The Corona Comfortable Home App is a lifestyle application developed by 株式会社コロナ. This free app allows users to operate their water heater, air conditioner, and hot water in the bath from the comfort of their own home or on the go. With the app, users can not only control these devices but also monitor their usage status and receive alerts about room temperature changes.

One of the main functions of the app is its ability to control air conditioners. Users can start or stop the air conditioner, adjust the set temperature, and set timers for one week at a time, all from their smartphone. The app also sends notifications to the user's device when the temperature goes above or below the specified room temperature. Additionally, users can check the usage status of their family's air conditioners, even when they are away.

Another key feature of the app is its compatibility with Eco Cute, Corona Corporation's home heat pump water heater. Users can use hot water from their bath at home or remotely, check the usage status and available amount of hot water from their home water heater, and even monitor the state of their family in the bathroom from another room. Similar to the air conditioner function, users can also check the usage status of hot water for their family members who live apart.

The Corona Comfortable Home App requires Android 9 or later and a wireless LAN environment. However, it is not compatible with tablet devices and the availability of certain functions may vary depending on the smartphone settings and communication environment. Overall, this app provides convenient control and monitoring capabilities for managing the comfort of your home, no matter where you are.
