The problem
Most flashcard apps either lock useful language pairs behind a subscription, ship a word list too small to be useful, or make you re-review words you already know every single session.
The approach
Built a 668-word bank ranked by real frequency across four languages, added per-pair progress tracking that remembers which words you've learned and can focus review on the rest, and wired up text-to-speech — native on Android, Web Speech API in the browser — so you hear pronunciation, not just read it.
The result
A flashcard drill that remembers your progress and speaks the words back to you, in the browser or offline on Android.
