KNFB Reader gives you instant access to print anytime and anywhere. KNFB Reader 3.0 is a rapid and efficient text recognition app. Its text-to-speech, text-to-Braille, and text highlighting tools make it valuable for blind, low-vision, dyslexic, and others with reading differences. Use it to import or take a photo of anything containing text. Take a photo and the app reads text out loud or displays it on a connected refreshable Braille display. Read with more ease thanks to the simultaneous highlighting of the sentence and word that is being read on the picture or in the plain text document. The app helps you get a good photo with special alignment tools, including spoken and vibration guidance. Snap multiple pages, such as a book, for later reading. Winner of the 2014, 2015, and 2016 AppleVis Golden Apple Award for Best Assistive Technology App. • Reads image-based PDF and JPEG files, and now tagged PDF and ePub files too! • Exports KNFB reader files as HTML or TXT files. • Navigates by line, sentence, word, or character. • Crop, rotate and edit the pictures you take before performing text recognition. • View documents in PDF presentation mode with double highlighting while reading. • View reading order and language-tagged PDF documents. • Add and remove bookmarks in PDF documents. • Switch between PDF view and reflowable text view. • Read documents in the increasingly popular ePub format. The app also has synchronized text highlighting to help you read along with the spoken text, a benefit for people with dyslexia and other reading difficulties.

  • Do not use this app

    By They'd his
    I can no longer take pictures using this app. Every time I try to do so I get an error message that says an error occurred while taking a picture and the operation could not be completed

  • My Reader

    By chenry2131
    I am so excited that I’m able to finally mail books etc. I’m still learning to navigate around it , but it’s getting better with practice
  • I love this app!

    By successwiz
    This app is AMAZING! Absolutely worth every penny! Use it every day super user-friendly. does as good a job as larger, less portable and much more expensive external devices. HIGHLY recommend.
  • A podcast or tutorial

    By tacoburn70
    I Purchased this app when it was half-price because I figured it doesn’t go at half price very often. that was like, a year or two ago, and I’ve still yet to understand how to use this app? back then I used zoom and magnification mostly, now I use voiceover, so using this app is going to be even more challenging for me now that I’m using voice over. I wish there was a podcast on demonstrating or how to use this app. I think people would agree to pay the high cost if they could see or hear a demonstration of its use. That would even help me since I have purchased the app and still don’t know how to use it. that would drive up your sales, and help me at the same time. for example, instructions on how to use it, what you can use it to do, etc.
  • Want my money back!

    By plagaise
    This app is ridiculously overpriced for what it offers. Not only that, but every time I try to scan a large document the app crashes. I could have bot an OCR app for less than 10 dollars that does the exact same thing this app does. Stay away from this app!
  • Broken on my iPhone max

    By Zip54
    In the past I have greatly appreciated the benefits of this application. Since upgrading to my new iPhone max the application simply will not load and therefore is entirely useless to me. I hope that in adjustment will be coming soon but I’ve been waiting for too long already.
  • Was great until version 3.0

    By VoiceOver user.
    I’d had this app for more than three years, and have really liked it overall, even though I am a bit of a klutz. However, with Version 3.0, it has become much more difficult to use, at least for this user. For one thing, the new user manual isn’t very helpful; it tells us what the app can do, but doesn’t really tell us _how to do things. With this significant an update, giving us the how-to is extremely important. For instance, importing text from other sources used to be very straightforward—and it worked well. Now, when I try to import something, I first have to find where the material _went. At first, in this version, it went into a folder called “Inbox” (not even mentioned in the user manual). With the latest update, however, “Inbox” is gone, and I have to search for it among the saved files, even though it technically hasn’t been saved yet. Then, I have to go through all kinds of hoops to save the document in a form that will recognize the text. Sometimes, the field of view report doesn’t work now. The whole thing is just harder to use, especially if I am saving documents. If the user manual were written from the viewpoint of a _new user, it would benefit all of us. Prior to this, I would have given it a higher rating. Update, Jan. 10, 2019: It just keeps getting worse. It still does reasonably well for reading and saving otherwise inaccessible material from websites; but, with iOS 12 and later, scanning documents such as books, magazines, and even mail is becoming less successful. Even reinstalling the app didn’t help. More often than not, the reading comes out Like gibberish now; the automatic picture function almost _never works, and the field of view report is frequently unavailable; at times, it says that the page is upside down when it isn’t; and, in fact, just about the only people who _might be able to benefit from scanning documents with it are sighted users who have different reading difficulties, such as dyslexia. Really, there should be one app for sightless users, and a different one for sighted users. That way, more focus could be given to having all features working and updated. I’m only keeping the three stars because of the ability to import text from otherwise inaccessible websites.
  • Gotten much better

    By Low vision Star
    This app has gotten much better and much more useful than it has been in the past and I like that. I look forward to seeing how much better this app will become. The truth is it’s not at its hundred dollar price tag yet but there have been great improvements and I would like to see more tools being rolled out in the app.
