The best smart scale for weight and body fat [2025]

A smart scale is an advanced digital weighing device that not only measures weight but also tracks body composition metrics like body fat percentage, muscle mass, bone density, and water weight. The best smart scales, such as the Withings Body+ and the Garmin Index S2, use bioelectrical impedance analysis (BIA) to send a low electrical current through the body to estimate fat and muscle distribution. These scales sync with smartphone apps via Bluetooth or Wi-Fi, allowing users to track trends, set fitness goals, and integrate with health platforms like Apple Health, Google Fit, or Fitbit for a more comprehensive health overview.

Smart scales are essential for individuals looking to monitor their health beyond just weight, providing deeper insights into body composition changes over time. They help users set realistic fitness goals, track muscle gain or fat loss progress, and even detect potential health risks linked to high body fat percentages. For athletes and fitness enthusiasts, smart scales provide valuable data to fine-tune training and nutrition plans. Meanwhile, for those on a weight management journey, they offer motivation and accountability by visualizing progress through connected health apps.
