Hello! I've been on Duolingo for some time now, and I think it's great, but I don't think it's enough. I've been trying to find some other tools for language learning. (not to replace Duolingo, but to help out in, for example, the vocabulary department) So far, the only good one I've found is AnkiDroid. It's really helpful, but I think there are better ones out there.
Does anybody have suggestions?
PS. The languages I'm trying to get better at are German, Swedish, Esperanto, and Russian (and maybe Norwegian, although my Norwegian is pretty strong already), but you can leave suggestions for other languages too, because other people might find them useful.
Two resources I would really recommend are:
Clozemaster – absolute beast when it comes to vocabulary, it killed Anki for me completely and it has wealth of languages, some of which are really hard to find resources for, otherwise. Clozemaster's vocabulary groupings based on frequency can keep you occupied even at C2, so it's a great vocabulary resource for everyone, IMHO.
Conjuguemos – great for grammar practice, especially when you base your language study around Duolingo, as grammar is definitely the weakest spot of Duo.
