How Actofit Smart Scale Measures body Composition

Actofit smart scale uses advanced Bioelectric Impedance Analysis (BIA) technology. When you stand on a smart scale a very low, safe electrical signals of high and low frequencies are sent from four transparent glass electrodes through your feet to your legs and abdomen.

Measure body compositionHigh Frequency

Based on the different impedance values the human body is segmented in the different virtual compartment mainly Body Water, Body Fat, Fat Free Mass, Bone etc. On the cellular body-composition level, FFM can be further divided into 3 components: body cell mass (BCM), extracellular fluid (ECF), and extracellular solids (ECS). So the total Fat free mass  is (FFM=BCM+ECF+ECS)

Actofit Smart Scale Parameters and their definitions

1) Body Weight:
Users body weight is measured with high accuracy using four electro-mechanical sensors fitted in the four legs of the machine. The maximum weight that the smart scale can measure is 210Kg.

2) Body Fat Percentage:
The body fat is measured by sending multi frequency current through your body. The body fat percentage (BFP) of a human or other living being is the total mass of fat divided by total body mass, multiplied by 100; body fat includes essential body fat and storage body fat. The body fat percentage is a measure of fitness level.

3) Visceral Fat:
Visceral fat is located deep in the core abdominal area, surrounding and protecting the vital organs. Even if your weight and body fat remains constant, as you get older the distribution of fat changes and is more likely to shift to the abdominal area. Ensuring you have a healthy level of visceral fat directly reduces the risk of certain diseases such as heart disease, high blood pressure and may delay the onset of type 2 diabetes.

4) Muscle Mass:
The predicted weight of muscle in your body. Muscle mass includes the skeletal muscles, smooth muscles, such as cardiac and digestive muscles and the water contained in these muscles. Muscles act as an engine in consuming energy. As your muscle mass increases, the rate at which you burn energy (calories) increases which accelerates your basal metabolic rate (BMR) and helps you reduce excess body fat levels and lose weight in a healthy way.

5) Body Water:
Total Body Water is the total amount of fluid in the body expressed as a percentage of total weight. Body water is an essential part of staying healthy. Over half the body consists of water. It regulates body temperature and helps eliminate waste.

6) Bone Mass:
The predicted weight of bone mineral in your body. While your bone mass is unlikely to undergo noticeable changes in the short term, it’s important to maintain healthy bones by having a balanced diet rich in calcium and by doing plenty of weight-bearing exercises.

7) Physique Rating:
The amount of muscle and body fat levels decides your physique rating. Depending on physique rating human body type can be differentiated in nine body types. As your activity level changes, the balance of body fat and muscle mass will gradually change, which affects your overall physique.

8) Basal Metabolic Rate (BMR):
The daily minimum level of energy or calories your body requires when resting (including sleeping) in order to function effectively. Increasing muscle mass will speed up your basal metabolic rate (BMR). A person with a high BMR burns more calories at rest than a person with a low BMR.

9) Metabolic Age:
Metabolic age is calculated by comparing your basal metabolic rate (BMR) to the BMR average of your chronological age group. If your metabolic age is higher than your actual age, it’s an indication that you need to improve your metabolic rate.

10) Body Mass Index (BMI):
A standardized ratio of weight to height used as a general indicator of health. Your BMI can be calculated by dividing your weight (in kilograms) by the square of your height (in meters).

11) Fat Free Weight:
Fat-free mass, also known as lean body mass, refers to all of your body components except fat. It includes your body’s water, bone, organs, and muscle content.

12) Subcutaneous Fat:
As the name suggests subcutaneous fat is a fat located under the skin. The amount of subcutaneous fat you develop depends on genetics as well as lifestyle factors such as physical activity and diet. Subcutaneous fat is an important part of your body, but if your body is storing too much of it, you may be at a higher risk for health problems

13) Skeletal Muscle %:
A muscle which is connected to the skeleton to form part of the mechanical system which moves the limbs and other parts of the body. Skeletal muscle % is the ratio of your skeletal muscle mass to the total muscle mass multiplied by 100

14) Body Protein %:
Protein is an important component of every cell in the body. Hair and nails are mostly made of protein. Your body uses protein to build and repair tissues. You also use protein to make enzymes, hormones, and other body chemicals. Protein is an important building block of bones, muscles, cartilage, skin, and blood.

15) Health Score:
Your health score is calculated by assessment of all body parameters. The higher health score is an indication of good physical health.

Segmental Fat and Muscle Analysis:

The Segmental fat and muscle analysis provide the amount of muscle mass and fat deposition around different segments of the body. Actofit SmartScale does not do the segmental analysis but its Dual high-frequency BIA technology fulfills the need for segmental analysis by providing more practical parameters like Skeletal Muscle Mass, Visceral Fat, and Subcutaneous fat.

Actofit SmartScale Business App Intent data communication:

The app communication between Actofit and any third party app will happen through Intent data. The intent data will be as follows

Android SmartScale Business app input intent data (From other app to Actofit App)

Android SmartScale Business app output intent data (From Actofit app to other app)

First Time Setup:

Once the intent data is implemented and when user click on the measure button in other app the “Actofit SmartScale Business” page will open from google play store https://play.google.com/store/apps/details?id=com.actofitSmartScale
The “Actofit SmartScale Business” app must be installed from here. Once the app is installed the user has to sign up and then login into the app. This is only one time setup


When a user wants to take measurement from another app then the user will click on the measure button. This will send the intent data to the “Actofit SmartScale ” app from the method explained in the “input intent data” table.
The smart scale will take the data and send that data to “Actofit SmartScale” via bluetooth connection. This data is then made available to other apps through output intent data.

Example Intent App:

You can download the example for Android intent app from here https://drive.google.com/ file/d/ 1U6gzrMAxZN0G1bzR0__ NUwag-jmAe 2-W/view?usp=sharing
This app will send input intent data (Table 1) to Actofit SmartScale Business app and it will receive and display output intent data (Table 2) in the UI
Here is the source code of the app
