FAQs

What Are Electrodes, and What Is the Difference Between a 4-Electrode and 8-Electrode Scale?

Electrodes are contact points that send and receive low-level electrical signals to measure body composition. They allow a smart scale to collect body composition data and estimate metrics such as body fat and muscle mass.

A 4-electrode scale typically uses foot electrodes to measure through the lower body, while an 8-electrode scale uses both hand and foot electrodes. By measuring from more contact points, an 8-electrode scale can provide segmental body composition analysis for the arms, legs, and torso, offering a more comprehensive view of your body composition.

Why does this body composition scale have a handle?

The handle provides additional hand electrodes that work together with the foot electrodes to collect more body composition data. This 8-electrode design enables more detailed segmental analysis of your arms, legs, and torso for a more complete view of fat and muscle distribution.

What are the benefits of the built-in stand design?

The adjustable stand keeps the handle and display at a comfortable height, reducing the need to bend down during measurement. It makes the entire process easier, more comfortable, and more accessible for everyday use.

Do I need to check my phone after every measurement?

No. The BS1 features a built-in display that lets you view your essential measurement results directly on the scale, so you don’t need to reach for your phone after every measurement.

For a more detailed view, you can connect the scale to the FED Fitness App to review 50+ body composition metrics, track changes over time, and access detailed reports. Use the display for quick everyday check-ins and the app when you want a deeper look at your data.

Do I need to pay to use the FED Fitness App?

No. The FED Fitness App is completely free to use, with no additional fees required to access its core features. You can use the app to track your body composition and monitor changes over time.

How can I get more consistent body composition measurements?

Body composition measurements can vary due to factors such as hydration, exercise, food intake, and time of day. To improve consistency, measure under similar conditions each time and make sure your hands and feet have proper contact with the electrodes.

For more meaningful results, focus on long-term trends rather than a single reading. Consistent measurement conditions can make it easier to track changes in your body composition over time.
