Description by Jaewhan Namkoong Written by the developer, not by AppBrain. Click to read.
LUMEN은 공부와 일상을 꾸준히 이어가고 싶은 사용자를 위한 집중 관리 및 기록 기반 애플리케이션입니다.
단순한 타이머 기능을 넘어, 하루의 흐름을 기록하고 스스로를 돌아볼 수 있도록 설계되었습니다.

공부를 시작하는 순간부터 하루를 마무리하는 순간까지, LUMEN은 사용자가 자신의 시간을 인식하고 관리할 수 있도록 돕습니다. 과목별 공부 시간을 측정하고, 하루 동안의 집중 흐름을 시각적으로 확인할 수 있으며, 기록 기능을 통해 학습 내용을 정리하고 스스로를 점검할 수 있습니다.

LUMEN은 혼자 공부할 때 쉽게 흐트러지는 집중력을 보완하기 위해 그룹 기능을 제공합니다. 그룹 내에서 서로의 공부 상태를 확인하며, 함께 공부하고 있다는 심리적 동기를 통해 꾸준함을 유지할 수 있습니다.

프리미엄 기능을 통해 확장된 통계와 추가 기능을 제공하며, 사용자는 자신의 학습 패턴을 더 깊이 이해하고 효율적인 루틴을 만들어갈 수 있습니다.

LUMEN은 수험생뿐만 아니라, 공부와 자기관리를 일상적으로 이어가고 싶은 모든 사용자를 위해 설계된 앱입니다.
하루를 포기하지 않도록 돕는 도구로서, 꾸준한 성장을 지원합니다.
