Dragon Dication by Nuance
As you can see, Dragon Dictation Free is pretty useful if you don't already have Siri, which I do not. And as long as you are in a quiet area to speak, the notes are often spot on. You do have to remember to state "period" or other sentence markers, or you will end up editing post dictation. Also, you must be aware of the length of the time you are speaking. After a few minutes of speaking, the app needs to process the information into text, which may result in the loss of train of thought. For someone with dysgraphia or the average person with an older iPhone, this speech to text app can mean improved written output on the go.
