In case you don't know what I'm talking about, Duolingo is a completely free app available on web, ios, and android. You can check it out at Duolingo.com. Its format is similar to that of Rosetta stone, but, of-course it's free, so it's not nearly as sophisticated. Just so you know where I'm coming from, I have 4 years of French from high school, so I'd consider my skill range from intermediate-novice. I haven't taken the language since high school, which was back in 2008, so needless to say-- I've become a bit rusty. Since I've started using the app this January, I've noticed a huge increase in my vocab, but not so much in my listening/conversational skills. If you’re looking to achieve fluency, you’re not going to do it solely through Duolingo, but it’s certainly not going to hurt. The convenience that the app affords lets you work on French no matter where you may be, whether you’re at the doctor’s office, on the toilet, in church, or playing on your phone in French class. I’d like to hear if you more experienced guys have tried the app, and what you’d have to say about it, so please let me know! (PS- If you’d like to add me on Duolingo, my username is ‘duct’… I’m up to level 9! :-D)
