Dualingo

Duolingo is a free language learning app that has quite many different languages in it. Duolingo is really good for beginners and it’s also good for pre-intermediate or lower intermediate learners. 

There is an option to either start from scratch with every language or you can take a shortcut if you know a little bit of the language and you can test out the different modules. Each language of course in Duolingo is organized into modules which are in turn made up of lessons.
