Wirecutter Smart Scale

A scale can be a bit intimidating, but keeping track of your weight can help you improve your health.1 Whether you’re raising your weight or lowering your weight, or simply looking to keep track of your weight, a smart scale can be a useful tool. 

In addition to measuring weight, bathroom scales now provide information about fat percentage, muscle mass, and more. While all scales include the basics, some offer additional features such as connecting to personal health monitoring apps or measuring your body composition digitally.

Kim Mahony, RD, LDN and Corporate Manager at Lutheran Home Communities, says it is difficult not to get hooked on constantly checking your weight on the scale. The results of your weight can provide insight into your health to some extent, but Mahony recommends paying attention to how you feel, how your clothes fit, your body fat percentage, and your muscle mass as well.

The following are some of the best bathroom scales on the market.

Wirecutter Smart Scale: Buying Guide

Consistency & accuracy

During the weighing process, we weighed over 250 times. Weights and humans were weighed. I would like to briefly clarify the differences between ‘coherence’ and ‘accuracy’ before we proceed. When a scale produces the same result over and over, it will be referred to as consistent. The reading on an accurate scale should be close to what the user actually weighs.

We weighed a subject who was not holding anything to get a sense of the scales. Using dumbbell A and dumbbell B, we weighed them, then weighed them with both dumbbells (49.6 lb), and then weighed them with both dumbbells together (25.8 lb). I’m guessing that the dumbbells are both meant to be 25 lbs, and yes, they’re both from the same company. The dumbbells weren’t weighted properly, so we used professional weights.

Consistency & accuracy of body fat readings

Prior to looking at how we tested body fat, a quick explanation: body fat percentage (BFP) is the total mass divided by the total body mass. BIA is the measurement method used by smart scales. By shooting an electric current through your body and measuring the resistance between the conductors, the smart scale can determine your weight.

The first step to measuring BFP was to establish a standard measurement of BIA. A few accurate methods of determining body fat exist, such as skinfold caliper readings (instrumental body fat pinching) and hydrostatic weighing (underwater). In order to compare the results of the BIA to the skinfold caliper result, we chose it as our standard because it has the highest accuracy-to-repeatability ratio.

For each smart scale, we tested two subjects with similar weight and fat composition on three occasions using the skinfold caliper and three times using the body fat percentage. In order to avoid discrepancies in body fat throughout the day, we conducted the tests within seconds of one another.

Ease of use

Standard and smart scales

We only considered a few factors while analyzing the performance of non-smart bathroom scales because there isn’t much to consider. To switch on the scale, only the most basic scales on the market require you to tap the scale. In contrast to other types of technology, “step-on” technology allowed us to simply walk on everything we studied without having to activate it first.

The clarity of the display was another element we looked at closely. There wasn’t much of a difference between the gadgets on exhibit because they all had similar backlights and display sizes. According to our measurements and comparisons, the area of the iDOO Jumbo – ES09-3089surface M was around 30% larger than the display and scale dimensions of the iDOO Jumbo.

Battery alternatives, non-slip bottoms, and ways to transport the products were all part of our research for this section. We ranked them according to how easy it was to change the batteries and what kind of batteries they utilized. As a result, for those who want to hide their scales while not in use, we graded the process of relocating each bathroom scale from one location to the next.

Smart scales only

For your convenience, we’ve divided them into two groups. We started by looking at how to keep track of your weigh-ins. The two smart scales with smartphone apps (Weight Gurus – 0375 and Yunmai Premium) proved to be the most useful. The app’s overall usefulness was next tested by adding new users, tracking weight, looking at graphs, and connecting to other apps like Apple Health and FitBit.

We also investigated the accuracy of body fat measurements using various scales (because after reading all the other reviews and comments this was the most desired datum from smart scale users). The measures’ precision and accuracy were evaluated.

Important features to look for

Large backlight display: 

Even if a bathroom scale is precise, you won’t be able to use it if the numbers are difficult to read. Thanks to their backlit displays, we were able to easily view the numbers on all scales tested.

Design:

The design of a product shouldn’t be the only factor you consider when shopping, but the more it looks and feels good, the more likely you are to use it. Dimensions and weight are also important attributes to consider when shopping.

Weight tracking (smart scales only): 

Having the ability to see the changes in your weight over time is wonderful because it takes away all the effort that would otherwise be required. By using the phone apps, you can quickly and easily visualize trends with graphs and other visuals. Even programs such as FitBit and Google Fit can be integrated with the Weight Gurus – 0375.

Batteries:

There are some scales that use Lithium CR2032, which is a flat, disc-like battery designed for use in digital scales. You can see the performance differences in the graphs from Energizer. It appears that AAAs last longer and are more reliable.

Standard vs. smart scales

Standard scale:

In the realm of digital bathroom scales, your typical old-fashioned non-smart model can measure only one thing: weight. These scales often measure weight in pounds, kilograms, or stones.

It may seem strange that there are no spring-loaded mechanical scales included. There is a simple reason for this: mechanical scales are relatively expensive and perform about as well as smarter alternatives, but give you only the standard function.

Smart scales:

In addition to measuring weight, they also offer numerous other features. Among these are body fat, body mass index, muscle percentage, water percentage, bone mass, body mass ratio, and protein percentage.

Final Verdict 

A bathroom scale is an essential tool for all of you who exercise, lose weight and track your health. Weight Gurus – 0375 is the most functional and informative smart scale on the market since it integrates with most health apps and Smartwatch programs. It was 99.83% accurate on just under 3,000 pounds and was integrated with just about any health app. In addition, the readings of body fat were consistently low, suggesting that it can definitely be used to track your body composition.

As well as the smart Yunmai Premium Smart Scale, there was also the standard Etekcity Glass EB4074C that performed well. With the former, you get an incredible smart scale that is very accurate down to the tenth of a pound, and with the latter, you get an ordinary scale that is perfectly accurate and consistent.
