App: Duolingo

1-star reviews:
content: This company is doing everything they can to make the user experience as worst as possible, and I'm not sure why. Recent change is the removal of dark mode. Before, the removal of discussions (that helped you better understand the sentence). At this point I'm waiting until they remove the ability to learn languages.
content: Cant practice to earn stars any more. Moving to other app, bye.
content: I hate it.
content: Suck.
content: Now you can't even practice for a heart. Thanks for the sparky ads, but if I wanted to pay i would use a proper language service and not this game
content: Why did you limited the option to regain hearts by practicing
content: Quả nhiều quảng cáo , app giáo dục mà toàn quảng cáo rác như tra tấn người học, bọn tham tiền mất dạy. Đáp án thì không dịch ra nghĩa tiếng Việt thì sao học được cụm từ vựng, toàn phải trên bên app khác, quá thất vọng cách dạy kiểu này.
content: Ah, Duolingo—the linguistic dungeon ruled by a psychotic green owl. It bombards you with nonsense like “The ducks are reading the newspaper” while butchering grammar and logic alike. Miss a lesson? The owl knows. It haunts your phone, guilt-tripping you like a Victorian aunt. Learning? Hardly. It’s a bizarre endurance test in frustration. A real scholar would abandon this neon-green tyranny for a book, a tutor, and the sweet silence of an owl-free life.
content: Don't waste your time or money on this app, the only way to learn now is to pay. YOU HAVE TO PAY FOR HEARTS WHEN YOU COULD PRACTICE TO FILL THEM UP. They don't care about what you have to say, your complaints etc, so saying you don't like something won't matter. Their customer service doesn't exist.
content: Why so many ads? :(

content: I recommend all beginers
content: I used to LOVE Duo Lingo lessons. I have at least 12 languages I've started learning bits and pieces of. I love so much about the app, the speaking lessons, the listening lessons... ...but I honestly can't tolerate how Co-Dependent their Duo Mascot is on the Home Screen Widget. It's actually making me feel too depressed to do Duo Lingo lessons because Duo gets SO depressed when I am going through life that keeps me apart from the app. Please cheer up Duo.

content: I don't appreciate how the translations are inaccurate. While studying Japanese and doing the word match exercise, I came across "うみ" and it was matched to "beach". Totally wrong. Even if the phrase "うみにいきます" (which is the example sentence used) can have the implied meaning of "going to the beach", it literally means "going to the sea". "うみ" means "sea". "はま" means "beach". Come on, guys. Also, "あめ" means "rain", not "rainy". Will more of this kind of misinformation crop up later?
content: Let's be honest, it's all about the money : subsciptions. The teaching content and quality has changed over time - not that it was great before, but it was there if one looked - no more grammar tips or explanations, no more comment section or discussion boards. At the free entry level one is obliged to look elsewhere for help and explanations.
content: nice
content: this used to be a 5/5 app. They took away so many features like the community chat, and they stuffed it with adds that it made it less of a tool and more of a cash grab.

content: This app is realy very interesting
content: I don't think I made an inappropriate comment. You had errors in the system and I also lost a facebook account registered on gmail in 2018 because of you. "Long and frequent breaks are the key to great success." - Romanian proverb
content: Good..... Not bad....
content: was great when it started a few yrs ago. when you paid for it, you had access to everything. Now it's 2 different paying categories. smh
content: this app is great but too much add after i finish single lesson add come
content: They've been focusing more on the dopamine provoking side than actually learning something. It's not a bad experience, but not sustainable in the long run. Learning languages by using them is still the best thing you can do.
content: App is awesome itself, BUT why there is no album orientation for tablet? Absolutly uncomfortable to study on tablet
content: Overall the apps good but I want to learn persian and it's not available 😐
content: Teaching the same thing if I get it correct
content: Good for something that is free. The ads are getting bad. I liked the first version MUCH better than what has developed. Sometimes, they don't translate the answer, it just says whether it's correct or not. There's not much learning in that. One of the guys voices irritates me so bad I have to turn the volume down when he talks. Taking away the practice to earn hearts function was a mistake, how are we meant to learn if we can't make mistakes? Lose five hearts and you're done? Stupid.

4-star reviews:
content: it's all fun and games until the listening exercises don't count your correctly pronounced numbers
content: fun just super fun but dou might threaten you because that if you don't do your Spanish lessons you vanish and it's official.Duolingo made a literal song about it called Spanish or vanish (it's a literal meme)
content: The math part is really hard to balance the number. But still great app
content: ভালো
content: this application is very best for learning English.
content: Very Helpful
content: É um bom app
content: I love this app but I wish the refill heart was 200 instead of 450
content: Good for well up english language
content: i learned a lot from it, it is really effective cause when i watch k-dramas i used to change the subtitle to English, now i removed the subtitle and understands every single detail they say.
