First launch

The build is ad-hoc signed, not notarised with an Apple Developer ID, so macOS will block the first launch. Unzip it into Applications, double-click, dismiss the warning, then go to System Settings → Privacy & Security and click Open Anyway.

Or clear the quarantine flag from the Terminal:

xattr -dr com.apple.quarantine /Applications/Flipbook.app

What's in it

• Gesture-tracked 3D page turn — interruptible and reversible mid-turn
• Book, continuous scroll and reflow reading modes
• Nine reading themes with a lightness-preserving smart invert for dark
• Freehand highlighter, sticky notes, ribbon bookmarks
• Library with self-computing shelves; dashboard with streaks and goals
• Ask about the page you're reading, and author personas grounded in your own books — bring your own API key (Anthropic, OpenAI, Gemini, YUNWU)

No backend, no account, no telemetry. API keys live in the macOS Keychain.
