Pro Meet and chat to cultures all over the world - A proper global society
So much better than facebook instagram, able to share experiences, knowledge. Imagine how the worlds troubles could be resolved if you all understood one another more effectively, able to engage and understand culturally the differences that make us all different. This goes a lot further, as you are actively seeking to converse with people you other wise wouldn’t meet or have anything in common. In this case the thing we have in common is the will to engage and understand our weaknesses in this case the language barriers.

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.

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.

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.
Cons
Con Some "unfair" benefits for "pro" members
Con Limited access to built in translation tool can be counter productive for beginners
Limited access to built in translation tool, even though it is a google API that powers it, which as we all know is called google translate. I had to finish a conversation part way due to the limitation of the free version and using (said had translated to many times - WTF) the translation tool. Seems a little counter productive, especially if you are new to a language and sometimes both parties need the support to get off the ground.
Con Infinite waiting period
Con iPad version doesnt resize to landscape version only works in portrait mode
iPad Pro doesnt resize to landscape version because the app is made for mobile phones (which is great if you are on the move, but useless if you are studying).
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).
