Weather: Yesterday vs Today

Is it colder than yesterday? Find out at a glance. Haneul shows today's weather side by side with yesterday's. Instead of just a number, it tells you in one sentence how much warmer or cooler today is. [Yesterday · Today · Tomorrow] • "2.3°C warmer than yesterday" — the average temperature difference, compared hour by hour. • See whether tomorrow will be warmer or cooler than today. • Yesterday, today and tomorrow temperature lines on one chart. • Compare highs and lows, average humidity, chance of rain, and temperatures at key hours (00:00, 06:00, 12:00, 18:00). [What to wear] • Outfit suggestions for today and tomorrow, from short sleeves to a heavy coat. [Before you head out] • Outdoor walk guide: is today good for a walk? Based on rain, air quality and temperature. • What-to-bring checklist: an umbrella if rain is likely in the next 12 hours, a mask when air quality is poor, and a light jacket when the day-night temperature gap is large. [Today's weather] • Current temperature, feels-like, humidity, wind, air quality (fine dust) and UV index • Swipeable hourly temperature chart across several days, plus hourly forecast (temperature, humidity, chance of rain) • 14-day daily forecast (high/low, chance of rain, max wind). Tap a day to see its hourly forecast. • Your last downloaded weather stays visible when you're offline. [6 home-screen widgets] • Current weather (2×2), mini temperature (1×1), hourly (4×2), slim hourly (4×1), daily (4×1), 6-hour interval (4×2) • Choose widget background (none, dark, light) and text size (small, medium, large) in Settings. [Status-bar weather] • Optionally pin the current temperature and conditions to your status bar, with the temperature shown as the status-bar icon. • Update every 15 min, 30 min, 1, 3, 6, 12 or 24 hours. [Rain alert] • Turn it on to get a heads-up when the hourly forecast for the city you are viewing shows rain or snow (60% chance or more) within 3 hours. • At most once every 6 hours, and never between 10 PM and 7 AM. • This is a forecast-based notice, not an official weather warning. [Location & city search] • Weather for your current location. No location permission? Just search for a city. • Search cities worldwide, including in Korean. • Tap ☆ to keep up to 20 favorite cities and switch to them right from the search screen. • Widgets and the status-bar notification never use background location — they show the place you last viewed in the app. [Settings] • °C / °F, app language (system default, English, Korean), dark mode (system default, light, dark) [Data sources] • Weather forecast · city search: Open-Meteo (https://open-meteo.com) • UV index · fine dust (PM10/PM2.5): Open-Meteo Air Quality API (https://open-meteo.com/en/docs/air-quality-api) • City search (Korean and other scripts): OpenStreetMap · Nominatim (https://www.openstreetmap.org/copyright) Weather data by Open-Meteo.com (CC BY 4.0) / © OpenStreetMap contributors (ODbL) Forecasts are for reference and may differ from actual conditions.
