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!

Thank you for sticking with us! ❤️ We completely understand the frustration about waiting for offline access — it’s something we really want to bring to you too. We’re working on it, but to be honest, it’s turned out to be more technically complex than we initially expected. We’re doing our best to find a reliable and smooth solution.

best app for me to study words

я попробовал очень много способов как учить иностранные слова, но только в этом приложении у меня получилось РЕАЛЬНО выучить больше 1050 слов/фраз на английском и больше 600 на итальянском (учил в 2025, запоминал реально быстро и эффективно) Конечно если сюда не заходить, то весь словарь забывается, но это проблемы нашего мозга, а не этого милого мамонтёнка. всем мир

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.

Супер!

Отличное приложение, удобная система карточек для запоминания, есть курсы для изучения грамматики(не по всем языкам), будет круто, если добавите грамматику турецкого, спасибо!

Thank you for your wonderful review! 😊 We're happy to hear you're enjoying DuoCards. As for the suggestion about adding Turkish grammar - we'll pass it on to the team for consideration. Happy learning!

Excellent when it works

Probably the single best and most easy to use flash card app I’ve ever used. I find its tools very helpful. I only wish that I could adjust the pronunciation on cards since sometime the AI picks up the wrong pronunciation for certain kanji. In addition, I seem to get “connection problem” error messages often no matter how good my signal is and I suspect it has more to do with something on the app’s back end than it does the user. It would be great if that could be worked out.

Thank you for your feedback. We're glad to hear you enjoy the app overall. Regarding pronunciation, its quality is still limited by the capabilities of the underlying AI models. As for the connection errors, we're sorry for the inconvenience. We've sent a fix there, so it should work better.

Excelente

O melhor app de flashcards. Não achei nenhum como esse. Pode colocar frases de exemplos e imagens. Também tem a opção de falar ou digitar a frase. Muito bom!

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

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 ?

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.
