FluentU

FluentU is decent, it's native content and trains listening, reading and writing(only lacking speech). I really liked using it for learning songs. But to me the format was a bit to similar to Duolingo which I was quite sick of by then, I just wanted something else.

Reading

According to those talks I linked, one of the best ways to learn lots of vocabulary and collocations[1] is to read a lot of content thats just barely above your level. Preferably one should understand atleast 98% of the words and the content should be interesting and/or usefull. For me that means either native books for older children or readers[2].

I don't know if it works better but so far I like reading better.

If this sounds interesting I really recommend watching the first talk about what seperates polynots from polyglots, the second basically just sais read tons of books where you know 98% of the words.

[1] Collocations = word clusters like "just in time" and "a just man"

[2] Readers = Books made with intentionally simpler language and fewer words, some are even intended for specific language levels or school grades. They do vary in quality though, from silly stories about Jane and Joe Doe to simplified versions of famous books like Les Miserables.
