This document describes the LEPULSE Smart Body Fat Scale, a personal health assistant designed to track various body composition indicators.

Function Description

The Smart Body Fat Scale utilizes Bio-electrical Impedance Analysis (BIA) technology to provide users with data on important personal health indicators. It measures and displays:

Body Weight: The primary function, displayed in pounds (lb), kilograms (kg), or stones (st).
Body Mass Index (BMI): Calculated based on weight and height, indicating whether a person is underweight, healthy weight, overweight, obese, or severely obese.
Body Fat Rate: The percentage of fat in the body.
Body Water Rate: The percentage of water in the body.
Muscle Mass: The total mass of muscle in the body.
Bone Mass: The total mass of bone in the body.
Protein: An indicator of protein levels.
Heart Rate: Measured during the weighing process.
Basal Metabolic Rate (BMR): The number of calories required to keep the body functioning at rest.

The scale can be used independently to display basic weight and unit information, or it can be paired with the Fitdays App for a comprehensive health tracking experience. When connected to the app, real-time data is synchronized, recorded, and can be viewed in detail, including historical trends and various body data types. The app also allows for personalized settings such as themes, targets, units, measuring sound, language, and password.
