Ledor vs StudyFast Speed Reading Trainer

Ledor is a free, open-source reader for RSVP, EPUB files, and web articles, available on Android, iOS, Linux, and the web. It offers RSVP, text-to-speech narration, and a traditional e-reader mode. Readers can import EPUBs or save articles by URL; Android users can also share a page with the app. Text-to-speech uses system voices, provides lock-screen controls, and supports speeds from 0.5× to 3×. Appearance settings cover colors, fonts, sizes, and positions, with light and dark themes and a live preview.

Ledor works offline, storing books and progress on the device. Optional Google Drive sync can carry the library, progress, bookmarks, ratings, sessions, and display settings across devices. The privacy policy says the app 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-licensed free plan includes all features, with no ads or account required.
