The 8 Best Smart Scales of 2025, Expert-Approved

Smart Scales We Also Tested 

We tested 40 smart scales, but only eight impressed us enough to earn a spot on our final list of recommendations. While these smart scales didn't quite make the cut, they do have some notable features.

• Sportneer's Smart Scale is intuitive, easy to use, and pretty precise. However, the weight-to-height ratio it recommends is on the lower side than what is generally considered healthy, which could trigger some users.
  
• QardioBase's X WiFi Smart Scale boasts a great display and stores a lot of data, but we don't think it's worth the money due to its inaccuracy and inconsistency during testing.
• iHome's Smart Scale is easy to set up, and data syncing was seamless, thanks to instructions in the app. However, we noticed inaccurate and inconsistent readings throughout testing, even after recalibrating. So even at the budget-friendly price point, we don't think it's worth it.
• We found Urevo's SmartFit Scale has very accurate weight tracking, and a clear, uncluttered display. Unfortunately, the Bluetooth connection was glitchy and inconsistent. And the scale lacks the ability to sync with other health apps, making it less versatile than other options.

What We’ve Updated 

• Since publishing our initial tested roundup of the best smart scales, we’ve re-evaluated our previous picks and hands-on tested nine additional options from top, trusted brands. Based on our testing, we’ve evaluated each smart scale for its precision, setup, ease of use, readability, data storage, and value, and incorporated these new insights into our article.  
• Based on our testing insights, we’ve reworked most of our superlatives and product picks, including Best Smart Scale Overall, Best Budget Smart Scale, Best Investment Smart Scale, and more. 

What to Look for When Shopping for Smart Scales

• Fitness App Compatibility: Many smart scales come with their own weight-tracking apps. If you already use a third-party app you love, look for a compatible scale to avoid losing your data.
• Bluetooth and Wi-Fi Connectivity: Bluetooth smart scales require you to have your smartphone within range to log your metrics successfully. Wi-Fi-enabled smart scales tend to be more reliable and easier to use, as Bluetooth can be unpredictable. Some scales have Bluetooth and Wi-Fi connectivity for integrating Amazon Alexa or Google Home.
• Metrics: Most smart scales track so much more than just your weight. Choose a scale that tracks data points that are important to you, whether that's your body mass index, muscle mass, body fat percentage, bone mass, or another statistic.
• Weight Capacity: All scales have a maximum weight capacity. Before purchasing, ensure your scale can hold the weight of everyone who will use it.
• Data Storage: One of the biggest perks of choosing a smart scale over a standard scale is the ability to record your metrics, track your progress, and view your numbers later. When purchasing a smart scale, check its data storage capacities. Look at how many users it can hold, how many measurements it records, and how easy it is to keep track of your progress.
• Ease of Use: If your scale is difficult to use, you won't be motivated to add it to your daily routine. Ensure the setup process is straightforward and that the scale is compatible with the right technology for your smartphone, third-party apps, and Amazon Alexa or Google Home devices. Also, look for a large, clear display that's easy to read.

How We Tested the Smart Scales

To find the best smart scales, we spent over a month hands-on testing 40 options, using each one once per day. When testing smart scales, we evaluate each option based on the following key criteria.

• Setup: To evaluate setup, we unbox each smart scale, download its corresponding app, and pair it with our smartphones. We think about how easy the process is and how long it takes. We prioritize smart scales that are easy and intuitive to set up, with clear instructions.
• Precision: To evaluate the precision of each scale, we weigh ourselves several times. First, we check our weight on a standard scale. Next, we step on the smart scale. Then, we hold a 5-pound dumbbell and weigh ourselves three more times. Does the number on the display jump by five pounds? We note whether the smart scales read the same as the analog scale and whether our weight remains consistent throughout the test.
• Readability: For any scale to be worth it, you need to be able to clearly read the data it displays. While standing on each smart scale, we note how easy it is to read and interpret our weight. Is the display well-lit? Can we read it from a distance? Can we read it in various lighting? 
• Data Storage: Your scale needs to have the capacity to record and store your metrics. During our test, we test each smart scale's data storage and user profiles. We prioritize scales that offer 10 or more data points other than weight, can record data for at least 10 users, and have a compatible app that easily tracks and stores metrics. 
• Ease of Use: To earn a high ease of use score, we prioritize scales that don't require recalibration or additional instructions, like tapping your foot on the scale before use.  
• Value: To accurately assess each smart scale's value, we don't check the price until the end of the testing period, after we've evaluated each option in all other key categories. Based on the scale's performance, do we think it's priced fairly? Or would we only buy it if it went on sale? We also consider whether we'd recommend the scale to a friend or family member.

Our Experts

We consulted experts at each stage of our research, testing, and reporting process. The following experts helped us understand how smart scales work, their accuracy, and what measurements they can provide. While we choose products independently, input from experts influences our decisions.

Frequently Asked Questions

How do smart scales calculate body fat?

Smart scales calculate an estimated body fat percentage using bioelectrical impedance. Sensors in the scale send an undetectable electric current from one foot through your body to the other foot. The slower the current, the higher the fat percentage.

How do smart scales measure bone density?

Smart scales measure bone density through a dual-energy X-ray absorptiometry (DEXA) scan. Bones are poor conductors of electricity compared to other body tissues, so electrical current resistance allows smart scales to calculate bone mass, says Karpukhin.

Should you get a Wi-Fi or Bluetooth smart scale?

Wi-Fi-enabled smart scales will sync your data as long as you're connected to a Wi-Fi router, while Bluetooth-enabled options require you to have your smartphone (or another Bluetooth device) within range to track your metrics. If you prefer convenience and reliability, opting for a smart scale with Wi-Fi connectivity may be better, but keep in mind that these tend to be pricier than Bluetooth options.

Can smart scales be wrong?

In general smart scales are accurate when it comes to weight. However, some research suggests that body composition, including body fat and muscle mass, is often associated with errors due to incorrect foot positioning, foot size, and sweat. To get the most accurate reading possible, be sure to follow your scale's directions very carefully. Contact your healthcare provider if you're concerned about any of your readings.
