It focuses on one specific problem: helping you open local HTML, Markdown, and ZIP files more easily on your phone. -- Note -- Because HTML / ZIP files can structure and reference resources in different ways, some images, styles, scripts, or external resources may not display completely. Some Markdown extensions, embedded content, or external resources may also behave differently depending on where the file came from. This app is better suited for quick viewing, temporary previews, and everyday browsing of local HTML / Markdown / ZIP files. --- HTML Keep Pro: HTML Keep Pro is available as annual and monthly subscriptions.
