Pros
Pro Motivates through creative gamification
Progress is measured gaming-like by gaining XP, and leveling up. They use other creative gamification techniques to keep you motivated such as making wagers and improving your position on the leaderboard.
Pro Generous free plan
Duolingo is completely free to use, with no features limited to upgraded accounts. If you want to go ad-free, the cost is $12.99/month.
Pro Super easy to use.
Very intuitive app. It has the kind of "intangible" user experience that simple feels better than the others.
Pro Has a mobile app
Pro Friendly, active community
There is a discussion board available on the site, and a really active community on reddit in r/duolingo (30k + members). Everyone is friendly and happy to help or offer support.
Pro Extensive
Duolingo is exceptionally thorough when it comes to teaching the nuances of language. It has plenty of audio material, articles to translate, and a cooperative development made by users.
Pro Engaging learning method
Each lesson uses a variety of different learning methods to keep it interesting and fun.
The lessons are short so you aren't forced to focus for long periods of time.
Pro Frequently adding new languages
You can check out the courses page to see what languages are "hatching" (being developed) and what languages are in beta.
Pro Gain experience writing in your target language
Where many programs will have you writing single sentences at most, Lang-8 encourages you to write short stories or diary entries.
Having to actually write in the language rather than simply remember vocabulary is a really beneficial feature for improving real-world use of the language.
Pro Get feedback from native speakers
Native speakers of the language you are learning will give you pointers on your writing, such as grammar corrections and advice on word choice/sentence structure.
Pro Self-directed learning
Write as much or little as you like, about the subject of your choice, at the level of difficulty of your choice, taking as much time as you wish. Intermediate and advanced learners can benefit the most from this, but beginners can still use the site to practice what they've learned elsewhere.
Cons
Con Mobile app is less beneficial because it's too easy
Some of the games available on the mobile app are different from that on the desktop version, and are oversimplified/make it very easy to guess.
Con Little production of target language
Duolingo focuses heavily on reading comprehension and translation into one's own language rather than encouraging production of text/speech in the target language.
Con The hype in the community creates false ideas about what level Duolingo gets you to
Duolingo is a good tool for a beginner, and a good supplement to other resources. But it cannot get you from zero to understanding natives, tv, and books; and their "do the reverse tree and just speak" is usually not the correct answer to "what should I do after finishing the tree".
Con Tediously repetitive with not much advancement
Not good choice for brushing up on a rusty language. Teaches through constant repetition of same few (very basic) words over and over. Little progression. Range of vocab and grammar very limited. Tedious in extreme!
Con Counting only on Duolingo is a waste of time
Con Repetitive questions on entire lessons
Same questions all over until one section completed.
Con Doesn't take you to an advanced level
Con The health system on the IOS app disrupts learning
5 mistakes and you're out, unless you pay, wait several hours, or use a special review that currently doesn't let you choose what to review. Especially terrible if you're learning multiple or more difficult languages.
Con Available languages are predominately European
Duolingo teaches 23 languages from English at the moment: Latin American Spanish, French, German, Italian, Portuguese, Dutch, Swedish, Irish, Turkish, Danish, Russian, Norwegian, Esperanto, Ukrainian, Polish, Welsh, Greek, Romanian, Hungarian, Hebrew, Swahili, Vietnamese and Japanese (the last currently only on the app). Popular non-European languages such as Mandarin and Arabic are not currently available (although Korean and Indonesian are in development).
Con Dangerously addictive
Con New sign ups are currently put on hold
They are not accepting new registrations now, and it is not clear when will they accept them again.
Con Not a good starting place for beginners
The site doesn't teach you your language, instead it allows you to get advice on your writing in your target language. It's better if you have a basic understanding of the language at first.
