Show HN: I built a local-first language app to track and retain words

Hey HN,

While learning Danish, I kept translating the same words over and over. I’d take notes, highlight books, save things in random places… then lose track of it all.

I wanted something simple. Translate a word, save it with context, and review it later so it actually sticks. Nothing I found really did that.

So I built my own app.

It lets you:

- Translate and save words instantly

- Add notes, tags, example sentences, gender, even emojis

- Review everything with flashcards using spaced repetition

- Track how many words you’ve really learned

- Use it fully offline with on-device ML Kit translation

I made it for myself, but once I showed it to others, people started asking to use it.

The app is live on the Play Store: https://play.google.com/store/apps/details?id=com.andr.wordw...

Would love your feedback. iOS is on the way if there's enough interest.
