This is a fork of FloFla Cards by flofladev.
The original idea and base implementation are theirs. Using Claude, I implemented significant new features on top of their work.
CardPop helps you learn passively while using your phone. Flashcards will appear on top of other apps at intervals you choose – so you can memorize words, formulas, or definitions while scrolling, chatting, or browsing.No extra effort. Just daily learning in the background.
- Learn new words daily while scrolling social media
- Revise definitions before a test
- Practice foreign languages without opening a book
- Build your own library of flashcards for any subject
- Students and high schoolers preparing for exams
- Language learners who want to expand vocabulary

- Unlike other flashcard apps, CardPop doesn’t require you to open it every time. It gently reminds you of what you want to learn while you’re already using your phone. Simple,effective, and distraction-free.📌
