## What is Noeul ON?

Will tonight's sunset be worth it?

Noeul ON reads cloud cover, humidity, air quality and the western sky path to score tonight's sunset from 0 to 100 — and pings you an hour before golden hour when it looks good.

■ A sunset score with reasons
See the score and its grade at a glance (Legendary to Low odds).
Five factors — cloud canvas, cloud type, humidity, air clarity and the light path — explain exactly why tonight scored what it did.

■ Never miss the timing
A live timeline shows golden hour, sunset, and the peak-color window, with a countdown to the moment the sky turns.

■ An alert when it's time to go out
On days that clear your own threshold, you get a notification one hour before golden hour.

■ 673 sunset spots across Korea
From the Han River and Gwangalli Beach to Kkotji, Ganwolam, Suncheonman Bay and Jeju's oreum — mapped, with photos taken at each spot.
Each one is described by the terrain it sits on: whether the west is open water or a ridge, and how far and high that ridge stands.

■ A community of sunset photos
Post what you shot, like what others caught. Every photo records the sunset score of that day.
Browse this week's best, or filter for "Legendary" skies that scored 85+.

■ Available in English, 한국어 and 日本語

## Version history (last 5 releases)

### 1.10 — 2026-09-15

■ See when the color actually ends
The peak window now shows its start and end time, so you know whether to pack up or stick around.

■ Know how often an alert will fire before you set it
Move the threshold and we tell you what to expect, such as about once a week.

■ More accurate sunset and golden hour times
We replaced the solar position algorithm with a high precision one and halved the error.

### 1.9 — 2026-09-13

대부분 눈에 안 보이는 수정입니다.

• 오프라인일 때 대체 데이터로 알림이 울리던 것을 막았습니다. 예보를 못 받으면 기존 예약을 그대로 둡니다.
• 좌표가 틀려 엉뚱한 지역을 가리키던 명소 5곳을 고쳤습니다.
• 지도가 늘 전국 화면이 아니라 보고 있는 지점에서 열립니다.
• 일본어 화면의 글꼴이 하나로 통일됐습니다.
• 기기 시간대에 따라 노을 절정 시각이 달라지던 문제를 고쳤습니다.

### 1.8 — 2026-09-13

Spot names and descriptions near Seoul, Busan, Jeju, Gangneung, Chuncheon, Incheon, Gyeongju and Yeosu are now in English — 116 more places.

The App Store page and iPad screenshots have been tidied up too.

### 1.7 — 2026-09-10

아이패드에서도 쓸 수 있습니다. 넓은 화면에 맞게 지도와 목록을 다시 짰고, 가로로 돌려도 그대로 보입니다.

### 1.6 — 2026-09-08

App Store에 보이는 소개 이미지를 다듬었습니다. 앱이 무엇을 하는지 한눈에 들어오도록 설명을 얹었어요.
