Any language learning app?

Not sure if we’re supposed to provide Google answers but this looks like a reputable article from Huff Po that describes several. I’ve heard good things about DuoLingo and LiveMocha connects you with a live speaker of the language you are studying.

My daughter uses DuoLingo and likes it.

In addition to the above, there’s also Lingq, Mango, Pronunciator, and Rosetta Stone. They have apps as well as desktop versions. Rosetta Stone also sells CDs. I understand that the first two also provide native speaker help and online communities.
