Founded in 2011, Duolingo is a language-learning platform available online or via mobile apps for Android, iOS, and Windows. It offers more than 30 language courses for English speakers, including High Valyrian and Klingon, for fantasy enthusiasts. In one account, users can work on multiple languages and keep track of progress.

Duolingo is the most popular app for learning languages and is the most downloaded app in the world in the education category. The Duolingo method focuses on bite-sized short, gamified lessons, with exercises that build and adapt to what you need extra help with. One of the company's main tenets is to make free educational opportunities, so Duolingo is free. However, there are in-app upgrades to add extras, work offline, or get rid of ads.

An initial placement test is offered, if you are a continuing learner, so you will have an easier time jumping right in. Additionally, the platform offers Duolingo for Schools (still free), so that teachers can implement Duo's platform to track students' practice and progress.

Overall pretty good. Makes it fun to learn however seemed to be for people that already have a base in the language. It skipped over the alphabet and how to pronounce things and had you guess how to write sentences instead of teaching you how.

Duolingo is absolutely the best way that I’ve found to dabble in or dedicate time to learning another language. This comes from someone who took several intro classes in multiple languages. It’s worth the monthly subscription if you really do need or want to use it on a regular basis. They make learning another language fun and intuitive.

When we traveled Europe we used this app to give us active language . We enjoyed it. It was fun and interactive. It was super entertaining and engaging. Each level gives you a lot of review with semantics and grammar as well as enforcing vocabulary.

Duolingo is probably my to go app if I ever need help learning a language. Because of Duolingo, I can now read and write in Korean. I can also read some letters in Japanese and I understand a little bit of Portuguese. Duolingo is a fun way to learn a language. Although, it is hard for me to practice consecutively. I wish they had more challenges and more games to help me practice consecutively.

Duolingo has been a great platform to help me master a new language. I have used this platform for learning Spanish and Dutch, and it was helpful and fun. The style of learning was very interactive and daily goals/achievements are fun to complete and obtain. Whether you are on the go or staying in for the night, Duolingo is my favorite platform to learn a new language.

Duolingo is absolutely amazing. There is nothing else that is as good. I used to be very proficient in Spanish, but have not been able to speak it much in the past few years. Duolingo has helped me to brush up on my skills. There are speaking. listening, reading, and writing exercises. I recommend Duolingo to anyone trying to learn a new language or brush up on language skills.

I have been trying to learn Spanish for about 14 years. I have taken classes. I have used other Apps. I have tried to have people teach me. Nothing has worked. Duolingo is the closest I have gotten to becoming more fluent. I know more words and can understand more text through this app. I am pretty sure I even have the free version and that is saying something. They repeat and repeat until it is forever in your brain. I am pretty sure I will never forget that manzana means apple. The app makes you listen, talk, write and read AND if you are in a spot where you cannot listen or talk, you can postpone until you are in a better spot. I turn the app on while waiting in line at the grocery store, or while getting gas. Just quick easy moments.

Language learning apps are tricky. Will you learn rules, words, and structure for your new language? Yes. Will you learn how to speak fluently? Likely not. Duolingo has successfully gamified language learning, certainly, and to mildly successful results.

Duolingo has a great interface and plenty of languages, but I have found other methods of language learning to be more effective. Duolingo is, however, one of the most convenient and maybe the easiest software to use, which encourages consistency (which I think beats less consistent, though more effective, methods every time).

I used Duolingo to supplement my Spanish courses and the app was very east to use and very helpful in learning the language. It starts off with simple topics and works you up to more advanced topics which is extremely helpful in learning a new language. I haven't used the app in a while so I am not sure what new updates they have, but it would be cool to be able to practice with an actual language instructor through the app.

I have been using Duolingo to help practice my Spanish for around a year now and have loved it. The way it breaks things into sections makes it easy to learn and the awards and streaks provide a good incentive to practice everyday. I also enjoy connecting and competing with my friends, this has helped me to practice more and to practice everyday.

What a great way to learn a new language! It does seem to be geared towards someone wanting to travel, as they typical teach you those kinds of phrases. But I love how they let you hear it aloud and say it. It does no good to memorize words and phrases if you don’t know how to pronounce them correctly! I used it to practice my Spanish and was impressed.

My children are both learning Portuguese at their school so I've been trying to learn it using Duolingo. It is great! I love that you can hear the correct pronunciation of the language... but also see it written out. I learn so much better when I can read it AND hear it. I really like it - it's like playing a game.

I used to use Duolingo before, but now that they added in the paid function it just isn't worth it. I use Rosetta Stone instead and paid the upfront 200$, but got so much more out of it. Duolingo is okay, but I don't think you can truly learn to speak a language through it.

I tried to learn spanish on this app and it never told me how to pronounce the words, therefore I always got the speaking sections wrong and sounded confusing when I spoke. It also doesn't teach conjugation when it would be most helpful, I didn't learn it on the app and eventually gave up, if I had learned conjugation it would have been helpful
