ZeroPage is a read-only viewer for quickly and beautifully reading Markdown, HTML, text, and PDF documents stored in iCloud Drive on iPhone and iPad. Write anywhere, read comfortably. ZeroPage focuses on one thing: reading. Your ZeroPage folder in iCloud Drive becomes your document library. Browse folders, find documents by filename or body text, and reopen recent documents from History. It shares the same library with ZeroPage for Mac, so you can continue on iPhone or iPad while you’re out. You can also open .md, .markdown, .html, .htm, .txt, and .pdf files from the Files app or other apps. Get to what you need • Jump through long documents with the heading outline • Find words and passages with in-document search • Library search looks in filenames and body text—reach the right file from a half-remembered line • On iPhone, focus on the body; on iPad, show the library, outline, and body side by side Markdown, HTML, text, and PDF • Place PDFs in the same folder and read them there. Move around with the embedded table of contents and body search • Display Markdown with tables, task lists, code blocks, Mermaid diagrams, local images, and links in a readable layout • Code blocks are syntax-highlighted by language and can be copied with one tap • Plain .txt is shown with line breaks and spacing preserved—not interpreted as Markdown • Local HTML also supports outline and in-document search • Share the original file • Adjust text size, line spacing, and appearance • Supports VoiceOver and Dynamic Type Built for reading READMEs, specs, meeting notes, research notes, documents written by AI. We read every day, yet apps made for reading are surprisingly rare. With ZeroPage, you can focus on the content without worrying about editing the original by mistake. External images, styles, fonts, and JavaScript in HTML are limited by default. ZeroPage is not a general-purpose web browser—it’s a viewer for reading documents you already have, safely. For documents you trust, you can allow only what you need for the current reading session. ZeroPage Premium The app shows ads. Premium is a monthly auto-renewing subscription. While subscribed, all ads on iPhone and iPad are hidden, and you can export Markdown, HTML, and text documents as PDF. After export, you can choose in Settings whether to open the share sheet or save to Files. Restore purchases and manage your subscription in the app. Document loading, search, display, and PDF generation run on your iPhone or iPad. Network communication occurs only if you allow loading external resources such as images in HTML. Terms of Use: https://516k.net/terms/ Privacy Policy: https://516k.net/privacy/

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.

Verdict

The call

The clearest difference is ads: HTML Reader Offline at none against ZeroPage's shown. HTML Reader Offline also leads on iOS requirement (16 vs 26.0). ZeroPage's advantage is update cadence (every 2 days vs every 6 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.
