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!

Response from developer

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!
