WordScreen — 배경화면으로 외우는 영어 단어 ■ 한 줄 소개 잠금화면을 펼칠 때마다 영어 단어 한 개. 보는 것만으로 자연스럽게 외워지는 단어 학습 앱. ■ 소개 하루에도 수십 번 켜는 잠금화면, 그 시간을 단어 학습으로 바꿔 보세요. WordScreen은 영어 단어와 뜻·예문을 감각적인 배경화면으로 만들어 주는 앱입니다. 따로 시간을 내지 않아도 휴대폰을 켤 때마다 단어가 눈에 들어오고, '학습' 탭에서는 발음을 듣고 알아요/몰라요로 체크하며 제대로 외울 수 있어요. 기본 제공 단어부터 내가 찍은 사진 속 단어까지, 내 방식대로 단어장을 채워 갑니다. ■ 주요 기능 · 단어 배경화면 - 영어 단어와 뜻을 담은 배경화면을 자동으로 만들어요. - 테마 색, 템플릿, 폰트를 골라 나만의 스타일로 꾸밀 수 있어요. - 내 사진을 배경으로 쓰고, 글자 색도 직접 고를 수 있어요. - 단축어(Shortcuts)와 위젯으로 단어가 주기적으로 바뀌어요. · 단어 학습 탭 - 단어 + 뜻 + 예문을 한 화면에서 깔끔하게 학습해요. - 원어민 발음으로 단어와 예문을 들을 수 있어요. - '알아요/몰라요'로 체크하고, 모르는 단어만 모아 집중 복습해요. - 즐겨찾기, 레벨 필터, 사전 찾기를 지원해요. - 예문 속 단어를 누르면 그 단어로 이어서 학습이 계속돼요. · 단어장 - 레벨별(입문·기초·중급·중상급·고급) 빈도순 단어가 들어 있어요. - 직접 입력하거나, 사진·PDF에서 OCR로 단어를 가져올 수 있어요. - Apple 온디바이스 번역으로 내 단어의 뜻이 자동으로 채워져요. · 다국어 지원 - 영어 단어를 한국어 또는 일본어 뜻으로 학습할 수 있어요. ■ 이런 분께 추천해요 - 단어장은 사 두고 펴 보지 않는 분 - 출퇴근·자투리 시간에 부담 없이 단어를 외우고 싶은 분 - 예쁜 잠금화면도, 영어 공부도 포기 못 하는 분 - 시험·여행을 앞두고 핵심 단어를 빠르게 익히고 싶은 분 ■ 이렇게 시작하세요 1. '설정'에서 학습할 언어와 내 언어를 골라요. 2. '스타일 변경'에서 마음에 드는 테마·템플릿을 선택해요. 3. 단축어로 배경화면을 설정하고, '학습' 탭에서 단어를 익혀요. 지금 WordScreen과 함께, 잠금화면을 켤 때마다 한 단어씩 늘려 가세요.
