Update: I got an iPhone 6 Plus and the app is still The worst MLS app you can get. So glitchy! I recommend using Zillow.
This used to be a great app but has completely stopped working. I have a Iphone 5 and I have tried deleting and downloading several times with no luck. Just continue to get a lack of communication with the server message. Restarting phone has done me no good either. Time to go to Zillow or Trullia :(
