I have been using this app for over 3 years now after trying dozens of other flash card apps. For me it has the perfect combination of features (spaced repetition, ease of use, ability to import/export sets, good editing features, etc). I particularly like the statistics section (I have flipped 130,000 cards since starting to use it)
Lost Everything! I purchased the premium key and as soon as I did so I lost all of my nearly 200 flashcards. When I found this out I refunded my money immediately. It is not worth paying any money for a flashcards app as I've learned. What a pity!! I will go with Quizlet.
Somehow my tablet (note 2014) overheats when I use thid app. The features are great though . I recommend it. Edit : my tablet does overheat from time to time, but it happens on a constant basis with flux cards. I guess its an hardware issue which is somehow always activated by fluxcards.
I've been using it for a while, and love it. It's simple, and has the easiest method of adding decks from quizlet yet (making my own is too time consuming). I've started to study multiple decks at a time to solidify vocabulary, which makes me want to upgrade for the longer SRS period. However, when i use multiple decks, random characters/letters go missing/don't show in the cards, which makes it unusable. If i could rely on this app, I'd certainly upgrade. EDIT: I found another workaround, where I combined all of those decks into one mega-deck. Worked most of the time, and so far after using the advice below (smaller fonts), it's worked all the time.
Finally I've been looking for a good flash card app where you can draw both the answer and the question because a lot of symbols used for engineering are not in a keyboard and this does it perfectly. This has helped me a lot!
Loved it! It has been more than a year that I am using this app to learn German. I have tried several flashcard apps, and this one is the best. I create cards in Quizlet and import them in FluxCards.
Fixed LearningActivity for older devices
The fix was to remove security features that would prevent third party apps from functioning as a LearningActivity. This being possible now does not mean it will stay open for all future.
