바디키 is a health habit formation app designed for Android users, developed by amwaykorea. It offers two primary modes: the Program Mode, which includes the BodyKey MyFit program for fat loss and the BodyKey M program for muscle gain, and the Always-On Mode, which helps users maintain healthy habits independently. Users can engage in a variety of daily habit missions that accumulate points, known as KEY, which can be redeemed for Amway products after program completion.

The app provides personalized body composition analysis through big data, allowing users to set and manage fitness goals. Key features include daily habit tracking for steps, water intake, diet logging, and home training tailored to specific objectives, along with expert tips. Additionally, users can manage their InBody analysis results, participate in special missions for bonus points, and share their activities with others, making it a comprehensive tool for health and fitness enthusiasts.
