Dyslexia isn't a reading problem — it's a page problem. When letters swap, merge, or drift across a line of text, the answer isn't 'try harder.' It's to remove the line of text entirely. One word at a time, weighted for legibility, in a font made for you.
Tracking a horizontal line of text is the hardest part of reading for many dyslexic readers. Your eyes have to both read the letters AND hold position on the line. Remove the line and half the work disappears.
Most fonts were designed for print typesetting, not for reading comfort. Letters like b/d, p/q, n/u are near-mirror images. OpenDyslexic was designed to weight each letter uniquely — so your brain can't confuse them.
Not because you're slow. Because the medium is wrong. When the medium fits, you can hit average reading speed easily — sometimes more than average.
Six font choices ship with Readit Fast, and OpenDyslexic is one of them — paired with the rest of the Pro reading toolkit. Weighted letterforms, generous spacing, and the RSVP focal lock mean you spend zero energy fighting the page.
RSVP display removes the horizontal tracking problem entirely. Each word appears centered, one at a time, with the ORP focal letter highlighted in focus orange. Your eyes don't move, so they can't lose the line.
Start at 150 WPM and work up. Many dyslexic readers discover they can comfortably hit 250-350 WPM — average or above — once the page-tracking burden is removed.
Tap to pause. Swipe back. Re-read a word as many times as you want. The reader waits for you, never the other way around.
Pair OpenDyslexic with our high-contrast theme for maximum legibility. Warm sepia is also available for readers who find pure white backgrounds fatiguing.
We didn't bolt on accessibility. The core product IS the accessibility. RSVP, OpenDyslexic, adjustable pace, pause-on-word, high-contrast themes — all free, all defaults, all respectful. You shouldn't have to pay extra to read at the speed your brain is capable of.
Dyslexia isn't a comprehension problem. It's a decoding-and-tracking problem. Remove the tracking demand and the decoding demand drops with it.
For most dyslexic readers, the hardest part of reading isn't the words themselves — it's holding your eye on the correct line while decoding letters. RSVP eliminates that entirely. Every word appears at the same fixed point on screen. Your eyes don't move. There's no line to lose.
Pro unlocks OpenDyslexic along with five other reading fonts. OpenDyslexic weights each letter asymmetrically so b/d/p/q can't visually collapse into each other. Paired with the fixed-point RSVP display, mirror confusion becomes a much smaller problem.
Readit Fast runs from 50 WPM all the way up to 1,500. Many dyslexic readers find their comfortable zone somewhere around 150-300 WPM — which is often still faster than their traditional reading speed, because the tracking tax is gone. Start slow, dial it up only when it feels natural.
Pure white backgrounds are fatiguing for many dyslexic readers. Pro unlocks Sepia (warm off-white), High Contrast (deliberate accessibility theme), and 10 custom color presets. Pair OpenDyslexic with Sepia and most page-strain symptoms drop noticeably.
Tap once to pause on the current word. Use the arrow keys to step backward word by word. Resume when you're ready. The reader waits for you. No one's watching, no one's counting, and the text isn't going anywhere.
Whatever you pick, you're unlocking the full Pro toolkit: semantic chunking, AI comprehension quizzes, adaptive pacing, speed coaching, unlimited queue, and cross-device sync.

OpenDyslexic is part of Pro ($2.99/week and up). The free tier ships with Readit Fast's default serif and sans-serif fonts, which are legible for most readers. If you want OpenDyslexic specifically, it comes bundled with the full Pro toolkit — semantic chunking, AI quizzes, custom themes, unlimited queue — not as a separate purchase.
We can't make clinical claims, but users consistently report that removing the horizontal line-tracking burden makes reading less exhausting. RSVP was originally developed in the 1970s as an assistive reading technology before it became a speed-reading tool.
Yes. Minimum is 50 WPM on the free tier. Some readers start at 100-150 while they get used to the interface, then work up.
Single tap pauses. Arrow keys step forward/backward by word. Pressing space resumes. The control is yours.
RSVP is a visual reading technology, so it doesn't replace screen readers for fully blind readers. For dyslexic readers with functional vision, it's designed to make visual reading less exhausting than a standard page.
