Ledor

Ledor is an open-source reader for EPUBs, web articles, and RSVP speed reading. It best suits readers who want several ways to read and tune their display without paying. Its breadth is appealing, though keeping a library in sync across devices requires optional Google Drive.

Overview

Ledor combines rapid word-by-word reading with a conventional e-reader and text-to-speech narration. That makes it a better fit for readers who move between articles, books, and listening than for someone seeking only a basic ebook shelf. EPUB import and saving articles by URL cover common reading material, while Android users can also share a page directly to the app.

Key features

Reading modes and controls

RSVP is the speed-reading mode; conventional e-reader view offers a more familiar way through a book, and text-to-speech provides an audio option. TTS uses system voices, has lock-screen controls, and supports speeds from 0.5× to 3×. The speed range and playback controls are useful, but the voice selection and quality depend on the system voices available on the device.

Readers can adjust colors, fonts, text sizes, and positions, preview changes live, and choose light or dark themes. These controls give readers room to tailor the display rather than accept a fixed layout.

Offline reading, sync, and privacy

Ledor says it works without internet and stores books and progress on the device. Optional Google Drive sync can carry the library, progress, bookmarks, ratings, sessions, and display settings across devices. Ledor says it uses Drive's drive.file scope to access only files it created, with data traveling directly between the device and Google Drive. Sync is a practical option for readers switching devices, but it is not automatic account-based syncing through Ledor itself.

The privacy policy says Ledor collects no data and has no analytics, ads, tracking, accounts, or servers of its own. Weekly and monthly reading charts and a shareable monthly recap are calculated on the device. The MIT license and GitHub issues, pull requests, and forks offer a route for users who want to inspect or contribute to the project.

Pricing

Ledor's Free plan costs nothing and includes all features, with no ads and no account. There is no free trial because the app is free. Readers do not have to give up customization, reading modes, or sync access for a paid tier; Google Drive sync remains optional.

Platforms

Ledor supports Android, iOS, Linux, and web. Android also supports sharing a page directly to the app. Optional Google Drive sync is the stated way to carry reading data across devices.

Who it's for

Ledor is a strong fit for readers who want EPUB and web-article support alongside RSVP, narration, customizable display controls, and offline access without a subscription or account. It is less compelling for someone who only wants a conventional reader, or who expects cross-device syncing without connecting Google Drive.

Pros and cons

• Pros: All features are free, with no ads or account requirement, so the reading modes and display controls are not reserved for paid users.
• Pros: On-device books, progress, and statistics support offline reading without Ledor accounts or servers.
• Pros: Optional Drive sync covers a broad set of reading data, not just the library.
• Cons: Cross-device sync depends on Google Drive, which may not suit readers who want a service independent of that platform.
• Cons: TTS relies on system voices, so voice quality depends on the device.

Verdict

Choose Ledor if you want a free, open-source reader that combines RSVP, EPUB and article reading, narration, and flexible display controls with offline use. Its main advantage is that the full feature set is free without an account; look elsewhere if you need cross-device sync that does not rely on Google Drive or want narration voices beyond those your device provides.
