はれほす is a laundry app by Shimadzu Business Systems Corporation that helps contribute to the SDGs by making daily laundry environment-friendly, fun, and hassle-free. With this app, users can easily determine whether their laundry can be air-dried outside or not, and when it will be dry. By reducing the use of dryers, users can reduce CO2 emissions and contribute to preventing global warming. Additionally, by reporting the use of dryers, users can earn points that can be used to participate in a lottery to win Amazon gift cards.

The app supports daily laundry activities by providing accurate laundry indices based on various factors such as temperature, humidity, wind, sunshine, and yellow sand. It also predicts the best time to take in the laundry based on precipitation. With over 20 years of experience in weather data analysis, the app provides high-precision predictions of laundry indices and the best time to take in the laundry. Moreover, the app calculates laundry indices for each region in Japan, making it easy for users to get location-specific information. Finally, by reporting the use of dryers, users can share their contribution to reducing CO2 emissions with other users and earn badges.
