ぜんそくリスク予報 is a free iPhone app developed by the Japan Weather Association. It falls under the Lifestyle category and specifically targets the Health & Fitness subcategory. This app allows users to record and track their asthma condition and overall health by automatically registering weather, temperature, and humidity information from the nearest weather stations.

With this app, users can gain insights into how asthma is affected by weather changes. It is especially helpful for parents with children who have asthma, as they can use the app to check their child's energy level through voice feedback when they are unable to express their condition verbally.

Key features of ぜんそくリスク予報 include clear visual representations of temperature changes over time, timely notifications with points on temperature variations up to 6 hours in advance, a display of asthma risk forecasts up to 10 days ahead, easy-to-understand presentation of daily temperature highs and lows, a chat-style interface to record health conditions and medication information, a simple and user-friendly design suitable for managing children's asthma, and the ability to measure energy levels through voice input.

The app provides various types of information, such as asthma risk forecasts and weather forecasts at the municipal level, asthma risk forecasts, weather forecasts, and temperature forecasts up to 10 days in advance, as well as detailed weather information (weather, temperature, humidity) every hour or every three hours for the past two days.

ぜんそくリスク予報 is a valuable tool for managing asthma and maintaining good health. It not only helps users understand the impact of weather changes on asthma but also facilitates communication and management of children's health conditions.
