App of the year
I'm studying French and I love the translated dialogues they have at the end of many of the units. They use native, non-robotic speakers and speak at a natural pace so you can hear the linking of words.
I love how easy it is to use, and how amazing the community is. The lessons are designed very well and the app is extremely easy to use. Just pick a language you want to learn and let the app guide you the whole way through.
No matter the language you are learning, it teaches you actual grammar concepts and how to use them, which I find remarkable.
