LumaRead vs Strobe

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.

Strobe is an RSVP reader for PDFs, EPUBs, and text. It displays one word at a time at a fixed point, with adjustable reading speeds from 100 to 1,000 words per minute. Smart Timing changes word intervals according to word length, punctuation, sentence endings, and complexity. The app imports PDF, EPUB, TXT, and Markdown files and accepts pasted text. Readers can search passages, browse chapters, and resume at the exact word where they stopped. Documents, progress, and settings remain on the device, with no account, analytics, document uploads, or cloud synchronization. Imported text works offline. Accessibility support includes VoiceOver, larger text, Reduced Motion, Dynamic Type, and keyboard controls on compatible devices. Strobe runs on iOS, iPadOS, and macOS. It has a free plan with no subscription, advertisements, or in-app purchases. DRM-protected EPUBs and password-protected PDFs are unsupported, and PDFs need a text layer because the app does not run OCR.
