I was wondering if an app exists with alot of voice activated functionality whether it be via bluetooth or not. I do alot of driving with my job and would like something where I could tell my Galaxy to do something like "Call Home" or "text message dad" and even read messages and email to me or any kind of text. Does anybody know if something like this exists? Secondly I heard that there is an app that will project driving information(speed, miles traveled, etc) on your windshield? Does something like this exist as well?
