Why this Markdown workflow breaks on iOS

R Markdown files often contain research notes, analysis reports, code chunks, tables, and narrative text. On iPhone, they may appear as raw text instead of a readable preview.

The shortest answer

Install Md Preview, open the file from Files, the Share Sheet, or the source app, and preview it locally. The app has no subscriptions, no in-app purchases, and no ads.

The R Markdown workflow

Save the .rmd file, open it from Files or the iOS Share Sheet, choose Md Preview, and inspect the Markdown structure locally.

What to check before opening

Dynamic R output still belongs to the original project, but headings, prose, tables, links, and code blocks are easier to review in a local Markdown viewer.

Why local preview fits this job

Md Preview is focused on file preview. It avoids uploads, account setup, ad clutter, and heavy editing features when the user simply needs to read a Markdown file now.

If you also receive HTML files

AI and document workflows often produce both Markdown and HTML. Html Preview is the companion viewer for that file type.
