Glad to have this!
I have all the Simplex Phonics apps and think they are a great resource for any learner, but also learners with special needs. The way of breaking down components of a word with color coding etc. is very useful, as well as the clear audio for auditory feedback too. This is not a "game" as one reviewer was disappointed to find out- it is a tool. There are other spelling games that may be helpful but this tool helps the child learn the rules first, then you can reinforce through other methods.
