Ai tutor is silly
The AI tutor is almost completely useless. It always responds with short answers, and no matter what you ask it, it basically says the same thing. You ask it to explain the etymology of a word or phrase, and it just gives you the meaning instead, simply rephrasing it. If you ask it to explain some complex language concepts, it again responds with short phrases that don't mean much. As a result, you might be paying for a premium subscription, but you still have to use ChatGPT to get comprehensive and understandable explanations. I am very disappointed with this app. While many other features work well, this particular aspect has left me frustrated.
We need this option
Hi! I really love using Duocards to learn vocabulary with flashcards. I’d really love to have an option to automatically play the example sentence when I flip a flashcard. Right now, I can hear the word, but hearing the example sentence automatically would help me remember the word much better. It would be great if users could turn this option on in the settings. Thank you!
Connection problem
The app is great. But it is annoying to see "Connection problem" every day. Daily progress can be dropped off because of the problem. But the web app works perfectly at the same time. I have tried to reach out to support several times, but there have been no results. The AI assistant didn't help. It is frustrating.
Optimization
Hi team! The app is great, i have yearly subscription but, recently, i have lost interest because of lags... They are very annoying, it freezes for several seconds, app is crashing, please fix it
I love this app ❤️
This app better that other apps and there is no so mush limits and this really helped me to learn English
Asks for review before I even try the app
How about you let me do a lesson or see your app before you ask me to rate it?
Need To Improve Marathi Language Module
The western language modules are much better developed , structured, and Colloquial while the marathi version is a disorganized (no intended structure ) . the translation being taught my family of modern day marathi speakers have to correct everything I learn off of this platform as no one uses these translations
Problem
There is always no connection to the Internet, the problem is only specifically with your application
English - Ukrainian
Translation from English to Ukrainian very bad. I have to rewrite almost every time and use another apps for translation.
My favorite learning app
Great app and useful features
Wish i never downloaded this
I wanted to improve my vocabulary by flipping through flashcards. Instead i get pushed into some analytical level setting test (which i couldn’t opt out of and just try the functionality). It makes me choose a topic of interest (cooking, travel, business) when what i’m interested in is improved fluency. It asked me a series of questions to which i responded with random keystrokes (so i could just get on with it) - and yet it “determined” i was at between 75-80% on metrics like grammar and pronunciation. Then it wanted to image my fingerprint. I’m sorry but you presume too much, your analytics are obviously fake, and your intrusiveness is off the charts. I can’t speak to the quality of the learning tool because i deleted the app rather than complete the personal information gathering inquisition. I wish i never downloaded it.
Приложение не открывается
Почему приложение не открывается? Вначале было хорошо , все открывалось и отлично помогало понимать язык , но вдруг просто перестало открываться . Попробовала удалить и загрузить вновь - не реагирует
Keep looking - this isn’t it.
DuoCards is a product without focus, disguised as a game. It contains three essential language learning tools: flashcards, a language bot, and a pronunciation coach, that are hidden behind a terrible game idea that makes the app so awkward to use that I literally bought something else to replace it after buying the family pack - and never even suggesting to my family that they use it. I think that the April 2026 introduction of Google Gemini language tools commoditized all apps like DuoCards - it is a better, more general implementation, that is free. Beyond that, there are many small usability bugs that show this app isn't very important to its maker - they didn't fix something as simple as picking a language to study on the library page. But... I did spend a bit of time evaluating the product so I'll shore some of those thoughts - from a spanish learner point of view. Flashcards: The flash card facility is as sophisticated as a college coding project. - limited information and structure - 3 blanks for text, no room for additional information like the rule to conjugate this verb. - image and translations are provided by the app - translations are adequate, images are rarely useful. - card management is nonexistent - you have a pile of cards. If you want more cards, you can add them from some existing decks, but there is no button to add, say, all 100 cards in a deck - you have to click for each one. You cannot manage the cards after they are added - like removing some when you have added too many and want to focus on a single theme, etc. There is no way to separate cards in a single deck - like providing a CEFR leveled cards for a theme. - creating decks is a second class citizen. You create your card deck in a spreadsheet and then copy all rows into the first text box on the first card. It's a hack that works OK, but I had data ingest problems that just made a mess. I never ended up using any of the 5 decks that I made. - surprisingly few provided card decks. I assumed when I purchased this app that it would have rich peer support for its sibling product Duolingo - it has basically none. It has surprisingly few provided decks as well. Use this instead: Anki. Language bot. I looked at several language apps and bought DuoCards because of the language bot - and it was a killer feature - last year. This April, I sat down with Google Gemini and some Youtubes and I replicated the feature. I actually made a more robust spanish teacher bot than DuoCards provides - and this one I use frequently to create targeted lesson plans, create infographics, summarize information along different lines than most teachers do, generate CEFR B2 story books, etc. Use this instead: Google Gemini. Search for Youtubes to set up as a language tutor - there are many. You can write a Gemini Gem to give your teacher a personality, cater responses and education to your demographic, and have it use a teaching style you thrive under. Voice coach: Finally, the voice coach is quite good. It was hard for me to find, but once I found it, I played with it quite a bit. I don’t know how you provide better textual cues for speaking than DuoCards does. I haven't seen this product's equal and it fills an important but short lived gap - endless pronunciation repetition and constructive feedback that would exhaust a human. In Spanish, I think by B1 you have full language pronunciation. In a more audibaly nuanced language like Japanese or Mandarin I could see this feature being useful for much longer. Use this instead: A human. IMHO immersion should start as soon as you can make the language sounds and learn the 100 most common words. This slow burn learning - from music, video, library conversation clubs - helps you feel the song of the language vs learning rules of language - targets procedural memory vs declarative memory.

Excellent language learning tool!
After using it for its basic, free flashcards language learning function, I decided to upgrade to the paid version. It’s a vastly more comprehensive and interesting program. In addition to the excellent space practice flashcard system, you get AI powered learning tools for speaking, listening, generating stories using newly learned to vocabulary, and a tutor. I’ve only been using it for a day now, but I am definitely going to keep subscribing.

Words I know
How can I delete words that I already learned that are already in my library list ?
Раздражает
Проблема с геймификацией. Не хватает интерактивных заданий. Но не это самое бесящее. Он стал часто просто перезапускаться, и ты заходишь и должен еще брать карточки и типа «учить» пролистывая направо. Без этого он просто скажет, что у вас достаточно карточек и ты должен их учить. А можно я сама разберусь, когда мне учить слова? Я привыкла выписывать все слова и потом уже учить. И почему он без ВПН не работает?? Его что заблокировали в РФ? Короче задолбало
Black Friday Advertisement
Your Black Friday ad won’t even let me use the app because I cannot exit the ad!! And I paid for the subscription
One of the best!
This is the app I’ve been searching for! Already has sets but super easy to add my own words! So simple to add words to my personal deck from anywhere! Bonus: it even has some videos which are great because when I don’t understand a word, I can easily add to my deck! Awesome job!
Forced onboarding /trial
I have no interest in signing up for yet another 7 day trial. Allow me to at least try out a lesson or two without having to onboard or sign up for a trial. Especially for a product with a high subscription. ZERO interest in jumping through these hoops, so I will be deleting.
Transcriptions and offline mode
Please add transcriptions to the words, it would make learning easier, and offline mode. Please please pleaseeee
xhosa
can’t hear it to learn it. “text-speech unavailable for this language combination” is the error.
Подписка
Добрый день. Хотел подписаться на приложение на год, но при подписке требуется ввести Apple пароль. Это конфидециальная информация. У меня нет желания ей делиться.
Great for beginners like me!
It’s so nice to be able to enter an English word and have it automatically translated. Creating your own flash cards is so helpful. I do wish it had a SLOW mode along with a pronunciation key….I need all the help I can get! I’ve tried others, but it’s easy for them to go too fast and make you feel overwhelmed. I’ve been using this program in conjunction with Lingopie. It’s been great!
Poor Exerience
App is useful for a while but interface is difficult to work with after original materials are reviewed. Won’t be renewing.
Buggy scum
So I bought Premium for a year, but for no reason the app started telling me to buy it again, claiming I no longer have access — even though I never canceled my subscription. And even if I had, I should still have three more months of Premium left. I contacted support but haven’t received any response, even though in the past they replied very quickly when I reported a bug. Really disappointed — I used to love this app, but this has been one of the worst experiences I’ve had with a Premium subscription
Good Flashcards, Bad AI
DuoCards are great flash cards and, for my money, the best flash card app on iOS. All thriller no killer with easy input, swipe, and auto-variation on the cards. Awesome stuff Everything else the app does, at least for a Slavic language, sucks. The AI is too dumb to be helpful and is in fact a real danger to a language learner. When I share words from Czech news apps to DuoCards to add them they remain in the conjugated form with no notes on what the nominative should be. There is no provided context about what verbal aspect a word is or what nouns class it is. The example usage is also a real mess. For example when I added the Czech word stupeň, which means “degree” as in temperature, it gave me a sentence about attaining a bachelor’s degree. That’s a totally different word, titul. It just simply isn’t possible to use this app without a dictionary app at hand and it’s AI just gets in the way and trips you up. This app would be worth double the subscription price if they simply integrated it with a Czech dictionary API. Instead they give you sludge.
Review
Have to teach grammar somehow on these apps aswell as speaking back , it’s good for vocabulary
Great!
Helps out a lot to learn new and old vocabulary so then you don’t forget what you learned. It’s large selection of languages lets you try them out a see what works for you
🤦🏻♂️
Начал обучение в DuoCards с большим энтузиазмом: интерфейс симпатичный, обещания внушительные, курс для абсолютных новичков — что может пойти не так? Оказалось — всё может пойти не так. Уже на первых двух карточках столкнулся с грубыми ошибками, которые могут не просто запутать, а сформировать у новичка ложное представление о языке. 🔴 Карточка со словом “obnoxious” Пример фразы: “The fish are being obnoxious.” Перевод: “Рыбы ведут себя несносно.” Звучит абсурдно. Во-первых, так не говорят в реальной английской речи, особенно о рыбах. Во-вторых, нет даже русской транскрипции слова, что критично для начинающих. 🔴 Карточка с идиомой “get something off my chest” Фраза на карточке: “Dory was so happy that off my chest when she spoke.” Это не английский язык, а набор слов, склеенный без грамматики. Там нет глагола, нет смысла, нет логики. Такой материал вводит в заблуждение и закрепляет ошибки. 📉 Вывод: если в самом начале курса встречаются такие “учебные” примеры — дальше можно даже не проверять. Это не обучение, а вред. Никто не должен учиться по материалам, в которых ошибки на уровне начальных карточек. ⚠️ Пожалуйста, не тратьте своё время и деньги, как я. Разработчикам — срочно пересмотреть весь контент и подключить лингвиста. А пользователям — выбирайте более надёжные приложения, где контент проверен и соответствует уровню.
Prodlem
The phrases with apostrophes don't working correct. It’s indicated incorrect spelling. But anyway, an application is great. Thank you, good job👍
Work quality is bad (mobile internet)
Absolutely it doesn’t work with no WIFI, depends on speed of internet, other things are awesome
Gets laggy when there are a lot of words
Once I had a few thousand words saved, the app started lagging and my phone got really hot. It’d be nice if the developers could make it run more smoothly when you have a lot of words. upd. Hi Michaela, Thank you for your response. This issue has been around for a long time, and DuoCards team is likely aware of it. Below are reviews from other users from 2023, 2024, and 2025: “The application is very laging. The impression is that the more words you add, the more brakes and crashes. I have an iPhone 13 pro. I already regret the subscription.” “Very good app, after add tones of cards it’s a little bit laggy after ~10 minutes of use - maybe there is an issue with memory leak? Need update to add black background instead white on ios 18 with dark theme icons.” “The app has been lagging terribly lately, I have the premium subscription and am really annoyed at how slow it’s been working and how often it crashes. Please do something about it.” Information for reproducing the problem: There are six sets of flashcards, each with about 500 words. When starting from the main screen by pressing Start, after swiping through a few dozen cards, the phone begins to heat up resulting in throttling and severe application slowdown. If the phone is charging, the issue appears faster and more severely, causing the interface to freeze for 1-2 seconds. iPhone 12 Pro Max, iOS 18.5.

Potentially Harmful & Suspicious App!!
I believe this app might be malicious and potentially uses internet bandwidth and network resources, while also creating dangerous access permissions. The issue seems to persist even after uninstalling the app from the device. I strongly recommend verifying the app’s safety. If my suspicion is correct, I’m surprised that App Store support allowed such an app to be listed. I now have no choice but to factory reset my phone. If it turns out I was wrong, I’ll come back and admit it.
Кнопка «назад»
Не работает кнопка «назад» в нижнем левом углу при заучивании слов ни на андроиде , ни на айфоне. Исправьте пожалуйста. Для лучшего запоминания слова учатся с обязательным повторением предыдущего (предыдущих) слова .
Перестало работать
Не работает приложение, перестало открываться, удаляла приложение и опять скачивала-не помогло Очень жаль, приложение очень нравилось
Great app, but gets boring over time
I’ve been using the app for over a year, and it started to feel boring… Pros: - Large library of words available through videos, flashcards, and texts - Great spaced repetition algorithm — you can just click through and learn, everything happens behind the scenes - Cool idea with the rewards and the mammoth! - Automated translation of added words (though not always perfectly accurate) - Good text-to-speech voice, with customizable options - Ability to add your own videos to the library, with subtitle translation Cons: - The library doesn’t get updated — if you have an advanced level, it gets boring - Managing your added flashcard collections is very inconvenient — for example, if I want to study a specific set - No option to practice writing the words (even though many users have requested this); the existing tool feels like an afterthought — not great… - No statistics - Too few review games — it gets boring
Almost perfect
Great visuals and great features, the only thing I would like is to be able to customize the spaced repetition.
ужасно все
нифига ничего не работает, раньше все отлично работала, а сейчас.. просто НЕТ СЛОВ!!! что произошло с приложением? почему ужасно работает???!!
Funny app
The app is good and you can learn your language if you are really dedicated but it is obviously not professional because the devs thought they could sneak in a c0ndom icon for the word liable? 😂😂
To manny adds
Learning English impossible in this ap
Bad translation to Russian
convenient application for memorizing words, but it is not clear how words become learned and how not to repeat what you already know, the translation into Russian is simply terrible, it translates literally, you have to translate in Google and then enter it into Dul Cards
best app for lean languages
i love this app
Does not work
Shows the message “Connection problem”
Issue after updating app
Hello! After updating app 11.04.2024 it stop work properly. The issue is when I need write a work or expression my keyboard on IPhone stop works and I have to reboot app.
the same words in a circle
I liked the program very much, even thought about buying a premium, but then at first I had problems with it freezing, and now I've been learning the same words in a circle for the second week and can't add new ones for even more time, it's a disgrace
won’t load! >:(
the app seems great, but it won’t load! my connection is fine and i’ve tried on both wifi and data. no matter what i do, when i open the app it just won’t load and says that if the app is not loading i should check my connection. i’ve checked my connection! it seems great so i won’t give it a one star, but this is definitely very frustrating :(
