출퇴근 이동 시간을 2시간까지 고르실 수 있습니다. 그동안 100분에서 막혀 있었습니다. 그보다 오래 걸리시는 분들이 계시다는 의견을 주셔서 늘렸습니다. 2시간이 넘으면 5분 단위로 직접 정하실 수 있습니다. 적중률 채점 방식을 고쳤습니다. 예보는 "10시에 비"처럼 한 시간 전체에 대한 말인데, 채점은 그 시간에 처음 받은 실황 하나로 판정했습니다. 10시 40분부터 비가 왔는데 10시 5분에 확인했다면, 맞은 예보가 틀린 것으로 기록됐습니다. 이제 그 시간 안에 한 번이라도 비를 보면 비가 온 시간으로 봅니다. 「비 올 때만 따로 보면」의 숫자가 이전보다 올라갈 수 있습니다. 그동안 실제보다 낮게 보여 드렸기 때문입니다.
We'll let you know when the rain starts and stops. Precipitation alerts based on the KMA's ultra-short-term forecast.
This is a weather app that tells you when it will rain, not whether it will rain. Based on the Korea Meteorological Administration's ultra-short-term forecast, it tells you when rain or snow will start and when it will stop. Instead of listing temperature and weather icons, it answers only one question: "Is it safe to go out now?" When you turn on the screen, the answer is first displayed as whether your umbrella is open or closed, and below that, the time interval for when it will start is displayed. ■ We notify you before you leave If rain or snow is forecast to start at a registered location, we send you a notification before you depart. If you turn on the morning briefing, we summarize in a single line whether you need an umbrella today, timed to your departure time. ■ Check both your home and work If you set your commute route, it checks and compares your starting and ending points separately. You cannot tell if a situation like "It's not raining in front of my house, but it is raining near my office" by looking at only one location. ■ Not just rain, but snow and wind as well If it snows, we advise you to leave early, taking into account slippery conditions and potential delays. We even inform you that your umbrella may turn inside out on windy days. ■ You don't need to open the app The precipitation timeline is displayed on the home screen widget, and you can check the remaining time in the notification area while it is raining. ■ We don't hide whether our predictions are accurate Forecasts can be wrong. Usagak records the forecasts we send, compares them with the actual conditions at the same time to calculate the accuracy rate, and displays the results exactly as they are. ■ What Usagak does not do · We do not continuously track your location. We only view fixed locations that you have registered yourself. · We do not create our own forecasts. We simply deliver the ultra-short-term forecasts and actual conditions released by the Korea Meteorological Administration without processing and organize them for easy viewing. · We do not set a fixed start time. Since KMA forecasts are in one-hour increments, we do not specify "in 30 minutes" but provide guidance in intervals. · We do not ask you to create an account. There is no login or server. Forecast Source: Korea Meteorological Administration Ultra-short-term Forecast · Ultra-short-term Real-time (Public Data Portal) Weather advisories are issued only by the Korea Meteorological Administration.
