrates with the native iOS file manager, allowing users full control over the files themselves. The editor is simple and should display all file types.

There is an option to view rendered Markdown in the secondary actions menu in the naviation bar.
