DAI RISPOSTE - Français

Duolingo
I haven’t had an online app for train a language before Duolingo
but I am trying to learn French and I could learn French with that very well and I am really satisfied
you can try to learn not only french but Chinese, russian, Turkish, Spanish, ... also
that great
really great

I can strongly recommend you LingQ. Even though you don’t have full access without paying, you can work around it.
Another good way is to use Anki for vocabulary. I personally don’t really like Duolingo, Babbel etc. since most of what you learn will not be of use. The ridiculous thing of being able to express your feelings about polar bears before knowing how to ask for directions and stuff.
