The full review of Ledor
Overview
Ledor is a free, open-source reading app for people who want speed reading alongside conventional ebooks and narrated text. It suits readers who value flexible controls and local reading without an account; the trade-off is that cross-device syncing depends on optional Google Drive.
Key features
Ledor brings together RSVP, a traditional e-reader and text-to-speech, so readers can switch between rapid word presentation, page-based reading and listening. You can import EPUB files or save web articles by URL; Android users can also share a page directly to the app. That range makes Ledor useful for mixed reading habits, though RSVP and narration will matter less to someone seeking only a basic ebook reader.
Customization covers colors, fonts, text sizes and positions, with light and dark themes and a live preview. These options let readers tune the display without a paid tier. Text-to-speech uses system voices, includes lock-screen controls and supports speeds from 0.5× to 3×. The controls are versatile, but the voice quality depends on the voices available on the device.
Ledor stores books and progress on the device and says it works without internet. Optional Google Drive sync can carry the library, reading progress, bookmarks, ratings, sessions and display settings across devices. Ledor says it uses Drive's drive.file scope to access only files it created, and data travels directly between the device and Google Drive. Sync adds continuity for people using multiple devices, while local storage and offline use suit readers who prefer not to rely on it.
Weekly and monthly reading charts and a shareable monthly recap offer a view of reading habits; calculations happen on the device. Ledor's privacy policy says the app has no analytics, ads, tracking, accounts of its own or servers of its own, and that it collects no data. Its MIT license and GitHub issues, pull requests and forks give technically minded users ways to contribute or ask questions.
Pricing
Ledor's Free plan costs nothing and includes all features, with no ads and no account. There is no free trial because the full app is already free. That makes it an unusually straightforward fit for readers who want customization, multiple reading modes and optional sync without a subscription; there is no paid tier to unlock additional capabilities.
Platforms
Ledor supports Android, iOS, Linux and web. Android has the additional option to share a page directly with the app. The combination spans mobile, desktop Linux and browser use, while the listed platform range does not include Windows or macOS.
Who it's for
Choose Ledor if you want a no-cost, open-source reader that handles EPUBs and web articles as well as RSVP, with narration, extensive appearance controls and offline use. It is particularly well suited to readers who want their books and progress stored locally, or who want optional Google Drive sync without an account of Ledor's own. If conventional ebook reading alone is the priority, its extra modes may be more than you need.
Pros and cons
- Pro: RSVP, TTS and traditional reading are combined, making one app adaptable to different reading situations.
- Pro: EPUB and URL import, plus Android sharing, provide several ways to bring reading material in.
- Pro: All features are free, with no ads or account, and reading works offline.
- Pro: Optional Drive sync includes progress and display settings, not just the library.
- Con: TTS relies on system voices, so the listening experience depends on the device's installed voices.
- Con: Cross-device continuity requires optional Google Drive sync; readers wanting a built-in service from Ledor will need another approach.

Verdict
