Iowa's caucus has been more or less working fine since it started in 1972. What was the value add of introducing an app? Knowing results sooner? Certainly not simplicity or reliability. I'm reminded of an xkcd comic (I think) where the fight to eradicate some disease is essentially making stead,y predictable progress, and a room full of developers is ready to chuck the whole process in favor of app-ification. This is that.
