From refrigerators to thermostats, every home appliance seems to be getting a smart upgrade these days. And few are as useful for monitoring your health as the smart scale. These devices might look like your standard bathroom scales, but they’re actually far more advanced.
Best smart weights: Take the heavy lifting out of rep counting
From not-so dumb dumbells to adjustable kettlebells, these are the smartest home fitness weights you can buy
Indeed, smart scales aren’t only useful for precise weight measurements. They can also estimate your body fat percentage, BMI, muscle mass, bone density, heart rate, and more. Better yet, they allow you to track all that data right from your smartphone (hence the “smart” part of the name). That way, you can build a health profile to monitor your progress over time.
The team here at Pocket-lint is composed of tech experts, and we know smart gadgets like the back of our hands. Together, we drew from our personal experience and expertise to compile this list of the best smart scales on the market.

Etekcity Smart Scale
Best accuracy
This pick from Etekcity is another fantastic overall option, and its strong suit is accuracy. The secret is in an ITO-coating on the plate that gives the sensors all the surface area they need to measure with precision. The high-quality design is also apparent in the color display. Control it via the VeSync health app to peruse 14 different health metrics. Once all that accurate data is measured, you can sync it with other health apps, too, including both Apple and Android devices.
How do smart scales measure things like BMI and muscle mass?
The technology behind these measurements is simple yet brilliant. A small electrical pulse is sent through your feet, and the scale measures the resistance as it travels through your body. Higher resistance means a higher body fat percentage, while water and muscle generate less resistance. Thus, the scale is able to calculate your body fat composition using little more than a painless electrical pulse.
Similarly, though, you may have to enter some details into the app, you can acalcuate other factors. It’s similar to the way smartwatches calculate things like calories burned. If you provide data like height, age, and sex, you can unlock other measurements as well. The Eufy P2 Pro, for example, offers a whopping 16 different measurements and even has a 3D Virtual Body Mode that lets you explore your body composition.
Are smart scales accurate?
Today’s digital scales are exceptionally accurate in measuring weight. Many have a margin of error in the realm of 1/100th of a pound, so it’s small enough to not even appear on the scale’s display (most smart scale displays only go down to the tenths place). However, the other metrics that smart scales provide are estimates, since they use algorithms based on a variety of data points.
That being said, these estimates are considered “highly accurate.” Every smart scale model and app will have its own degree of precision, and there are a vast number of factors that influence the calculation. To maximize your scale’s accuracy, make sure to enter your data into the app accurately and update it frequently. If you enter your height an inch off, for example, it can throw a monkey wrench into the algorithm.
How accurate is Fitbit’s calorie burn counter?
Ever wonder how accurate your Fitbit calorie burn counter is or even how it compares to Apple Watch’s ability to track calories? Well, it depends.
Thus, the measurements that smart scales provide aren’t accurate enough to please a nutritional scientist, but they’re still sufficiently reliable for monitoring your health with confidence. Consider them reference points in your health journey. The health apps that go along with these smart scales are powerful tools and well-worth adding to your fitness toolkit.
