About

Noeul ON

Read full description

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. Then, the next day, it tells you whether that forecast held. ■ A sunset app that shows its work After the sun goes down, it asks once: "Compared with the forecast, how was tonight?" Tap one of Better · About right · Not as good, and you're done. Didn't see the sky? Tap "I missed it." Open the app the next day and a result card is waiting — "Yesterday's forecast held · forecast 82, actual 78." The actual figure comes from that day's observations at that spot. When the forecast missed, it names which of the five factors diverged most. ■ 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-colour 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. It also shows how often that threshold will actually fire — "about once a week" — so you aren't guessing where to set it. ■ 673 sunset spots across Korea From the Han River and Gwangalli Beach to Kkotji, Ganwolam, Suncheonman Bay and Jeju's oreum — mapped and described by the terrain they sit on: whether the west is open water or a ridge, and how far and how high that ridge stands. ■ The sky you saw, and that day's score Keep a photo of the sky you watched and it comes back with the next day's result card. That photo stays on your device and is never uploaded. Share one to the gallery only if you want to. Posted photos carry the sunset score of that day. ■ Available in English, 한국어 and 日本語 Weather data by Open-Meteo. Forecasts are estimates based on weather models and may differ from the actual sky.
