## What is Folio?

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.


## Version history (last 4 releases)

### 1.1.2 — 2026-08-30

Fixes a Google Drive refresh issue that could leave an already-open file showing an older version after the Drive file changed. Folio now verifies downloaded file contents, repairs stale saved copies in place, and preserves the last working copy if an update is interrupted.

### 1.1.1 — 2026-08-29

Fixes a bug on iOS 26 where the ＋ menu's import options — Import a File, Import a Folder as One Page, and Watch a Folder for Pages — closed the menu without opening a picker.

### 1.1 — 2026-08-28

Folio 1.1 is our biggest update yet—a new library, a more capable reader, and private ways to organize and sync your pages.

• Optionally sync your library through your private iCloud database, with separate choices for page files and app settings.
• Add and refresh selected files from Google Drive without creating a Folio account.
• Work in a true three-column iPad layout, or focus on a page full screen.
• Organize pages with tags, favorites, custom icons, sorting, grouping, search, and bulk actions.
• Import a folder-based page with its referenced CSS, JavaScript, images, and data.
• Run richer offline pages with ES modules, fetch, root-relative assets, isolated storage, and helpful diagnostics.
• Lock individual pages with Face ID or your device passcode, with privacy protection in the app switcher.
• Open chosen pages from widgets, and favorites or recent pages from Home Screen quick actions.
• Use a redesigned, configurable reader toolbar with history, find, reload progress, printing, downloads, and improved PDF sharing.
• Start with two built-in interactive samples that show exactly what Folio can do.

This release also includes extensive import, folder-sync, layout, and data-safety improvements.
