온도계날씨 is a free Android application developed by Goldenboard that allows users to check the temperature and weather in all regions of Korea through a map. By utilizing GPS, the app finds the user's location and displays it on a map, providing accurate and up-to-date weather information.

Upon launching the app, users are immediately presented with the temperature and weather conditions of their current location. Alternatively, users can click on the map to view the temperature and weather in different regions of Korea.

It's important to note that in order to ensure smooth service, users need to activate their GPS function. The app only uses location access permissions while it is in use, and does not work in the background. Users are also given the option to allow or reject location information access when using the app for the first time.

With 온도계날씨, users can easily stay informed about the temperature and weather conditions in Korea, making it a useful tool for planning outdoor activities or simply staying prepared for the day ahead.
