Word Modulator is specifically designed for children having difficulty learning sight words, numbers, and letters. This app runs through all the fonts and styles available on your iOS device to generate constantly changing words from user generated dictionaries. Using left and right swipes to discreetly mark a correct or incorrect reading of a word, results are recorded for later review on a per-word basis. User controlled dictionaries can be used as a basis for different review sessions as well as for professional therapists to create different sessions per-child.
