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.
SpeedyRead
SpeedyRead is an iPhone speed-reading app that presents text one word at a time using Rapid Serial Visual Presentation. It imports PDFs, Word documents, ePubs, Markdown, HTML, and other content, and can open files from the Files app. Readers can also paste a web address for article extraction or scan printed pages with live OCR and torch support. The reading pace can be adjusted from 300 to 725 WPM with a speed wheel and haptic feedback. An audio mode speaks each word in sync with the display, with adjustable audio speed from 50 to 450 WPM and multiple voices.
The app includes comprehension exercises, guided training, dark and light modes, five accent colors, automatic session saving, and reading-position resumption. Its library and progress are stored locally; personal files are not synced to servers unless a future cloud backup is enabled. The privacy policy says anonymous usage statistics are collected, with device model and OS version potentially collected for diagnostics. Support requests may involve an email address. SpeedyRead requires iOS 18.0 or later. It has a free download, and Monthly Premium costs $1.99 a month with a 14-day free trial.
