KNFB Reader App Details

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. Need nutritional information from your breakfast cereal? KNFB reader can read labels. Out shopping and need a price? KNFB Reader can read price tags. Want to know what came in the mail? KNFB Reader captures it all. KNFB Reader captures print from your computer or tablet screen. Photograph the screen and know exactly what that error message says. Little details abound.

  • Not worth the money

    By No Vision81
    This App has never read a document for me flawlessly. It always reads it in jiberish which means it isn’t recognizing the text (I have a iPad Air 2 and an iPhone 7. I always have a light shinning on the document to ensure enough light is on the document since I learned the iPad Air 2 has no flash). I thought paying $99 for an App would mean it would work better than a free App or one much cheaper. Get what you pay for, Right? Not in this case. I purchased a free App that does much more than this one does (Reads documents, handwriting, colors, detects light, scans barcodes to tell you what a product is, recognizes object in your surroundings and does facial reconition). The first time I used the free App, It work flawlessly and red a complete document to me. It also photographed the document automatically once it was in view of the camera. I use that App more than this one. The only reason I still keep this App, Is to tell me if a page is upside down (That is the only good feature about this App). Don’e waste your money on this App. Especially if you can’t see like me and need something that will work well and consistently.
  • why is it designed this way

    By MV-3864-6100
    I recently downloaded (AND PAID A LOT OF MONEY FOR) this app to use for assistance in reading books. There seem to be so many poorly designed aspects of this app that are making it tedious to use. 1. When I photograph multiple pages and allow them to process, then try to add more images to the existing file, I can only do it one image at a time. 2. The automatic photo feature just does not work, period. 3. Half the time in manual photo mode using the volume buttons fails to work to take the photo, but at random times it does work. 4. If I photograph multiple images and allow them to process, then go straight into listening to them, the reading accuracy is much higher as the app reads directly from the photograph. However, if I close the app or switch files for too long the images convert into PDF-looking files and much of the text becomes gibberish. 5. The incessant refocusing in the camera app is frustrating because I have to try to time when I press the button, or else it takes a blurry photo. 6. Only one voice option. 7. Button symbols are bizarre and difficult to understand, I don't use any other text-to-voice converters so I only have the visual cues. 8. It is difficult to upload a file, I still cannot figure out how. I've only had this app for four days and have already run into so many issues. Why does this cost $100 if it barely functions? I'm a poor grad student.
  • Horrible....just horrible

    By Agodlessdeath
    Horrible. What happened to this app? For some reason I cannot change the English voice to anything but Fred. I am not impressed with the new user interface either. I can use it however it is not as straightforward as it use to be. it just seems cluttered. I agree with other reviewers that saving files and importing them is needlessly more complicated. My biggest complaint with this app is the fact that I can only use Fred using English. There is no way I would pay full price for this app now.
  • 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
  • Unreliable

    Unreliable needs lots of work

  • 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!

    By waterdiva
    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.
