Most vocabulary apps stop at recognition. You see a word, tap the right meaning, move on — and then freeze the moment you actually have to use it. Sentence Monster makes you write. Each session gives you short sentence prompts picked from your own learning history, checks what you wrote, and brings back the words you missed, half-remembered, or still can't use confidently. The review schedule is built from your actual failures, not a fixed interval. 15 languages. Free to start.
