Strobe vs Lumen Reader

Speed read your own books and documents, one word at a time. No ads, no subscription, no account. Strobe is a speed reading app for iPhone, iPad, and Mac. It uses Rapid Serial Visual Presentation (RSVP): each word appears in the same spot on screen, so your eyes stay still instead of scanning across lines. Import a PDF, EPUB, plain-text, or Markdown file, or paste an article, then read at 100 to 1,000 words per minute. HOLD TO READ • Press and hold to read. Let go to pause. • Slide up or down while you read to change speed without losing your place. • Swipe sideways while paused to step word by word. • Prefer hands-free? Switch to tap to play. TIMING THAT FOLLOWS THE TEXT • Smart Timing keeps longer words on screen a little longer. • Punctuation Pauses slow down at sentence ends, commas, dashes, ellipses, and closing quotes, and you set the length of each. • Complexity Timing speeds up common words and slows down rare ones. • Acronyms and hyphenated words get extra time automatically. • Blank After Sentences adds an optional moment of empty screen between sentences. A FIXED POINT FOR YOUR EYES • Each word lines up on a red focus letter, its Optimal Recognition Point (ORP). • Show the previous and next words faintly on either side. • An open quote or parenthesis stays faintly above the word until it closes. YOUR LIBRARY • Every document gets a cover, and Continue Reading takes you back to your exact word. • EPUB tables of contents and PDF bookmarks become chapters, each with its reading time at your speed. • Open the full text with your place highlighted, search for any word or phrase, and tap a word to resume from there. • Page numbers, running headers, and footers are removed on import. • Chinese, Japanese, and Korean text is split into words, and Arabic keeps its connected letterforms. MAKE IT YOURS • Seven fonts, adjustable text size, and four text colors. • A true black background for OLED screens and reading in the dark. • Every document remembers its own speed. • Keyboard shortcuts on Mac and iPad: Space to read, arrow keys to step, ⌘N for new text, ⌘O to import. • Works with VoiceOver, Larger Text, and Reduced Motion. PRIVATE BY DESIGN Your documents and reading progress stay on your device. Strobe needs no account and has no ads, analytics, or tracking. FREE AND OPEN SOURCE Strobe is free, with no subscription or in-app purchases. The source code is public on GitHub under the Apache 2.0 license. Strobe can't import DRM-protected EPUBs or password-protected PDFs.

Lumen Reader turns any webpage, EPUB, PDF, or DOCX into a clean audiobook with on-device narration, lock-screen controls, and word-by-word highlights. Paste a link, tap Listen — no ads, no account, no subscription. PASTE A LINK. GET AN AUDIOBOOK. Found a 10,000-word essay you'd never sit down to read? An hour-long blog post? A web-novel chapter buried under five ad slots? Paste the URL into Lumen. The page is stripped of pop-ups, trackers, cookie walls, newsletter dialogs, and "related articles" carousels — then handed to a natural narrator that starts reading aloud while you keep walking, cooking, or driving. POCKET AUDIO PLAYER Lumen feels like a podcast app, not a reading app, when you want it to. The big Listen button is on every book and every imported article. Lock-screen controls let you play, pause, scrub, skip back 15 s, or jump chapter without unlocking your phone. AirPods double-tap, CarPlay, Dynamic Island, and Bluetooth headphones all work out of the box. Background audio keeps the narrator going when the screen is off. OR READ INSTEAD The same content is also a beautifully typeset, minimalist reader. Three themes (Dark, Sepia, Light) and four type families (Georgia serif, sans, rounded, OpenDyslexic) tuned for multi-hour sessions. Sentence-granular highlights in five colours, per-chapter bookmarks, and a notes catalog searchable across every book. A soft amber word-highlight scrolls along the page in time with the audio when you read and listen at the same time. BUILT-IN LIBRARY Open the app and there's already something to read or listen to. A curated catalog of public-domain titles is one tap away: • The Holy Bible (King James Version) • The Holy Qur-ān (public-domain English translation) • The Bhagavad Gita • The Dhammapada · Tao Te Ching · Analects of Confucius • Meditations (Marcus Aurelius) · The Art of War · Walden • Pride and Prejudice · Frankenstein · Dracula · Moby-Dick • Sherlock Holmes · Alice in Wonderland · The Iliad & The Odyssey • …plus developer docs (Snowflake, Databricks) rendered on-device. Books download straight from canonical archives like Project Gutenberg in seconds — no account, yours forever. YOUR OWN FILES TOO Drop EPUB, PDF, DOCX, TXT, Markdown, or HTML in from Files, iCloud Drive, Dropbox, Google Drive, or OneDrive. Lumen parses chapters into the same clean reader and audiobook UI. ONE LIBRARY ON EVERY DEVICE iCloud syncs your reading progress, highlights, notes, and imported books across iPhone, iPad, Mac, and Apple Vision Pro — silently, with no login. Start a chapter on your phone, finish it on your iPad with the audio resuming at the exact word. OFFLINE BY DEFAULT Every page and audio session is generated on-device. Once a book is downloaded, you never need a signal to re-open it. PRIVACY No account. No analytics. No tracking. Highlights, notes, and progress stay in your own iCloud — never on our servers. The app talks only to the page you explicitly paste, or runs entirely offline against the bundled library. FINE PRINT Every catalog title is public domain or permissively licensed. Lumen does not bundle copyrighted prose and does not redistribute from its own servers — downloads go straight from the canonical archive to your device. For pages or files you import, you're responsible for the rights. Read it. Hear it. Pocket it.
