Hate waiting? Especially at the Emergency Room? There's a FREE app (FastERTX) for that, courtesy of iPhone Life's own Medical blogger, Harvey Castro, M.D.! The app serves the Dallas / Fort Worth area, but it's a great idea that should be available everywhere.
FastERTX is currently in top 100 medical apps and helps DFW patients find the local HCA hospital, wait time, call hospital, website to hospital, list and map views plus driving directions, using your gps location.
A local (Texas) TV station demonstrated the app here: http://www.youtube.com/watch?v=gbWGHa8gixM
