Bamboo Lite vs OneOpen

Bamboo (简帛) is a beautifully restrained, fully offline reader built for one thing: making long-form writing readable again. That tutorial you bookmarked. The newsletter you've been meaning to finish. The lecture notes shared in a group chat. The README that scrolls forever. Open them in the Files app and they show up as broken plain text or mangled code blocks. Bamboo turns them into ink on rice paper — measured line height, restrained type, IDE-grade code highlighting, generous white space. WHO IT'S FOR • Read-later collectors who actually want to read it later • Bloggers and newsletter writers • Students and researchers reading lecture notes & papers • Developers reading READMEs and technical blogs • Anyone who wants to finish a good article without distraction REFINED TYPOGRAPHY • Full GFM: headings, tables, task lists, footnotes, blockquotes • Prism.js highlighting for 20+ languages, one-tap copy • Built-in humanist fonts (LXGW WenKai), live font-size control OPEN FROM ANYWHERE • .md / .html from WeChat, Telegram, Mail, Files — tap "Open with..." → done • Or open files directly from the Files app • Share Extension brings Bamboo into every share sheet ONE PIECE, MANY USES • Export as a long image — share to social with watermark • Export as PDF with auto-generated outline • Three curated themes: White Silk, Dark Bamboo, Cyan Reed ON YOUR DESK • Read documents auto-land on the "Bookshelf" • Star to keep favorites within reach • "Timeline" walks back through your reading journey PURE PRIVACY • No accounts. No cache. No cloud servers. • 100% local parsing & rendering, fully offline • No analytics SDK, no ads, no tracking For the written word — Bamboo.

OneOpen is a multi-format file viewer for iPhone and iPad. Open documents, web pages, CAD drawings, 3D models and archives from Files, Mail and apps that support document sharing. HTML and Markdown Preview HTML, HTM and XHTML pages. Read Markdown / MD notes with headings, a table of contents, tables, code fences, task lists, footnotes and reference links. ZIP websites retain local images, styles and relative resources. Markdown in packages can display supported local images. Ordinary HTML allows restricted HTTPS/WSS networking by default, with offline and Safe Preview options. Markdown does not run scripts or load remote images. CAD drawings and 3D models (Advanced) • Pan, zoom and toggle layers in supported DWG/DXF 2D model-space drawings. • Rotate STEP/STP, IGES/IGS, BREP/BRP, STL, OBJ and PLY models, including PLY vertex colors and point clouds. • ZIP a complete OBJ model folder to load supported MTL materials, PNG/JPEG textures, normals, transparency and groups. A standalone OBJ shows geometry without reading private neighboring files. • Preview supported static GLB / glTF 2.0 geometry, nodes, basic materials and PNG/JPEG textures. Model ZIPs retain relative resources. JSON and model information have separate views. • USDZ starts in object view; choose AR when needed. • Included models and engineering drawings demonstrate supported features. Everyday viewing is free Read PDF, Office/iWork, images, audio/video, JSON, XML, YAML, CSV, code and text. PDF supports continuous reading, zoom, search and page controls that hide while scrolling. Edit supported text in an independent working copy. Archives and EPUB Browse ZIP, 7Z, RAR, TAR, GZ, BZ2, XZ and supported TAR combinations. Open or share supported entries and save extracted files to Files. ZIP and EPUB remain free; other archive formats require Advanced Access. EPUB follows the declared chapter order, with a table of contents, previous/next controls, current-chapter search and reading settings. Pages stay offline. A chapter error keeps navigation available. DRM, media overlays, annotations and whole-book search are unsupported. Email, certificates and information Decode EML headers, body text, common character encodings and attachment filenames. Open or share readable attachments independently. HTML email becomes text without loading remote content. Decryption, signature verification and TNEF extraction are not provided. Inspect public CER, DER, CRT and PEM certificate subjects, issuers, validity, algorithms, public keys, usages and SHA-256 fingerprints. Certificates are never installed and device trust is not evaluated. File Information includes PDF metadata, image/camera properties, media tracks, text encoding/line counts and archive summaries. Open from other apps Skippable onboarding uses real iOS screenshots to explain More, Edit and favorite ordering in the share sheet. Revisit it in Settings. Categories, Recents and widgets help you return to files. Advanced Access and compatibility An annual membership or a one-time lifetime purchase unlocks the same specialized features. Check format details before purchasing. DWG supports selected 2D model-space content; DXF supports text files. CAD editing, engineering measurement, native SolidWorks and full external references are unsupported. Compressed glTF geometry, skins and active morphs require conversion. Animation is static; advanced materials may be approximate. ZIP complete model folders, or use self-contained GLB for single-file sharing. Supported AES/ZipCrypto ZIPs prompt for passwords; unsupported encryption/compression, multipart and RAR3 solid are excluded. Native previews depend on iOS codecs/variants. Privacy No account, ads, analytics or document uploads. Non-HTML previews stay offline. HTML and ZIP websites may run JavaScript and connect over HTTPS/WSS in an isolated environment; offline and Safe Preview modes are available.
