Markdown Viewer Mobile vs Core 3D Viewer

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.

Core 3D Viewer is a fast, clean 3D model viewer built for people who make and present 3D work: designers, engineers, furniture makers, 3D artists Open your model, set up dimensions and saved views, and show it to your client — on the phone, in AR, or through a web link that works in any browser SUPPORTED FORMATS • GLB, glTF, FBX, OBJ, USDZ, STL, PLY • STEP — full CAD import right on the device, no cloud conversion VIEW • Smooth orbit camera tuned for touch • Blueprint mode: clean engineering look with real contour lines • Original mode: your materials with studio HDRI lighting • Layers: show or hide any part of the model • Tap animations play if your file has them MEASURE & PRESENT (PRO) • Dimensions that snap to geometry and align to main planes • Isolate any part and save it as a view — walk your client through the model view by view • Adjustable label sizes, tick marks and colors, mm or inches SHARE • Share a photo of the current view • Send the model as a USDZ file or export to OBJ, STL, PLY • AR Quick Look: place the model in the real world • Share Link: upload once and send a URL — the recipient sees your model with dimensions and views in the browser, no app or account needed. Update the link when the model changes; delete it anytime. PRIVACY FIRST No accounts. No tracking. Your files stay on your device — a model is uploaded only when you create a share link, and you can revoke it at any time. Core 3D Viewer is free for viewing, AR and one active share link. Dimensions and saved views come with a subscription (7-day free trial on the yearly plan) or a one-time lifetime purchase.
