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.

What's new in 3.0:
A new look for Strobe, plus a big update shaped by reader feedback: new display options, smarter timing, and cleaner text.
A NEW LOOK
• Your library shows every document as a cover, with New, your progress, or Finished underneath.
• Continue Reading, at the top of the library, takes you straight back to your word and shows how much time is left.
• Books with chapters open to a new book page where you can resume, check your progress, and see how long each chapter takes.
• Settings is simpler, with a live preview of the word as you change its font, size, and color. Timing options have their own page.
• Adding text is quicker, with a Paste button and a word count that shows how long it'll take to read.
• Importing no longer covers the screen: the new document shows up in your library, with a Cancel button, while it's added.
• The reading screen works just like before.
ON MAC
• A real toolbar with search, sort, and add, and no more doubled-up buttons.
• New Text (⌘N) and Import File (⌘O) in the File menu.
• Settings is now organized into tabs.
NEW DISPLAY OPTIONS
• True Black Background (Settings › Reading): pure black behind the words, great for OLED screens and reading in the dark.
In Settings › While Reading (Settings › Display on Mac):
• Document Title and Current Chapter: show the document's title and current chapter faintly at the top.
• Previous and Next Words: see the words before and after the current one, dimmed, on either side of it.
• Open Quotes and Parentheses: keeps an opening quote or parenthesis faintly above the word until it closes, so you always know you're inside one.
SMARTER TIMING
• Sentence Pauses is now Punctuation Pauses, in Settings › Timing. It also pauses at commas, colons, semicolons, dashes, ellipses, and closing brackets and quotes, and you can set each one's length.
• Blank After Sentences: an optional moment of empty screen between sentences, with a length you can adjust. It doesn't trigger after abbreviations like Mr. or U.S.
• Acronyms like FBI, NASA, and COVID-19 stay on screen a little longer, since they're read letter by letter.
• Hyphenated words like well-known and long-term get a little extra time for each part.
CLEANER TEXT
• Chapter titles no longer play twice: after a chapter is announced, reading picks up right after its heading. This works for documents already in your library.
• Words joined by a long dash, like "elements—stone", now appear one at a time.
• Years and times like 2000 BCE, 44 B.C., and 10:30 PM stay together as one word.
• Phrases like "pre- and post-war" now read correctly.
The last three apply to documents you import after updating.
IMPROVEMENTS AND FIXES
• The word now appears in the same spot on screen in every document.
• The highlighted focus letter lands in a better place on numbers, years, and times.
