## What is Marble?

Marble is the ebook reader for people who love books, not subscriptions. It’s what Marvin 3 would have become if it were still maintained — beautiful, powerful, and built for power readers.

**Formats that matter. One price. Zero subscriptions.**

Read EPUB, PDF, TXT, DOCX, and CBZ — all in one app. No book limits. No forced cloud. No account required. Just you and your library.

**For OPDS & Calibre Users**
Browse and download from any OPDS 1.2 or 2.0 catalog — Standard Ebooks, Project Gutenberg, Internet Archive, ManyBooks, or your own server. Automatic Bonjour discovery for Calibre Content Servers. Download books directly to your library with one tap.

**Typography That Respects the Page**
Adjust size, font family, line height, margins, and alignment. Switch among carefully crafted themes including Paper, Sepia, Dark, and Pitch. Pro unlocks advanced themes like Leather and Slate.

**Annotations That Travel With You**
Highlight in 10 colors. Add notes. Browse annotations by book. Export to Markdown or CSV with Marble Pro — perfect for Obsidian, Notion, or your own archive.

**Reading Statistics (Pro)**
Track reading time, pages turned, daily streaks, and a year heatmap. All stats stay private on your device unless you choose to sync.

**Comics & CBZ**
Read CBZ comics with pinch zoom and edge-tap page turns. ZIP-based archives open cleanly; true RAR CBR support is coming soon.

**Cloud Storage Import**
Connect Google Drive or Dropbox to browse and import books. Use the Files app for iCloud Drive and local folders.

**iCloud Sync (Pro)**
Keep reading positions and annotations in sync across iPhone and iPad via CloudKit. Book files stay on each device — local-first by design.

**No Account. No Tracking. No Ads.**
Marble is local-first. Your reading data stays on your device unless you choose to sync. No analytics SDKs. No profile building.

**Marble is Free + One-Time Pro**
Use all core local features free, forever. Upgrade to Marble Pro ($4.99 one-time) for iCloud sync, annotation export, reading stats, and advanced themes. No subscription required for Pro.
