Ratings and reviews

It works pretty well if you have a bit of a background with the grammar of the language you are studying. The downside is that the free version is really limiting you (ads + time limit), so it's hard to see the full potential before buying. And mostly, there is no Lifetime payment option, which for some including myself most of the time, is a big no no. A one time payment with a reasonable price would be worth an instant purchase !

I'm giving 4/5 because it has been annoying me that when I change a detail on an existing card from its set, the change does not apply on the card that is already in the learning process, same the other way around : it creates 2 versions of the same card. Hate this. Other than that I love this app, it is a very good tool to learning but I think it should be used along with another app/website to learn a language. Also you have to learn how to use it and make your own content (sets of cards) .

This is the best flashcard app ever. Way better than any other app I've tried, Quizlet, Anki, Lexilize Flashcards... DuoCards is the real deal. I got the premium version a few hours after getting it. Worth every cent. I can't oversell it. It generates sounds and visual clues for you to best remember the words you're trying to learn. It's brilliant!!!! Everything I am expecting from a flashcard app 💯
