App Overview & History
• What it is: Originally called KNFB Reader (short for Kurzweil–National Federation of the Blind Reader), this highly acclaimed mobile OCR (Optical Character Recognition) app turns printed text into speech or Braille, designed for users who are blind, have low vision, dyslexia, or other print disabilities.
• Origins: Developed by Ray Kurzweil in partnership with the National Federation of the Blind, the first iteration ran on a PDA with a camera and was priced around $3,495. It later supported Nokia Symbian phones for around $1,595.
• Modern versions: In 2014, Sensotec ported it to iOS at a much reduced price (~$99), followed by Android and Windows versions.
• Name change: In 2022, KNFB Reader was renamed OneStep Reader under Sensotec’s development.
