Anybody here use the Duolingo app?

I'm a slow learner but I'm gonna use the hell out of this app in the break room just to shut down some of my old lady co-workers' conversations. Not really, but that shit is a pretty cool app that I've been messing with for the last five days. My Spanish is still worthless though. They said I'm about 4 percent fluent.
