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.

  • Ever since Ios12

    By vicious mole
    I miss the easy way you use to be able to access imported files from another app, it use to be that explorer was at the top of the screen and tapping on this instantly opened your imported file. Also ever since IOS12 the app will throw you back to the home screen upon launching however it remains active, going to the app switcher and taping on it will put you right back at the home screen. Other than that it is a very accurate app and I know yall willl fix the IOS12 issues

  • New version does not seem to have visually impaired users in mind

    By AnimeGaze
    Many reviews have already pointed out the unreliability of the importing feature. For me, it sometimes doesn’t show up unless I go away from the files tab and come back to it. The fact that I keep getting asked if I want to save my document after I’ve exported it makes the process really slow. So for example, I will open a document, press save, pick a name, file type, and location, hit save, and then try to open another file, and I will get asked if I want to save the current document without closing. That seems unnecessary. I should be able to switch between files either with them auto saving or the app trusting that if I am moving away from the document I’ve finished with it. The app also seems to be slow to respond to some button press. In previous versions it would also say how many pages out of the total document it’s converted which was useful to know. Also, the app is still not integrated with iCloud. This is my main cloud service and I keep having to email myself documents I already have just so I can import them from my email. Also, more of an iPad feature but it would be great to be able to use the app in landscape mode which is as of now unavailable.. Lastly, smart invert. I am someone who likes to look at the interface of my screen and use voiceover to read the elements. Now, smart invert, that is extremely useful in every other app on my phone, turns the interface to light. I realize the app is already set up for contrast, but I shouldn’t have to turn off smart invert to use KNFB and turn it on for the rest of my phone. The reader view is slightly different because I can customize the text color and background color, but the rest of the interface is extremely uncomfortable for me to look at. A simple fix would be to double contrast the whole app instead of just the camera so that the theme stays consistently dark with the rest of my apps. The actual OCR capabilities of the app work well but the user experience is far from perfect. As a student in college that paid the full price of the app, I should have no issues with this app. But for now I am sorry to say it is not worth the price.
  • A previously great app has become a mess!

    I have not been able to get saved files to open and read and then close remaining unchanged. It seems to modify everything I had saved if I open it to find out what it was. There seems to be no way to close the file intact as it was without it being "modified" and changed in the date order, so that it is like a needle in the haystack to find again according to date it was first saved. I don't want to modify what I saved by the simple act of opening it to read it. It mostly doesn't seem to read a previously saved pdf that had obviously read easily in the past either. The OCR function which used to work rather straightforwardly like as in Kurzweil 1000, now is like a "keepaway" game. It will only warn you that you can't change whatever it does to your saved image through this next attempt to get the app to recognize an image it once easily recognized. Even if you don't choose to modify or save or even OCR what you've opened to just peek at with your ears like you could before, it becomes "modified" and it's search order is jumbled up as well as text that wasn't that jumbled before. I never saved undecipherable files to begin with. It is changing every file I open rendering it useless. I used to be able to open it, and quickly find a file and use it on the street or in an appointment or meeting. There's just no way to get that to happen now. I've just spent hours here at home trying to sort out a way to use my files again, and it's just not working. I don't have hours to try to hope to retrieve anything on the go anymore. I remember the first time I got the app maybe two December's ago how amazing and exciting it was to use in real time to read a menu, the first time out. How I could find the first recipe I saved from a pdf! I was so amazing. It wasn't broken. It didn't need to be fixed. It's like a trainwreck now. It had been expensive but worth it, even with some limitations. It has been hobbled! Makes me sad.
  • Totally disappointed!

    By mon2421
    Version 3.0 is awful! Please fix it! I am a long-time user and I paid full price!
  • Beware of most recent version

    By Walt Raineri
    The KNFB reader it originally was a very easy to use and user-friendly application for the visually impaired. With the most recent release, the functionality of the application has to graded, it is much more difficult to go right back to taking pictures of the next page, it takes 3 to 4 times longer to swipe through all the screens to get back to where you need to be to read the next page and many of the features which are never used seem to be highlighted. Beware as it is not worth its current price.
  • This APP is terrible.

    By Clfbz
    I was really hoping to find an app in order to help study for material with my reading disorder and I thought this one would be best based on reviews. However I I completely disappointed in finding that more than half of the content is either not being read or words are completely mispronounced. Besides this App being very expensive, I hope I can get my money back.
  • App for visually impaired people that was very good, is now very, very bad!

    By unhappy KNFB camper
    After latest updates, app is no longer producing reliable information. Instead of giving text, it automatically goes to PDF. You then have to switch to text in order to get that mode. And when you do that you get gobbledygook. It appears you’re now have to switch to text mode in order to get text to speech. However even if you do that, you still get gobbledygook. Fix this app! Now using seeing AI as it is much more reliable and easier to use. If I could, I would try and get my money back for this cayenne FB unreliable app. I gave this app a rating of one. However if I could I would give it a -5 because it is now so bad.
  • 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.
