It's really easy and fun to use; I'm currently using it to learn Spanish. They have an iPhone app as well (that's what I'm using) and they have even more languages to learn (for free!) than are listed above. I highly recommend it.
You can watch every single old Disney movie for free! The movies are broken up into several videos though-kind of annoying but if you don't mind clicking on them every few minutes, you can watch them all.
