Recall: Vocabulary Trainer

Recall builds flashcards from whatever you're actually studying: photograph a vocab sheet, textbook page or handout and it reads the layout, then rebuilds it as structured cards with senses, examples and pronunciation, catching duplicates before they land. It runs on FSRS to track when each word is actually slipping from memory, rather than reviewing on a fixed schedule, and resurfaces it in your feed, lock screen or audio. Every card keeps its own language pair, so Japanese-German and English-Korean cards can sit in one library, with the interface in nine languages and AI feedback in whichever one you read best. It's free to start, on iPhone.
