Building a vocabulary app inspired by collectible card packs

I’m building VocaPack, a language learning app where learners open packs, collect vocabulary cards, and review words through simple game-like interactions.

The goal is to make vocabulary practice feel more fun than studying word lists, while still keeping it genuinely useful.

You can find the app on play store.

I'm working on app store relaese.

Would you use something like this to learn new words?
