Has anyone tried Mango Languages for Latin? What was your experience?
I found it missed the mark.
Mango is designed to teach you phrases in the language. It works well for spoken, living languages. Its Latin course teaches you to recite some lines from a few different authors. It doesn't teach you to read Latin or to speak common phrases. Learning to read those lines out loud is good for pronunciation, and to get a sense of how Latin is structured, but in the end, it covers very little content.
If you have access to it through your library, then I'd say it's worth a try, but I would never recommend you pay for it just for the Latin.
I haven't used it for Latin yet, but I have been using it for Hebrew (finished modern Hebrew, slowly working through biblical Hebrew) and think it is an excellent program. The app/site itself is really well designed with features like colour coding (I love this as a visual learner) ability to toggle between literal and natural translations, an autoplay feature on the app so you can listen to it more like a podcast. Grammar is taught less systematically than on duo but is introduced bit by bit. If you can get free library access (just enter your library card number on their website to check) I say try it out.
Several months ago I took a brief look. The course goes through adapted passages of Roman authors--Caesar, Cicero, Phaedrus, etc.--and make little exercises from the passages.
It is an attempt to meld beginner material w/ full-blown (if adapted) Latin text. My impression was that for a beginner there just plain wouldn't be enough repetition, but it might provide good supplementary exercises. However, I did not spend much time with it, so take this with a grain of salt. If you can give it a try w/o paying for it, go for it!
Are you looking for a follow-on to the Latin course? People will be recommending Lingua Latina per se Illustrata, by H.H. Ørberg and it definitely would be a good continuation. So would the Oxford or Cambridge Latin courses (although that is just an impression, as I haven't worked through them). So would many of the traditional grammar-translation courses, if you like that kind of method, many of which you can find online with answer keys. What are you hoping to do?
Kind of OT, but FWIW I have a Russian introductory Latin book called Latina Viva, which starts out w/ Caesar in somewhat the same way as Mango Languages does. I'll append a couple of page photos to show what it does, when I have a chance. [Added: if anyone should want such photos, I can still append them. I'd forgotten all about posting this.]
