도파민 중독 탈출..

쇼츠 보다 맨날 늦게 잤는데 멜리토닌 덕에 이제 일찍 잡니다!

Response from developer

앞으로 자기 전 쇼츠 차단에 멜라토닌이 도와드리겠습니다!

삶의 질 개선

평소에 자신의 의지를 믿고, 하루를 열심히 살은 나에게 보상개념으로 자기전에 잠깐 킨 핸드폰이 10분 20분 30분이 되며 늦게, 어지러운생각들로 잠들던 일상을 막아주고있는 앱.
잠기면 불안이 느껴지는 내자신이 그동안 어떻게 살아왓는지 되돌아보게됨

Response from developer

멜라토닌이 성찰까지 도와준 계기가 되니 제가 더 감사합니다! 앞으로 더 유익한 앱이 되도록 개발하겠습니다!

의지박약러 수면 치트키

쇼츠 한두 개만 보고 자야지 했다가 매번 새벽 되는 사람이라 깔았는데 이거 진짜 괜찮아요..
전 pro 쓰는데 워치 없어도 수면 점수랑 패턴을 확인할 수 있는 것도 굿. 아침에 점수 알림 오면 은근 갓생 승부욕 생겨요 수면 루틴 치트키 인정입니다

감사합니다:) 수면의 질을 향상시키는 멜라토닌이 되겠습니다!
