Do I need to download mobile app to use my scale?

Yes, if you want to measure full body compositions and take advantage of the smart functions.

Without the Arboleaf mobile app you can only measure body weight just like a regular digital weight scale.

You need the mobile app to access your body composition information, such as body fat, body water, muscle mass, etc., to track your weight and body fat and other body composition data. In other words, the scale and the mobile app together make a complete smart body composition scale.
