Strobe - Rapid Serial Reader

Read faster. Stay focused. Keep your documents private.

Strobe is a fast, focused speed reader for iPhone, iPad, and Mac. Using Rapid Serial Visual Presentation (RSVP), Strobe presents text one word at a time so you can move through dense material without constantly scanning across the page.

Import a PDF, EPUB, plain-text, or Markdown file, or paste text directly. Choose your pace from 100 to 1000 words per minute and start reading.
