The app "電動マッサージ機" serves as a handheld massager designed to alleviate everyday fatigue and promote relaxation. It is available for iPhone users and is licensed for free, making it accessible to a broad audience. The application is straightforward to use; users simply open the app and press the "Start" button to begin their massage experience.

However, there are important usage guidelines and precautions to consider. Individuals with certain medical conditions, such as malignant tumors, heart diseases, or those with medical devices like pacemakers, should avoid using the massager. Additionally, the app is intended solely for massage purposes, and prolonged use may cause the device to overheat, so users should monitor the temperature during operation.
