Koodo Reader, by App by Troye, is an open-source ebook manager for organizing and presenting digital reading material. The app offers cross-device library access, customizable display options for long sessions, and tools to manage large collections across mobile and desktop environments with import and tagging support. Notable for format flexibility, cross-platform availability, configurable reader settings, and developer emphasis on privacy and open licensing. Aimed at avid readers, students, and researchers who need organized access to digital libraries with privacy controls.

What formats can the app read?

The app supports more than fifteen document and comic formats, which helps learners keep varied materials together during study. Supported formats include:

• EPUB, PDF, MOBI, AZW3
• FB2, TXT, Markdown, DOCX
• CBR, CBZ, CBT, CB7

How does the app support study and research workflows?

The app includes built-in reading aids and library tools aimed at research use. It provides instant translation, smart summarization, and dictionary lookups to clarify passages quickly. Annotation features let readers highlight, underline, and take exportable notes for citation or review. Advanced search, bookshelves, and tag-based organization help assemble subject-specific collections and prepare focused reading lists for coursework or literature surveys.

Is the app suitable for different learners and device setups?

The app runs on Android (requires Android 5.0 or later) and is available across iOS, Windows, macOS, Linux, and as a web application, making it adaptable for classroom and independent study setups. A 'Pro' option adds enhanced AI tools and simplified synchronization workflows for users who prefer fewer configuration steps. The project is developed by the creator operating as the developer and is licensed under the GNU Affero General Public License v3.0.

How does synchronization and self-hosting work in practice?

The app connects to mainstream cloud providers and self-hosted protocols for library syncing, including Google Drive, Dropbox, OneDrive, WebDAV, and SFTP; self-hosting via Docker is also supported. It synchronizes library state, reading progress, notes, and highlights across devices so study sessions pick up where they left off. The privacy design avoids embedded tracking and does not proactively upload reading data to private servers.

Practical choice for organized learners willing to invest setup time

The app is a practical option for students and researchers who manage substantial digital libraries and prefer an open-source, privacy-minded tool. Expect a reliable study companion once cloud or self-hosted synchronization is configured, since initial setup can demand technical attention. Those seeking immediate, zero-configuration sync should weigh the onboarding step against the long-term benefit of controlled library management and cross-device continuity.
