Thanks to a wide range of measured data points, an intuitive app experience and impressive battery life, this latest smart scale from Qardio lands highly in our rankings. The amount of data mined from one reading is impeccable, covering everything from body mass index and muscle mass to basal metabolic rate, skeletal muscle, metabolic age and more. We also appreciated the dual connectivity that allows you to utilize WiFi or Bluetooth to connect the scale to the free Qardio app for data tracking.

The QardioBase X is also capable of recognizing up to eight athletes with individualized reports, but having those readouts go to the appropriate account can take some extra legwork. Some athletes have noted that multiple users can create traffic jams during data syncs, causing users to receive inaccurate or mislabeled information. For single-user households, though, these problems should never come to fruition.

With multiple electrical frequencies providing a more precise and accurate BIA readout, this smart scale from Withings is a definite cut above the rest. While the Body Comp gives estimates on the typical muscle and bone mass of each athlete, this profile also measures visceral fat, which is typically only achievable through more advanced practices like CT scans or MRIs. We also appreciate that if you are have trouble syncing your measurements to the companion app or other service, the Body Comp can store up to 16 readings until a proper wireless syncing connection can be established.

There are some pitfalls to be had with this impressive smart scale, however, including an app interface that can be quite the bear to navigate at times. Some have noted that finding key settings like “pregnancy mode” and other toggles can take some time without clear instruction, leading to a little more setup period than desired.

The C1 from Eufy is a great option for both beginners as well as athletes on a budget. Even despite the $30 price tag, this impressive smart scale can track up to 12 metrics for up to 16 athletes, which is quite the feat for a device carrying less cost than all other smart scales in this roundup. Plus, setup across the companion app is simple and intuitive, provided you have a reliable Bluetooth connection.

Of course, though, this premium profile can’t be all positives, and you can begin to see that in the smaller footprint of this sleek silhouette. There’s less surface area than other scales, meaning finding the right foot placement can be difficult for those with wider stances. Still, for less than $40, we’re happy to readjust our standing posture to unlock a better understanding of our body composition.

The Garmin Index S2 was a quick standout in testing thanks to its intuitive setup and easy-to-decipher metrics after each weigh-in. Having experience with the Garmin Connect app also allowed for a more streamlined readout, combining our measured data with other statistics gathered through our other devices, including the all-new Garmin Forerunner 265 running watch. This one stop shop approach created a great platform for data digestion, showcasing all applicable metrics in a legible, understandable fashion.

We will note, however, that our experiences with the Index S2 smart scale were heavily influenced by our past knowledge of the Connect app from Garmin. We knew where the metrics would be logged, allowing us to quickly locate them for post-weigh-in analysis. This could be more of a challenging endeavor, though, for athletes not privy to the Garmin landscape.

To garner more accurate measurements, you’ll need more electrodes, but the surface area of a smart scale only allows for so many in one contained area. Well, to provide a more precise full-body analysis, this impressive silhouette from Sportneer incorporates a cabled handle attachment, bringing four more electrodes to the mix for more accurate body composition measurements. We appreciate this convenient note, as a cabled handle is not at all inconvenient to hold through a quick smart scale session.

All the logged data is able to be viewed through Sportneer’s companion app, but sadly, there’s limited compatibility across other, more popular platforms. We would have appreciated a MyFitnessPal integration, for example, as this remains one of the best apps for tracking daily nutrition and meals. For its enhanced electrode performance and affordable price, however, we felt it worthy of inclusion.

In terms of in-app experience, this Elis 1 smart scale from Renpho is one to admire. Each measured unit is easy to read and differentiate, making it much more approachable to monitor progress and results. Additionally, the Renpho Elis 1 is compatible with major health and wellness platforms for a more streamlined, convenient experience, including Apple Health, Google Fit and Samsung Health. This allowed us to keep all our metrics in one convenient place without much hassle.

Despite the legible data and multiple platform compatibility, though, we did experience some lag when it came to the Bluetooth connection between the scale itself and our smartphone. This caused a slight delay on numerous occasions, leading to repeated weigh-ins. While this isn’t the most egregious negative — weighing in only takes a few seconds, after all — it is worth noting, especially when compared to other smart scales that showcased zero connectivity issues.

When it comes to digital fitness tools, it helps to keep the devices under the same platform. For Fitbit users, this Aria Air smart scale can be the perfect accessory to your go-to fitness tracker thanks to a simple setup procedure, sleek aesthetics and easy to follow instructions. While we were disappointed in the number of metrics tracked through this profile, we think of this smart scale as more of an extension to the wrist-worn Fitbit profile, allowing for more precise readings when it comes to weight while the wrist sensors take care of other data points.

Additionally, the Aria Air can be utilized by an unlimited amount of users, allowing everyone in the household to take advantage of the easy-to-read display and accurate sensors. Would we recommend this as a must-have for all Fitbit enthusiasts? No, but if you are curious about BMI and where your training could be best suited to affect your weight, it’s a worthwhile addition to your training get-up.

What good is a smart scale if you can’t read the data results? Well, thanks to a large thin-film-transistor (TFT) display, this HR Smart Fitness Scale from Etekcity allows for easier legibility from multiple angles, creating a more approachable, enjoyable weigh-in experience for all. We also admired the simple setup process and near-seamless compatibility with multiple fitness platforms including Fitbit, MyFitnessPal, Apple Health and more.

The Etekcity HR also measures a bevy of data points — 14 in total. While we admit that this may be overkill for most athletes, we do like how the scale’s display module can be customized to fit your personal needs. There’s no need to sit through a scrolling metric readout if you only care about two or three metrics, right?

We like this Xiaomi Mi scale for its sleek presentation and simple display. This smart scale doesn’t run you through a ticker tape of readouts, but rather just lets you view your weight total and leaves other metrics for the in-app experience. While the 330-pound max weight is lighter than other scales in this roundup, we feel this capacity should still suit most athletes looking to take advantage of the 13 available metrics.

Of course, that simple on-scale reading could be viewed through multiple lenses, depending on what you’re looking to get out of your fitness gear. If you’re okay with just viewing the essential statistics upfront and diving further into detail on the app, then this is a solid option for you. However, if you want a full readout after each weigh-in, you’ll either want to keep your phone handy or opt for a more interactive smart scale.

Naturally, a scale can serve more than one purpose in the confines of your home or apartment. Perhaps you want to monitor your child’s growth and progression throughout their early years of life. Maybe a new pet needs to be tracked to help facilitate proper care. Maybe your carry-on luggage is on the cusp of being flagged and you want to ensure you’re good to, well, carry on. We like the Scale X from Waze for these various needs as the platform has multiple modes that facilitate proper data measurements without clouding up the analytics with unnecessary stats — we doubt you’d like to know the BMI of your carry-on tote.

Athletes also note that the companion app is easy to maneuver through for clear and concise readouts, but there is a little lacking when it comes to understanding each individual statistic. It would be nice for Waze to offer explanations on the varying metrics and why they mean in terms of body composition, but for a silhouette as versatile as this, you can’t expect all the background information to be there.
