I have been using this app since it was released, and they have incrementally made it better and better. Having said that it does take a good amount of time and patience to get setup, but once you do it is solid. My wife and 6 year old have no problems using the screens that I have created. My son can even explain it to his grandparents.
I have a multiroom av matrix that was incredibly complicated to setup, but like I said you can use this system to make it easy for the rest of your household to use.
