Open Riffle on your phone, tap scan, and shoot as many pages as you need. Photos are shrunk on your phone before they upload, so a chapter takes seconds, not minutes. PDFs, Word files and pasted text work too.
How the eye reads
Your eyes do not glide across a line of text. They jump. Each jump, called a saccade, lands on a word for about a quarter of a second, and in that pause the brain does its work.
Most of the time you spend reading is spent moving, not seeing.
Removing the moving
A speed reader holds each word at the same spot on the screen and lets the words come to you, one after another.

The scan goes to a reading model that returns the words in order, with headings and paragraphs kept where they were. It names the text for you. Rename it whenever you like.

Riffle through it
Read one word at a time with the focus letter held still, or read the full text with the current sentence lit. Set your pace, your type size, your colors. They follow you to every device.
Scroll to read.
Each nudge of the scrollbar is one word. In the app the words come on their own, at a pace you set.
Keep scrolling
Two ways to read.
Word by word holds each word still with the focus letter marked, so you stop moving your eyes. Full text keeps the whole page in view and lights the sentence you are on, word by word or sentence by sentence.
Switch between them any time. Your place is kept.
Your eyes do not glide across a line of text. They jump. Each jump, called a saccade, lands on a word for about a quarter of a second, and in that pause the brain does its work. Most of the time you spend reading is spent moving, not seeing.
A speed reader removes the moving. It holds each word at the same spot on the screen and lets the words come to you, one after another, so the only thing left to do is understand.
Riffle marks one letter in every word, slightly left of center. That letter is where the eye recognizes a word fastest. Keep your gaze on it and the rest of the word fills in on its own.
Start slow. Four hundred words a minute feels fast for a day and ordinary for a week.
