10 Best Body Fat Scales 2025 in the United States

The RENPHO Bluetooth Body Fat Scale is a solid choice for those wanting more than just weight tracking. It measures 13 body metrics, including body fat, BMI, muscle, and bone mass, which gives a fuller picture of your health. The scale connects via Bluetooth to the Renpho Health App, which syncs with popular fitness platforms like Samsung Health and Apple Health, though it currently doesn't support iPhone 17 series devices. It supports profiles for up to 20 users, making it ideal for families or couples who want to track their progress separately.

The scale has a clear LED display with backlighting for easy reading, and it automatically calibrates to ensure accurate results. Its weight capacity of 396 lbs fits most users, and the tempered glass design with four sensors feels sturdy and looks modern. Setup is straightforward through the app and requires a flat, hard surface for best accuracy.

While the scale offers many useful measurements, those requiring medical-grade precision might want to consider more advanced devices. It depends on the smartphone app for syncing detailed data, so if you’re not comfortable with apps or don’t have a compatible phone, some features might be less useful. Additionally, it uses AAA batteries that will need occasional replacement. This RENPHO scale is an affordable, easy-to-use tool that tracks multiple body health metrics and supports multiple users, with valuable app integration despite some minor compatibility and battery maintenance considerations.

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.

The Runstar Smart Scale is designed for those interested in tracking their body composition with precision. One of its standout features is the ability to measure 28 different metrics, including body fat, muscle mass, and BMI. This is particularly beneficial for fitness enthusiasts who want an in-depth analysis of their health and progress. With its intuitive Starfit APP, users can easily track measurements over time, which is a great way to stay motivated on fitness journeys.

The full-color TFT LCD display is another plus, making it easy to read results immediately after weighing yourself. The scale's ability to accommodate unlimited user profiles also makes it an excellent choice for families or shared living situations, as up to 24 profiles can be managed through a single app.

There are a few drawbacks to consider. The scale requires Bluetooth pairing with the Starfit APP before use, which may be a hurdle for less tech-savvy consumers. Also, while the measurement accuracy is generally good, it's worth noting that the athlete mode may be necessary for those with a fitness background to get the most accurate data. The design is robust but somewhat bulky, which might be a concern for those with limited bathroom space.
