What is the KNFB Reader app and what does it do?

The KNFB Reader is a print to speech application that runs on your iOS or Android mobile device. The app enables the camera to take pictures of printed material, rapidly convert the images into text, and read the text aloud using high quality text-to-speech, TTS. Recognized text may also be read using a connected Braille display.

On Android, BrailleBack should be installed on your device. A list of BrailleBack compatible Braille displays can be viewed on the Google Play Store.

What devices will the KNFB Reader app support?

The KNFB Reader app for iOS will initially support the following iDevices.

  • iPhone 7 / 7 Plus
  • iPhone SE
  • iPhone 6s / 6s Plus
  • iPhone 6 / 6 Plus
  • iPhone 5 / 5s / 5c
  • iPhone 4s
  • iPad Pro 12.9" / 9.7"
  • iPad Air / Air 2
  • iPad mini 4 / 3

KNFB Reader for Android: due to the large quantity of Android devices available, it is difficult for us to list all compatible Android devices. Here are recommendations on hardware and operating system version which will ensure a greater likelihood of a successful experience:

  • Optimal experience: Android device with a hexa or octa core CPU, an 8 megapixel camera, and Android 5 or 6.
  • Less optimal (KNFB Reader will run, but you will notice reduced speed and accuracy): An Android device with a 1.2 GHz quad-core CPU, a 5 megapixel camera, and Android version 4.3.

KNFB Reader for Windows: KNFB Reader for Windows is a Universal Windows App. It requires Windows 10.
In order to do anything beyond recognizing image files with the app, an image capturing device is required. This could be a document camera, a flat-bed scanner or even the built-in camera on the back of a phone or tablet.
Not all cameras are created equal, you will have better results if the camera has auto-focus, takes pictures of 5 Mega-pixels or more and includes a flash.
Other factors, such as processor speed and available Ram will affect performance.

If I previously owned a Symbian mobile reader license or a knfbReader Classic, can I get a discount on the purchase of the KNFB Reader app?

Due to the change in hardware platform, we will not be offering any discounts on the KNFB Reader app.

Will I need to pay for software upgrades?

At this time, software updates will be free unless the updates include major functionality or enhancements.

Will there be an option to obtain additional reading voices?

We are considering adding alternative text-to-speech voices as in-app purchases in the near future.

Can the KNFB Reader app be used in an airplane?

Yes. The iDevices which support the KNFB Reader have an “airplane mode” in which the cellular functions of the device are disabled, allowing the app to be used safely during flight. Just remember to be respectful of your seat mates when using the flashlight or the camera flash.
