10 Best Smart Scales

The Etekcity Apex smart scale is a solid choice for anyone wanting detailed body composition insights beyond just weight. It supports a high weight capacity of up to 400 pounds, making it suitable for most users. The standout feature is its 14 biometric measurements, including body fat, muscle mass, BMI, and heart rate, giving a comprehensive health snapshot that typical scales don’t offer. Its accuracy is good, with precise readings to 0.1 lb or 0.05 kg, which helps track small changes over time.

Connectivity is another strong point—it connects easily via Wi-Fi and syncs with popular health apps like Apple Health, Fitbit, and MyFitnessPal. This makes it great for people who want to keep all their fitness data in one place. The scale also supports unlimited user profiles, so it works well for families or groups. The interactive TFT display shows up to nine metrics directly on the device, so you don’t always need to check your phone.

Design-wise, the Apex has a sleek, modern look with a seamless full-surface platform that’s easy to clean and comfortable to stand on. It’s rechargeable with USB-C, offering up to 90 days of use after just a couple of hours charging, which is very convenient. The arched build adds durability and stability. Some users might find the scale a bit more expensive than basic models, and while it offers many metrics, interpreting all 14 biometric numbers may require some learning. Also, the scale uses bioelectrical impedance analysis, which can be influenced by hydration levels and other factors, so measurements might slightly vary day-to-day. This scale suits health-conscious individuals or families who want detailed body composition tracking with smart features and a stylish, durable design. It’s less ideal if you just want a simple weight reading without extra data.

The RENPHO Smart Scale is a solid choice if you're looking for a smart bathroom scale that goes beyond just measuring weight. It supports weights up to 400 lbs, which covers most users comfortably, and uses 8 electrodes for detailed body composition analysis, including fat, muscle mass, bone mass, and more. This helps you get a fuller picture of your health, not just your weight. The scale pairs with the Renpho Health app, which is easy to use and works with popular health platforms like Apple Health, Google Fit, and Fitbit, so you can track your progress over time and share data with other apps you might already use. It allows unlimited user profiles, making it practical for families. Accuracy is good, with a 0.2 lb margin, but for best results, you need to follow posture instructions carefully.

The scale’s design is sleek and durable, with tempered glass and a retractable handle for easy storage, which is convenient for a bathroom setting. On the downside, it requires 4 AAA batteries, which might be less convenient than rechargeable options, and some users might find the setup or app syncing a bit tricky initially if they're not used to smart devices. Also, the detailed measurements rely on electrical signals, so results can vary depending on hydration and other factors, which is common for this type of technology.

If you want a smart scale that offers thorough body insights with good app support and solid build quality at a reasonable price, the RENPHO model is a strong option. Just be ready to spend a moment learning how to get the most accurate readings.

The WITHINGS Body Comp smart scale is a solid choice for those looking to track more than just their weight. It can handle up to 180 kg (about 400 lbs), which suits most users. What sets it apart is its detailed body composition analysis, measuring 8 key metrics like body water, muscle, bone mass, and even visceral fat. This helps you get a fuller picture of your health, not just a number on the scale. It also offers heart health features such as heart rate tracking and vascular age assessment, which is a unique bonus for monitoring cardiovascular wellness.

The scale connects via both Wi-Fi and Bluetooth, syncing smoothly with its dedicated app and popular health platforms like Apple Health and Google Fit. This makes tracking progress over time easy and accessible on your phone. It supports automatic recognition for up to 8 users, plus special modes for babies, pregnancy, athletes, or those wanting anonymous weigh-ins. Accuracy is strong, with measurements precise to within 0.5%, which is reassuring for consistent tracking. The color screen is bright and clear, showing detailed info right on the device. The design is sleek, lightweight, and portable, weighing just 2.5 kg with a slim profile that fits well in most bathrooms. Battery life is impressive, lasting up to 15 months on included alkaline batteries.

On the downside, the scale is priced higher than basic models, reflecting its advanced features. Some users might find the extensive health data overwhelming or may not need heart and nerve tracking functions. Also, while the app is feature-rich, it requires a smartphone and some tech comfort to fully benefit from all insights. The WITHINGS Body Comp is ideal for health-conscious individuals who want comprehensive body metrics and heart health tracking in one device, especially those who appreciate strong privacy practices and multi-user support. It may be more than necessary for someone just wanting a simple weight scale.
