Open HTML files and ZIP websites on iPhone and iPad — completely offline. No account, no tracking, no ads. HTML Reader Offline turns your device into a portable library for local web content. Save a tutorial, a documentation site, an exported notebook or any .html / .zip bundle, then read it anywhere: on a plane, on the subway, or somewhere with no signal at all. WHY IT'S DIFFERENT • Truly offline. Files live on your device. Nothing is uploaded and no connection is ever required. • Single files or whole sites. Import one .html page, or a ZIP bundle with its CSS, scripts and images intact. • A private space per document. Each document loads in its own isolated storage area, so two tutorials never overwrite each other's saved state or progress. • Fits every screen. The interface adapts to the actual display — compact on a phone, spacious on an iPad or a folding phone's inner screen. READING THAT GETS OUT OF THE WAY • Automatic table of contents built from the page headings — jump to any section in one tap. • Full-text search inside the page, with a match counter and one-tap navigation between hits. • Bookmarks for the passages you want to return to. • Highlights in five colours, each with an optional note; they stay anchored to the text through font changes and rotation. • Adjustable font size, light / dark / sepia themes, and a subtle progress bar. • Reopens exactly where you left off. A LIBRARY YOU CAN ACTUALLY MANAGE • Folders with drag-and-drop, so documents stay organised. • Library-wide search: look across every document at once and land straight on the matching paragraph. • Reading statistics: total time, today's time, your daily streak, and a 7-day chart. • Backup and restore: export the entire library — documents, progress, bookmarks, highlights and settings — into one ZIP file, and bring it back whenever you need it. SHARE WHAT YOU'RE READING • Send a document to anyone as a single .html file, or as a ZIP bundle they can open in any browser or re-import into the app. PRIVACY, PLAINLY No sign-up, no analytics, no advertising, no third-party trackers. The app never makes a network request for you, and your files never leave your device. Tip Jar (optional): Settings → Tip Jar offers a one-time, voluntary tip. It unlocks nothing — every feature in the app is free for everyone. Have a question or an idea? The support link below reaches me directly.

Read full description

Folio keeps HTML files readable, interactive, and available offline—exactly the way they were made. No developer-operated server. No Folio account. No conversion that breaks the layout. Bring in a single HTML file or a folder-based page with its referenced CSS, JavaScript, images, and data. Folio gives each page its own local origin so modern pages—including ES modules, fetch requests, and local storage—can work the way they should. BUILD YOUR LIBRARY • Import files from Files or another app's Share sheet • Import a folder-based page with its referenced supporting files • Watch a folder for new and updated pages • Optionally add and refresh selected files from Google Drive • Organize with favorites, tags, searchable icons, sorting, grouping, and library search • Update many pages at once with bulk actions READ AND USE YOUR PAGES • Stay offline by default, with network access controlled separately for each page • Navigate page history, find text, reload, inspect source, and see useful diagnostics • Choose a top or bottom toolbar that gets out of the way as you read • Download files generated by a page, print, or save and share a PDF • Use a full three-column workspace on iPad or focus on the page full screen • Open chosen pages from widgets, and favorites or recent pages from Home Screen quick actions PRIVATE BY DESIGN • No Folio account, advertising, analytics, or tracking • Optional iCloud sync uses your private iCloud database • Optional Google Drive access is limited to files you choose for Folio • Lock individual pages with Face ID or your device passcode • Locked pages are shielded in the app switcher and badged in widgets and quick actions Two included interactive samples make it easy to explore Folio immediately. Keep reports, dashboards, exported notes, archived documentation, and other web files useful wherever you go—even when the network doesn't.
