Stasis: The Quiet Way to Read Fast. One word. One point of stillness. Stasis is a reading sanctuary — a minimalist RSVP speed reader that streams your books through a single focal point. Your eyes stay still. Your mind moves fast. The Science of Stillness Traditional reading is quietly exhausting. Your eyes leap from word to word, stumble, circle back — most of your energy spent on the journey, not the meaning. Stasis removes the journey. Each word arrives exactly where your eyes already rest, and your brain processes language at its natural, unhurried speed. Focus, Refined — The RSVP engine: fluid delivery from 50 to 1,000 WPM — Paced comprehension: micro-pauses that breathe with the punctuation, so speed never costs understanding — An interface that vanishes: no scrolling, no page-turns, no noise — Ambient sound: rain, fireplace, birdsong — a room tone for your reading — OLED-deep themes and serif typography, tuned for long sessions For Every Kind of Reader Restless attention, wandering focus, or dyslexia — the portal meets you where you are. Choose from curated reading fonts including OpenDyslexic, Atkinson Hyperlegible, and Lexend. Your Library, Accelerated Import EPUBs and PDFs or paste any text. Chapters, table of contents, and progress are preserved — your "to-read" pile quietly becomes a "finished" list. A Habit, Not a Chore Streaks that forgive. Monthly reading reports that celebrate what you did — never guilt for what you didn't. Watch your pace grow, then share your month as a single beautiful card. Everywhere You Read A free account backs up your library and syncs your progress across devices. Close the app on the train, reopen it on the couch — the next word is waiting. Read faster. Stay longer. That's Stasis.

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.
