Proloquo2go is the beat selling 2009 Medical Iphone App
“Kara Lynn has amyotrophic lateral sclerosis, or A.L.S., which has attacked the muscles around her mouth and throat, removing her ability to speak. A couple of years ago, she spent more than $8,000 to buy a computer, approved by Medicare, that turns typed words into speech that her family, friends and doctors can hear…
Still, advocates argue, advances in computing and easy-to use speech software have opened doors to use cheap mainstream alternatives. Indeed, the price drops have made it possible for A.L.S. assistance groups to buy dozens of netbooks, install specialized software like Proloquo2Go and lend them to clients.”
Interestingly enough it's not the reference apps like Skyscape but this handy app which I have never used. Still I see the need for apps like this for patients who have expressive dysphasia or any speech impairment.
