Liberotus brings your Grimmory library to iPhone with a calm, immersive reading experience designed around privacy, ownership, and beautiful typography.A native, offline-first reading app for self-hosted libraries.
Download books for offline reading, sync your progress across devices, and carry your personal library with you — without cloud lock-in, tracking, or compromise.
Native iOS Experience
Designed specifically for iPhone using modern SwiftUI and native iOS design principles.
Fast, fluid, and deeply integrated with the platform.
Grimmory Integration
Liberotus connects directly to your Grimmory server.
Browse libraries, shelves, series, and collections as if the server were local.
Offline First
Download books directly to your device for reliable offline reading anywhere.
Your library remains available even when your server is not.
Immersive EPUB Reader
A refined paginated reading experience inspired by the best modern reading apps.
Custom themes, typography controls, bookmarks, and reading progress sync included.
Privacy by Design
Liberotus does not track:
- what you read
- how long you read
- your library contents
- your searches
- or your personal habits.
Your data stays with you and your server.
Local-First Architecture
Liberotus prioritizes local storage and graceful offline behaviour.
Fast startup, resilient syncing, and reliable caching are built into the foundation of the app.
