Can your smart phone really help you to learn a language?

Duolingo is a language learning app that does not charge for lessons and it doesn’t have ads. Instead it generates revenue via a service in which users practice language skills by translating articles for clients, such as CNN. It also makes money through a certification system in which users can take a test to prove their language proficiency – a multibillion-dollar industry, according to Von Ahn, to which Dulingo aims to become the gold standard.

Among the investors who have pumped $38.3m of venture capital into the company has been actor Ashton Kutcher. The investors are committed to not charging for the teaching content, says von Ahn.
