Anker Eufy Smart Scale C1 (Body Composition Scale) I am selling this because I purchased a different scale. I have used it for about a year. Batteries, instructions, and the original box are not included. It will be shipped in a different box. 12 Measurable Items: You can measure 12 basic body composition items, such as weight, body fat percentage, BMI, and muscle mass. Bluetooth Connectivity: It supports Bluetooth connection to an app, allowing you to instantly check your measurement data within the app. Data Synchronization with Apps: You can manage your data collectively by syncing with Apple Health, Google Fit, and Fitbit. The dedicated app allows you to view data in graphs and track progress toward your goals. Family Data Registration: Up to 16 people can register their data, so families and groups can manage measurement data without worrying about the number of registered users. *Adding members to the same account will share everyone's measurement data.
