マルチグリルアプリ is a free lifestyle application developed by HARMAN CO. LTD. It is designed for specific models in the プログレ, ピアット, and スマートコンロ series. The app offers various features, including a recipe search function tailored to the gas cooker's capabilities, real-time display of cooker status (cooking, auto-cooking end, errors), and instructional videos for changing the cooker's batteries.

The app allows users to search for recipes, send cooking modes to the cooker from their smartphones, and receive notifications for auto-cooking completion or errors. Note that features ② and ③ are exclusive to the プログレ series. Keep in mind that the app does not support tablets and may not be accessible based on your smartphone and network environment.
