What's New in Language Reactor

1.4.9

October 17, 2026

New: edit a saved word right from the translation sheet or the dictionary — fix the word, its translation or the example sentence without leaving the video. Cards now show the part of speech, such as noun or verb, and you can change it when you edit a card. When a video won't play, the app now tells you why and what to try. Plus a fix for a blank screen on launch, crash fixes on Android and iPhone, and smaller improvements.

User reviews

영상으로 언어 공부할 때 쓰는 최고의 앱!

기존에 유명했던 랭귀지리액터는 알고 있었는데 기능은 좋아도 인터페이스가 쓰기 불편하고 복잡한 느낌이 있어 갈아타려고 다른 걸 알아보다가 이 앱을 발견하게 됐어요. 결론적으로 아주 만족하며 쓰고 있습니다. 유튜브나 넷플 보면서 이중자막으로 편하게 볼 수 있고 모르는 단어 누르면 뜻과 함께 AI 설명도 볼 수 있어요. 제일 맘에 드는 부분은 바로 플래쉬카드로 복습할 수 있어서 안키에 따로 안 넣어도 돼서 편리해요. 무엇보다 디자인이 깔끔해서 눈이 편하고 군더더기 없이 너무 좋습니다. 아직 초기라 기능상 아쉬운 부분이 살짝 있지만 피드백 요청 드리면 빠르게 대응해주셔서 앞으로 더 좋은 앱이 될 거라 생각합니다. 언어학습자분들께 추천합니다!
