Give it a chance  Blind dog Jimmy  3 star

I've got to say… This app is well worth the money… I was hesitant to purchase… But… Now… I realize I could not live without it… it takes a little patience to learn how to use it… I go through my mail… And if I have something that I am not sure about… I save it in a little pile for when my sided friends come around… this does not happen very often and makes for a much more enjoyable visit when my friends come over and do not have to spend an hour and a half reading the mail… if you have a good light and a steady hand… It works pretty good… Would recommend to anyone who cannot read with their eyeballs

I love this application. I am totally blind. I use it on a daily basis. I read all sorts of printed material. It is awesome. I would recommend it to anyone. Well worth the price.

Although it took some time to get used to, this app has already proved to be well worth the price. It has fundamentally changed the way I read.

Great app.  Wade horton  4 star

This is a great app for the visually and pay her. My only issue with this app right now, is that when you select Martha page document it does not let you type multiple pages only the first page. Please fix this problem. Will write a five when you fix them up to page document selection. Thanks.

I love this app  Jerry har233  5 star

I am a blind person for the first time ever I was able to open mail and have it read to me I am so thankful to have this app


Definitely worth the money  Subbinblazer  5 star

The user interface for KNFBReader Great compared to Prizmo. When comparing theKNFBReader app with other apps for more complicated documents it is superior. If you're scanning regular letters, thePrizmo App or TextGrabber plus translator will suffice. The advantage is thatKNFBReader Will also OCR text from the computer screen. Definitely worth the money even if you don't have any discounts by using gift cards are waiting for it to be on sale. This is not a biased opinion, it is based on comparison and experience. @TheBlindMan12v

Blind Hawaiian

Finally!!  Blind Hawaiian  5 star

If you've been waiting for the greatest OCR software ever created for the blind, wait no more!!! Best application ever!! I have been taking pictures of every thing that contains text, and it has been reading it back to me with high accuracy! Absolutely worth my $100.00


Yes, it lives up to the hype!  Scott_GSD  5 star

I have performed several scans that included different types of materials and conditions. I will tell you that no other app I have used even comes close to producing the results of the knfbReader app. I have used Prizmo, which is the only other app that comes close. Yes, the knfbReader app was designed with the visually impaired or blind person in mind and that despite what some will say is its strength. I do not believe this app costs $99.99 just to overcharge a certain segment of the population, the “blind tax,” but instead is a high-quality app that delivers on the features and performance promised. I could say quite a lot, but it really comes down to one thing and that is for you to decide if you want to work hard or work smart. Yes, you can pay less for apps that will do the job, but these other apps require a lot more fiddling to find the best position for extracting enough legible text to figure out what you got. People have used stands of all types to get the job done. With the knfbReader app you do not really need any stands etc. If you have one it will certainly help and especially when doing batches of image captures using the automatic mode. Otherwise, you can simply hold your device about eight to 10 inches above the material and nearly instantaneously get your results. I have absolutely no regrets paying $99.99 for an app that meets a need and I can remove all other apps. BTW, when I figure the cost of apps and a couple of stands I have purchased in trying to find a good solution I probably spent more than the cost of the knfbReader app. :)


Great product  Shannon_cantan  5 star

I bought it, used it, and love it. Talk about a product that is simply amazing. It's everything it was promised to be.

Crushed By Life

Best show in town  Crushed By Life  4 star

Fast, accurate, good feedback about what the camera can see, great braille support. Faster multipage scanning than the competition. The elegance of the interface and quality of results may justify the price tag if you have to deal with a lot of print. I'll give it five stars when I can pan the camera and it will alert me to text in my environment in realtime.


Absolutely Amazing!  blind_access  5 star

I have tested this on multiple documents with amazing accuracy. Works great on 5C running 7.1.2. However not good on iPod 5 gen. on iOS 8. I think it's the fault of iOS 8, not the app!


Best OCR App Out There  Steve_54  5 star

I have used several OCR applications on different platforms. Some of them worked well but on iOS, I have generally had very poor results with them until KNFB Reader came along. I stuck a regular office memo under the phone and gave this app a try and it read the memo almost perfectly on my first attempt. My camera technique isn't all that good either. So I must say that these guys hit one out of the park with this one.


supremely freakin amazing!!!  Jacalynp  5 star

wow. This single app is a life changer for blind people. it recognizes text extremely accurately and quickly. its far faster than using my flatbed scanner with kurzweil and as fast or faster than open book with the pearl doc camera. I have taken twenty or so pictures since downloading, even of my computer screen, and have been continuously amazed with the results. if u are debating getting it, don't. Its the real thing. Its what we have been waiting for! nfb and good old ray have done it again.
