This is a great multi purpose app. I use it to teach spelling, segmenting words and phonemes. I was a little confused at first,because I thought the app word say the words once it's put together but what you hear are the individual phonemes that make up the words. Ex: night when spelled n-igh-t, gives the 3 sounds in the word. Great for words that have a long vowel and a silent e ex: l-i-k-e use mr.i and magic E and u have the word sound out. Perfect for my prince.
