In their own words
Ledor
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.
LumaRead
LumaRead is a web-based speed reading app that presents text one word at a time using rapid serial visual presentation (RSVP). It accepts PDF and DOCX uploads and includes a free reading speed test that measures words per minute. The reader removes headers, footers and page numbers, anchoring words at an optical center point; readers can adjust speed, with pacing that responds to punctuation. The free plan saves progress and allows 1,500 words per day, one book in the library and speeds up to 600 WPM. Monthly costs $3.99 a month and allows unlimited reading, 10 library books and speeds up to 900 WPM, with reading statistics. Yearly costs $39.99 a year and adds an unlimited library, custom speeds up to 1,500 WPM, statistics, streaks and priority support. Login, library sync and session statistics require an internet connection. A loaded book can continue in an active session if it remains open on the page. LumaRead can be installed as a PWA for quicker access on mobile or desktop, though the supported platform is web.
