10 Best Body Fat Scales 2025 in the United States

The RENPHO Body Fat Scale is a solid choice for adults wanting detailed insights into their body composition beyond just weight. Its 8-electrode dual-frequency tech provides fairly accurate measurements, with data reportedly close to physician-grade scales. You get a wide range of metrics including BMI, body fat, muscle mass, visceral fat, and segmental body fat percentage, which is useful if you're serious about tracking your health or fitness progress.

The LED display is large and easy to read, showing key stats and a 7-day weight trend right on the scale. Plus, it supports up to 8 user profiles, making it practical for families or groups. The accompanying RENPHO Health App is user-friendly and allows unlimited profiles, syncing smoothly with popular health apps like Apple Health and MyFitnessPal. This makes tracking and sharing your data convenient.

Design-wise, the scale is sturdy, with a large platform that supports up to 400 lbs (180 kg), catering to a wide range of users. The 60-inch cable and durable build add convenience and longevity. Battery life is strong, lasting up to 130 days on 4 AAA batteries included. Like many smart scales, its accuracy can vary slightly depending on hydration and measurement conditions, so it’s best used for trend tracking rather than exact medical readings. The scale’s reliance on a cable might limit placement options compared to fully wireless models. Also, it’s designed mostly for adults and fitness enthusiasts, so those looking for simpler weight-only scales or very high weight capacity might want to consider alternatives. This RENPHO scale offers detailed body composition insights with good accuracy, a user-friendly app, and strong build quality, making it well-suited for users wanting a comprehensive and connected health tracking tool.

Its measurements are known to be quite accurate for home use, especially when paired with the Garmin Connect app, which syncs data via Wi-Fi. This connectivity allows you to track trends over time and manage goals easily on a smartphone.

The high-resolution color LCD screen is sharp and intuitive, showing more info than basic scales. Powered by 4 AAA batteries, it can last up to 9 months, which is convenient and reduces frequent replacements. The design is sleek and modern, with carpet feet to improve stability on soft floors, and it weighs about 4.4 pounds, so it’s easy to move if needed.

The scale requires a Wi-Fi connection and the Garmin Connect app, which may add a small setup step if you’re not comfortable with apps. The Index S2 is a solid choice for those looking for a smart, multi-metric body scale with reliable accuracy, multiple user support, and good app integration, though it might feel a bit technical for users who prefer simple, no-frills devices.

A potential drawback is that it might be more features than necessary for someone just looking to monitor basic weight and BMI.
