How Redline works
Redline shows text one word at a time in a fixed spot, with one red letter to fix your eye on. Your eyes stop travelling, so the pace can rise. After every read a quiz checks what you kept, and the pace goes up only when the answers hold.
Take the reading speed test
Read a short passage at your normal pace and answer four questions. You get your words per minute and your comprehension score.
Start at your tested speed
Open a book or paste a link in Redline. Set the pace 50 words a minute above your test result.
Take the quiz after each read
If you score 80% or more, the pace was right. Below that, drop 50 words a minute.
Raise the pace 25 words a minute at a time
Only after two reads in a row at 80% or better. Speed that outruns comprehension does not count.
Train ten minutes a day
Drills widen how much you take in at a glance. Streaks keep you coming back, and the weekly league shows where you stand.
What is in the app
One word at a time
Each word appears in the same spot with one red letter to fix your eye on. Your eyes stop travelling across the line, which is where reading time goes.
A quiz after every read
Speed is easy to fake. After each read you answer questions on what you just read, so your words-per-minute is a number you earned.
Retention checks
The questions come back later. What you kept after a week is the real score.
Read anything
Books, PDFs, Word files, web articles, podcasts and videos. Audio is transcribed so you can read it faster than anyone can say it.
Training that feels like a game
Sixty levels, daily streaks, weekly leagues and clans. Drills for eye span, focus and vocabulary.
New words, kept
Tap any word for its meaning. Words you look up go to My Words and come back as flashcards.
