HiNative is a fun and interactive way to learn languages. It's a sort of social network where you can ask any questions you have have about any language, while you also answer any questions you can from other users (as long as you know enough to be able to answer them).
One of the great things about HiNative in comparison with other ways of learning or asking questions about languages, is that it lets you use photos and audio files. This means you can get your questions answered by sending a voice message (this is especially useful with pronunciation problems).
In HiNative you have a your own profile where you can keep track of all the times you've helped other users and all the questions you've asked. This way you can earn points and level up.
HiNative is a great language app, that lets you help others and receive help in any language. English, Spanish, Russian, Korean, Chinese, Japanese, French, etc. You'll find tons of different languages.
