These scales are considered “smart” because they track dimensions other than your weight, like ,  and . The scales also connect to your phone and sync up with fitness apps like Apple Health and Google Fit. This makes it easier for you to track your overall health data. That’s why getting a premium smart scale may be worth the investment if you’re trying to meet health and wellness goals and want to see data about progress beyond just weight.  

One thing’s for sure: These scales keep getting smarter. To break down the best smart scales on the market, I first established a control weight, recorded at a recent doctor’s appointment, to compare against these scales. Then I tested them in my bathroom daily, weighing myself multiple times on each scale at the same time of day for two weeks. Taking into account each scale’s consistency, accuracy and measurements provided, I determined which are worth buying. Before purchasing, take a look at our top picks for smart scales below. 

QardioBase X is our top pick because of its customizable functions and ability to be used on different surfaces. Admittedly it’s large and heavy (weighing about 7 pounds), but the sleek design makes it an appealing piece of technology, even if it’s just a scale. It’s compatible with Wi-Fi and Bluetooth, can be recharged with USB-C and it can read units in kilograms, stone and pounds. It has a weight capacity of up to 396 pounds. It’s suitable for up to eight users and has several modes to pick from, including one for athletes and one called “out of sight” if you don’t want the weight to appear on the scale. It also has modes for pregnant people and people with implanted devices, avoiding potential harm or interference by turning off the electrical currents used by most smart scales to read metrics aside from weight. It’s one of the few scales that functions well on any surface — even a carpet — which is always a plus.

This scale from Renpho is the best option if you want a user-friendly smart scale app. The scale uses both Wi-Fi and Bluetooth, which is helpful since it means you can save your data in Wi-Fi mode and sync it up later via Bluetooth. This sleek, black design doesn’t look as fancy as the other high-end scales on the list, but it’s the right size to store in your bedroom or bathroom. The weight capacity is capped at 396 pounds, meaning various people can use it. It’s battery-powered, so if you want a rechargeable scale, this may not be the best choice for you. This scale provides unlimited user profiles and is suitable for weighing infants and adults alike. It’s important to note that, unlike most of the other scales on this list, this one does not have a mode for pregnant people or those with implanted devices.

It may not seem like a big deal, but the way a scale shows a reading on its display screen can make or break your experience. This is especially true if you have vision issues or are tall and would like your scale to have larger fonts for easier reading. Etekcity’s HR Smart Fitness Scale has the best display screen because the high-resolution graphics make it easy to read your weight, and it depicts a custom set of key measurements on the screen (so you don’t have to go to the app every time).

The Withings Body Plus scale is a good option if you want the ability to sync up to over 100 third-party apps like Apple Health, Google Fit and MyFitnessPal to your scale. It’s a large, sleek mirrored glass scale that has four high-precision sensors to give you the most accurate readings. It can record eight user profiles and hold up to 396 pounds. It uses pounds, kilograms and stones measuring units so it works for various individuals. This may not be the ideal scale for pregnant people or those with implanted devices because it does not provide a specific mode that turns off electrical currents. This scale connects to both Wi-Fi and Bluetooth and is easy to set up. The scale comes with carpet feet, which can be placed at the bottom of the scale on each corner. The carpet feet weren’t my favorite accessory because sometimes the scale wobbled on my tiled bathroom floor and I had to reposition it until the surface felt even.
