I'd like to learn Latin here, on Duolingo, but it probably won't be created. So, is there any application or site teaching it?
Luis said they have to prioritize what languages go into the incubator, and the process isn't very organized. He also said that the want for Latin is Noted.
So we may get it sometime :) Source: https://www.reddit.com/r/duolingo/comments/5pr3sv/i_am_luis_von_ahn_ceo_and_cofounder_of_duolingo/

The book that I would highly recommend is Lingua Latina by Hans H. Ørberg. It's the one that I use for school and it is amazingly useful.
This Youtube Latin course has 170 videos.
I have seen Latin on memrise. I haven't used it because I learn Latin in school, but memrise is usually very good with languages. Hope this helps.
Great question. Here are a couple fairly recent discussions about Latin on Duo post 1, post 2. And here are some discussions w/ suggestions for learning material post 3, post 4. (There are some sites mentioned more than once). This has been discussed plenty on Duo. Just in my bookmarks, for instance, there are more than 200 discussions.
