Markdown Viewer Mobile vs ARlimit

MarkdownViewer is a distraction-free reader for .md files on iPhone and iPad. Open a file from Files, AirDrop, or a shared link; or sync an entire documentation repository from GitHub and read it offline. Just exploring? The app ships with a curated library of example documents covering every feature below — sync it with one tap from the "Try it" card on the library screen. RICH RENDERING • Full CommonMark + GitHub Flavored Markdown • Mermaid diagrams rendered inline • LaTeX math (inline and display) via KaTeX-compatible engine • Syntax-highlighted code blocks across 190+ languages • GFM tables, task lists, footnotes, strikethrough • GitHub-style admonitions (NOTE, WARNING, TIP, CAUTION) READING COMFORT • Material 3 design with light, dark, and sepia themes • Adjustable font size, reading width, and line height • Immersive scroll — the app bar fades away as you read • Table of contents drawer with one-tap navigation • In-document search with match counter • Reading-position bookmark — resume exactly where you left off • Keep-screen-on toggle for long-form reading • Reading time estimate BRING YOUR OWN DOCS • Sync any public GitHub repository with a single URL • Private repos supported via a personal access token (stored in the iOS Keychain — never in the app's database) • Incremental re-sync — only changed files download • Re-sync or remove a synced repo from the drawer EXPORT AND SHARE • Export any document to PDF with mermaid diagrams preserved • Share the raw markdown or a rendered PDF via the system share sheet PRIVACY BY DESIGN • No accounts, ever • Zero telemetry by default • Crash reporting is opt-in and excludes document content, file paths, and tokens • The only network traffic is to GitHub when you explicitly sync Made in the open on GitHub.

ARlimit puts your BIM models on the construction site — at full scale, in augmented reality. Print a marker card from the ARlimit web console, place it on site, and scan it with your iPhone. Your IFC model appears exactly where it belongs, aligned with the real structure. Walk the site, compare as-built with as-planned, and produce inspection reports without leaving the field. HOW IT WORKS • Upload IFC models to the web console at arlimit.com • Place anchors on the model and print the matching marker cards • On site, scan a card with the app — the model locks onto the real world • Inspect, annotate, report KEY FEATURES • True-scale AR overlay of BIM/IFC models, anchored to printed markers • Tap a building element to identify it and see its IFC identity • Pin notes in 3D space, exactly where the issue is • Attach annotated photos captured with your phone camera • Generate professional PDF inspection reports from the field • Multi-floor projects and multiple models per project • Team workspaces with roles — owner, member, reporter • AR processing runs fully on-device; live camera frames never leave your phone WHO IT'S FOR BIM engineers, site inspectors, project managers and construction companies that want to close the gap between the model and the built reality. GETTING STARTED An ARlimit workspace account is required. Book a demo at https://arlimit.com and get your organization set up with a free trial. Requires an ARKit-compatible device running iOS 15 or later. Camera access is used only for the AR view and marker scanning. Privacy policy: https://arlimit.com/privacy
