쌓기만 하세요. 챙기는 건 더닝이 합니다. 할 일이 떠오를 때마다 앱을 열고, 어디에 넣을지 고르고, 제목을 붙이고, 날짜를 정하고… 그 과정이 번거로워서 결국 안 적게 됩니다. 더닝은 그냥 적기만 하면 됩니다. ■ 적는 순간 끝 생각나는 대로 한 줄 적고 저장하세요. 사진이나 서류를 붙여도 됩니다. 저장은 언제나 먼저 끝나고, 정리는 뒤에서 이어집니다. ■ 제목도, 할 일도, 기한도 대신 뽑아줍니다 "다음 주 수요일까지 관리비 이체하기"라고만 적으면 제목과 해야 할 일, 기한까지 정리됩니다. 사진 속 글자도 읽습니다. ■ 잊을 만하면 챙겨줍니다 기한이 다가오면 알려주고, 오래 손대지 않은 메모도 조용히 다시 꺼내줍니다. 재촉이 아니라 안부에 가깝게. ■ 캘린더에도 올려둡니다 확인한 기한은 iOS 캘린더 일정이 됩니다. 원하지 않으면 설정에서 끄면 됩니다. ■ 로그인 없이, 이 아이폰 안에서 회원가입도 로그인도 없습니다. 메모는 기기에 저장되고, 정리를 위해 보내는 순간 외에는 밖으로 나가지 않습니다. 그마저도 설정에서 끌 수 있습니다. ■ 챙김 기준은 직접 정합니다 기한을 며칠 전부터 챙길지, 조용한 메모를 며칠 만에 꺼낼지, 알림을 몇 시에 받을지 모두 조절할 수 있습니다. 알림 전체를 끄는 것도 됩니다. 정리 결과는 자동 추정이라 틀릴 수 있습니다. 중요한 일정은 직접 확인해 주세요. 이용약관: https://dunning-note-proxy.tukkboy.workers.dev/terms 개인정보처리방침: https://dunning-note-proxy.tukkboy.workers.dev/privacy 더닝 플러스는 월 2,900원 자동 갱신 구독입니다. 첫 1개월은 무료이며, 구독은 만료 24시간 전까지 해지하지 않으면 자동으로 갱신됩니다. 해지는 iPhone 설정 > Apple 계정 > 구독에서 언제든 할 수 있습니다.
