About Speed Leaf

Speed Leaf uses Rapid Serial Visual Presentation (RSVP) to display text one word at a time at adjustable speeds. By keeping your eyes fixed on a single point, you eliminate the saccadic eye movements that slow down traditional reading - helping you read faster with less effort.

Import your PDF and EPUB documents, adjust your reading speed from 100 to 800 words per minute, and track your progress over time.
