Why we picked it

The Oxiline Scale X Pro is a complete smart scale providing 8 live readings on the display and 16 total readings when connected to the app. Body measurements include BMI, fat %, visceral fat, water weight, and more. During testing, patients reported that having most measurements on the scale display made it very convenient, especially because it displays results in under 10 seconds. The app lacks some of the insights and suggestions other devices on the list offer, however, it does connect with Apple/Android health and older users reported that it was simple and easy to use. It is also worth mentioning that Oxiline is the only company we reviewed that offers a lifetime warranty on all its products.

Accuracy Report

The real reason it made number 1 on our list is because of its reliable results. The Scale X Pro was the most accurate and precise scale we tested. Patient results had a +/- 3% deviation compared to the DEXA control results. Weight had a lower 0.5% deviation. This scale could be considered professional grade and could be used by nutritionists and weight-loss clinics. Patients did not report any issues with app connectivity and actually had positive feedback regarding their overall user experience.

Why we picked it

The Withings Body Comp is a versatile smart scale that measures weight, body fat & water percentage, muscle & bone mass, and visceral fat. It has a beautiful design and is paired with a feature-packed app that provides insights and other valuable information. However, older users may have a hard time navigating the app due to its complex options. This digital scale’s minimalist design offers a display that looks good in your bathroom but may be too simple for its $209.85 price tag. Even though the data is clearly visible, a dot LCD display is outdated considering other options in this list.

Accuracy Report

Even though Withings claims to address the accuracy issue with new technology, this scale uses BIA technology like all the other scales on this list. The patient test results were consistent but somewhat inaccurate with a +/- deviation of 8% for all measurements except weight where the deviation was under 0.5% This deviation is not ideal, however, it is acceptable for a non-professional scale. It would give you a close approximation of your body data. 

Product Specs

Total number of readings: 6

Battery life: up to 10 months (uses 4 AAA batteries)

Minimum weight: 9 lbs

Max weight: 440 lbs

Display size: 2.4 inches

Why we picked it

The FitTrack Dara 2.0 is a complete smart bathroom scale that offers 17 unique body measurements and is paired with an app that provides data as well as a paid option for fitness and nutrition suggestions. The scale uses a simple digital display that only shows weight, while all the other measurements can only be seen on the app. Even though the fitness and nutritional plan is a paid option, we do think it’s a valuable addition for those that want it.

Accuracy Report

This scale promises 17 unique measurements and it almost delivers, unfortunately, it has issues with fat-related data. It delivered a +/- 5% deviation in all patient readings except the 6 readings relating to fat in which it scored a +/- 12% deviation compared to the DEXA control results. It’s unfortunate that the Dara has issues with arguably the most sought-after measurement, therefore this scale is not considered fully reliable.

Product Specs

Total number of readings: 17
Battery life: up to 1 year (uses 4 AAA batteries)
Minimum weight: 5 lbs
Max weight: 397 lbs
Display size: About 2 inches (uses mobile app for display)

Customer Reviews ★★★★ 36

Why we picked it

The Etekcity smart scale is an interesting option that offers a range of features to help you track your health. It measures 14 body metrics and can recognize up to 12 users. It offers a great display that shows the different measurements on well-designed screens. However, it does take about 45-60 seconds to fully display all the data. Bluetooth connectivity and integration with the VeSync app make it easy to track your progress over time. Our patients did have issues connecting with the app and after some quick research, many users have reported the same issue. There were instances where the scale would work fine while other times in which it quickly disconnected.

Accuracy Report

The Etekcity smart scale provided inconsistent results but with an acceptable average deviation of +/- 7% What this means is that sometimes it displays wild readings. For instance, patient testing BMI results were 22, 22.5, 32, 23, and 25. This means that it needed a couple of tries to get an understanding of what are an actual estimate and a wild reading. These are acceptable results for a non-professional device, however, the slow result time and the connectivity issues make it frustrating to use on a daily basis. If Etekcity can address these issues this scale would move up on the list.

Why we picked it

The Garmin Index S2 is a high-end smart scale that integrates with other Garmin devices for a more comprehensive view of your health data. In addition to measuring weight, body fat percentage, BMI, muscle mass, bone mass, and body water percentage, it also offers Wi-Fi connectivity and can recognize up to 16 users. You can view 6 body measurements on the scale digital display, however at 2” it is quite small and uses an outdated interface that does not offer high contrast. Therefore to view all data it is almost necessary to utilize the app every time.

Accuracy Report

During our patient testing the Index S2 averaged a +/-10% deviation. Considering the importance of Garmin in the field of fitness these results were surprising and disappointing. Patients reported that they had no issues connecting the scale with the app but that even after sequential tests the results were always different making it difficult to know what was right and wrong. Sorry to disappoint Garmin fans, but this scale barely made the cut into our top 5.

Evaluation Process

A recent study conducted by a team of experts aimed to pick the top 10 smart scales available in the market. The study involved several stages of evaluation, including the use of a DEXA (Dual-Energy X-Ray Absorptiometry) machine to compare accuracy, as well as a patient review panel to evaluate ease of use and other factors.

The DEXA machine is a state-of-the-art medical device that uses low-dose X-rays to measure the body composition, including bone density, muscle mass, and fat percentage. The machine works by passing two different energy X-rays through the body and measuring the amount of each energy absorbed by different tissues. This information is then used to calculate the body composition, providing a highly accurate and reliable measurement.

In the study, a group of patients was given a set of smart scales to use for a period of time. They were asked to evaluate the ease of use, design, and overall functionality of the scales, as well as any other relevant factors such as connectivity and app integration. The results of the patient review were combined with the accuracy measurements obtained from the DEXA machine to create a comprehensive evaluation of each smart scale.

FAQ

Q: What is Dual-Energy X-ray Absorptiometry (DEXA)

Dual-Energy X-ray Absorptiometry (DEXA or DXA) is a non-invasive imaging technique used to measure body composition. It is considered one of the most accurate and reliable methods for assessing fat mass, lean mass, and bone mineral density.

DEXA works by passing two different low-dose X-ray energy beams through the body. As the X-rays pass through the body, they are absorbed by tissues at different rates, depending on the composition of the tissues. Bone, fat, and lean tissue each have unique absorption characteristics, which allows DEXA to differentiate and quantify them.

Q: What is a smart scale and how is it different from a digital scale?

A smart scale is a type of digital scale that is equipped with advanced features to measure various metrics such as weight, body fat percentage, muscle mass, bone density, and hydration levels. Additionally, a smart scale allows for device connectivity via Bluetooth or Wifi so that users can view, organize, and export their data.

Q: How does a smart scale work?

Smart scales use sensors to detect small electrical currents to measure various metrics. When a user steps on a smart scale, the sensors in the scale send a small electrical current through the user’s body. This current passes through the body’s tissues, and the sensors detect the resistance to the current, which is used to calculate the metrics being measured.

Q: Are smart scales accurate?

Smart scales can provide accurate measurements, but the accuracy may vary depending on the specific scale and the method used to measure the metrics. DocReview experts recommend testing the accuracy of each scale’s readings against the most accurate method available for each metric, such as BIA for body composition measurements.

Q: Can smart scales connect to other devices?

Yes, most smart scales can connect to other devices such as smartphones, fitness trackers, and smartwatches through Bluetooth or Wi-Fi. This allows users to track their progress over time and receive personalized insights and recommendations based on their data.

Q: What additional features do smart scales offer?

In addition to measuring weight, body fat percentage, muscle mass, bone density, and hydration levels, many smart scales offer additional features such as pregnancy mode, local weather information, and the ability to track multiple users.

Q: How does a smart scale measure BMI?

Smart scales use a technique called bioelectrical impedance analysis (BIA) to measure body composition, including BMI.BIA works by sending a small electrical current through the body and measuring the resistance of the current as it travels through different types of tissue, such as muscle, fat, and bone. Because muscle and other lean tissue have higher water content and conduct electricity better than fat tissue, the resistance of the current can be used to estimate the amount of body fat.

Once the weight scale has measured your weight and body fat percentage through BIA, it can calculate your BMI by dividing your weight in kilograms by the square of your height in meters.

Q: Are smart scales worth the cost?

Smart scales can be a valuable tool for people looking to monitor their health and fitness goals. The cost of a smart scale may depend on the specific features offered and the user’s budget. DocReview experts recommend considering factors such as accuracy, connectivity, user-friendliness, additional features, and value for money when choosing a smart scale.

Q: Can smart scales be used by multiple users?

Yes, most smart scales can be used by multiple users and can track each user’s progress separately. Some smart scales even allow for guest mode, which allows visitors to use the scale without their data being stored.
