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.

Ever since Ios12

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

Developer Response ,

Thank you for your review. The problem with iOS 12 can be fixed if you uninstall/reinstall the app again.

This app will bring you pain if you buy it

This app does not work. The same way all those pathetic people that work for those organizations that pretend to help blind people don’t work.
I want the developers and the backers of this app to be put in Guantánamo Bay and give him the same treatment as the most violent and dangerous terrorists in this entire world.
The developers of this app are terrorists. There are many applications that are purposefully meant to cause blind people pain. The apps are purposefully developed to be extremely annoying. Kind of like whenever you’re on Safari on your iPhone and whenever there’s a page loading there’s that chick noise that goes tick tick tick and it does it for about an hour unless you turn voiceover off and turn it back on and sometimes it keeps doing it this app does not work. I pointed at a page with only two printed sentences on it with extremely good light not too much light where there’s clear and completely still perfectly still the camera lens is clean and it does not read it properly it doesn’t even do it right I can’t even put together since right now I’m so angry right now I’m so angry right now I’m so angry right now

Not worth the money

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.
