Good idea to have this app. The menus are fine; good organization. However, details like actual work submitted or feedback are missing. I don’t think it goes through any testing before deployment. It is riddled with obvious bugs. For example, the grades under Assignment are updated; the grades under Grades are not, even after forcing an update. There is no mechanism to submit bugs; hence, I am using this review (hopefully, someone reads it)
This sucks
Absolutely love it
This app just gets worse and worse every day. I’m over it, won’t be renewing my subscription
NOT appreciated. Makes me want to get rid of my whole subscription except I’m up to level 16…
A lot of people can’t pay all at once for a big discount but still want to use your product. I think it would be conductive to make the monthly payments more reasonable in comparison. Something that still gives the incentive to purchase the yearly plan.
Love ittttttttt
I absolutely love duolingo! It helped me learn so many different languages. The only bad thing is the streaks, the will somehow get upset if you loose your streak and gets a little annoying. In general this app is great!
I learned Spanish
Good but demanding serh gut
Good but you gotta pay to do it for more than 10 minutes
Unbelievable how good duo is at teaching us
If you’re paying just ignore but if you want to use this app for free just skip. I can’t handle another 90% completion with almost no mistakes just to be told to pay money or restart and wait. That and I don’t think I’ve learned very much in the YEARS I’ve used the app. Uninstalled forever, switching back to rocket…
It’s a great way to learn but once you want to go delete it it won’t let you
I love it but when I lose all my hearts there are a bunch of ads like Bru sorry if offended.
I was and still am struggling with the same hacker situation I was having three years ago. Unfortunately for me, when I actually had this app on my desktop and it didn’t just look like I had it on my desktop, the notifications became a bit personal and intrusive. For instance, one of them said they had gotten enough of my practices recorded that they could make it look like I was doing all sorts of things. Perhaps the words are exactly the same, but nothing I have just said is exaggerated in any form or fashion, and it is the exact meaning of the point they were trying to get across and caught on surveillance tape talking about when I could not hear them. Just mentioning it, because whoever it was might’ve had a different idea for the company than the people leading the company? I didn’t know what was happening back then, but if that had happened now, I would have suggest the company contact the FBI or their internet crimes division. Because, they might have been a bit more than happy
used to be actually helpful and motivating when they had a heart system but they replaced all their employees with ai slop and changed it to energies which only get you about 2 free lessons and you have to watch ads to get more energy this app is quite literally pay to win if you have a subscription then you get unlimited lessons and they push the subscription constantly with their ai ads when they used to have unlimited lessons when the company wasnt so money hungry and blatantly full of corporate greed.
Love the app itself but this app icon right now is very ugly. It doesn’t change anymore after you do your streak for the day. It’s just an ugly sweaty owl. At least make it an option to pick an icon or change it
It’s okay🙄
Do they even know what music is? They apparently don’t. What’s tempo to them? A light suggestion. They also only teach treble clief, and I play the bass guitar hoping that I would able to learn bass clief. I don’t even think piano uses treble clief, it’s a C instrument. They aspect you to instantly be able to site read on the spot. They only let you read a measure ahead. That’s like giving a baby a fork and aspecting them to know how to use it. Just stick to teaching languages.
Seriously I’m sick of staring at the most heinous app icons. Duo is a funny character but sometimes it’s just borderline nasty. I’d love the option to change it or turn off the insanity. It makes me want to hide the app, and consequently stop using it.
i am over 80 years old and found the subject matter inappropriate or uninteresting for my age. I love Lily and the general approach to the language but don’t care about the competitions.
I learned languages, easily math music. I love this app. Thank you the owner.
Good
This is obnoxious and there doesn’t seem to be any way to avoid it. I try to do Duolingo quietly at night for example and suddenly the sound is blaring when I try to get through video exercises. Respect the volume level that I’ve set, please!
I like duolingk but a couple months ago they randomly began making everything vibrate like crazy. I usually like some vibrations to notify me of stuff but every time i do a lesson on duolingo it hurts my hands ow im in agony help
This app seemed fun for me to use to learn a language on my free time while I work getting my passport together. This app is predatory, claiming a “free” month and then after billing you or something. And it charges you right away. I am currently disputing this charge after cancelling this FALSE trial. Do not download, it’s all AI slop.
I like you should teach sign language too I feel like that would be really cool, but I do love Duolingo either way it would be really cool.
I primarily use Duolingo to study Japanese, and I’m concerned about the accuracy and consistency of the AI-generated content. I’ve noticed recurring pronunciation errors, particularly with は. For example, in から離れます (kara hanaremasu), the は in はなれます should be pronounced “ha,” but the app sometimes pronounces it “wa,” as though it were the topic particle. This is especially frustrating in a language-learning app because learners may not yet know enough to recognize that the pronunciation is incorrect. I’ve also encountered confusing translations that seem to ignore the context of the lesson. For example, while learning the words for “niece” and “nephew,” めい (mei) was unexpectedly translated as someone’s name rather than “niece.” Whether this is an AI error or a design choice, it disrupts the learning pattern and makes the lesson less reliable. I enjoy using Duolingo, but these kinds of errors undermine my confidence in the material. I’d like to see stronger quality control for Japanese p
Streak freezes being used even though the lessons were done and it showed the next day on the dashboard, only to be missing the next day and a streak-freeze used! 3 in the past two weeks! Fix it plz!
I really do feel like Duolingo is really good for all languages pacifically for me Español Spanish. It’s been teaching me a lot about my language my culture. Just in general, my native language and overall just a really good app to help you learn your I guess I would say in my opinion your native language who you are if you want to learn it is really helpful for that
I didn’t succeed learning Chinese Mandarin with Duo Lingo. Now attempting to study Spanish. I’m an adult, so all the extra rewards BS is actually annoying and a waste of time for me. Also, from time to time I get into a flash-cards competition (without me understanding how I get there), and if I don’t go fast enough at the most advanced levels the app asks for some ransom money to not erase my progress. That is quite upsetting as I have already paid over $100 for a year. That should keep the wolves away, don’t you think? There’s also too much typing required on the tiny phone keyboard. Why not let me say it more often?
Amazing
Since Duo changed to AI-generated, I have hated it. There is no connection to actual people, and the learning development is inconsistent. I paid for SuperDuo for many years and hate to abandon my 2286-day streak but today’s single lesson makes me want to comment. In French, is “situation” masculine or feminine??? In one incorrect answer I was explained that it is masculine (use “ce”), in another I was told it was feminine (use “La”). In the same lesson. This inconsistency is one of many things I have not liked about the new learning design. I’m glad I quit paying for it a month ago. I only keep using it daily because it tracks my streak, but it is no longer very effective for actually learning a language. Update: I still use DuoLingo and am near a 2500-day streak. I can’t stand the AI-generated content and disconnect from what is being taught in one part and what is evaluated in another. And today I asked to explain my correct answer and it glitched, the only thing I could do was to a
I always avoided paying and now it jumped into a demo and will not let me out boo!
I tried a different app first, but I like this way of learning better. I enjoy the flashcards an I think the AI interaction is much more life like and helpful! I definitely recommend trying Duolingo first! I would like to suggest to the makers, some actual conjugation lessons would be nice. Also, to maybe skip areas of non interest and come back to them later. Talking about skiing is less important than the months, days or numbers.
It’s awsome
Overall, decent app for practice. But the rating of answers is ridiculous sometimes and downright incorrect.
There should be no lgbtq themes in a language app. Disgusting I will not be re subscribing to this garbage
Everything is okay but when I reviewed my chess match, it said i could’ve eaten a pawn with my pawn, but there wasn’t even anything to eat. P.S., u should make oscar better at chess.
However learning sentences structure is inferred, rather then taught.
Игра прекрасна
Siempre me gustó mucho esta app, pero con eso de que necesitas energía, solo se puede hacer una lección al dia y no se aprende mucho, pero se que ahora todo el negocio
Duolingo has been helping me all lot
Duo is amazing if you wanna learn a language try it
it’s been so good for my Spanish in my vocabulary and improve me a lot so I know a little bit of Spanish but I’m improving every day if you’re looking at this get it this is so awesome
Every once in a while an app just makes you wish you could slap the developers on the face and ask what they were thinking. Having no way to add energy aside from gems or purchasing the subscription was the first thing to do that with this app. Then they had an update where instead of getting five energy after a streak, it randomized the amount of energy you get. How is that helpful to anyone?! It adds nothing but frustration, especially given the first problem I had. Made me want to slap someone all over again. Then there’s the extremely weak teaching this app does. If you’re just trying to learn some phrases or if you’re in a class while using it, then it’s fine; but if you actually want to learn the language, this app fails. Even worse it will throw you into exercises with words you’ve never heard before with no help. Don’t get caught up in the hype
Best app for learning language in free
There’s already a speak option, and I don’t want to stop and spell, I want to practice being able to pick the corresponding word out of others on display, like it was before, so I can practice cementing the word in my mind. It was an unnecessary change, and the push for speaking the words seems like an attempt to get users to train ai without realizing
I lov to talk with lily and learn new words because I'm starting to grow up and the fast I learn them the better I get and because half my class speaks espanol
