Busuu is a nice and useful app i came across, which animates people to learn new languages, or to refresh already existing language know-how with the help of a huge community of native speakers. The app is available for all major smartphone and tablet platforms and it allows you to train a multitude of different languages and to check the results with thousands of native speakers worldwide. Learn directly from native speakers of the busuu community via integrated video-chat application, or practice your language skills in a live conversation. I checked the french language app for myself and i really liked this simple and intuitive approach. The base version with starter courses is free, the pay version offers additional courses and more features. So check it out for yourself and learn a new language fast!
