Health is about way more than the number on your scale, so your scale should be smart enough to tell you more than just how much you weigh — like your your body fat and muscle mass percentages and even your heart rate and resting metabolic rate.

But not all of these devices are smart enough to be named valedictorian. Some smart scales are better with accuracy than others and different models have different features that you might think are really cool or totally unnecessary.

That’s why we researched all the best smart scales on the market and rounded up the smartest of the bunch. Keep reading to find out which smart scales graduated at the top of their class.

Your ideal match made in smart scale heaven depends on your goals and the functionality you’re looking for. We looked for models designed with different types of users in mind, all while checking off the boxes for important features like:

  • Accuracy. Most smart scales aren’t perfect. But they need to track their metrics as tightly as possible.
  • Ease of use. It should be “step on, get your reading, step off.” Not your parents trying to figure out Zoom for the first time.
  • User satisfaction. Ratings matter, people. If a scale doesn’t have a lot of love, we don’t want it on our list.

Omron Body Composition Monitor with Scale

  • Price: $$
  • Connects via: N/A
  • Syncs with: N/A
  • Power source: 4 AA batteries
  • Weight capacity: 330 lbs.

If you’re aiming for a very specific body fat goal, accuracy is everything. Enter full body Bioelectrical Impedance Analysis (BIA), which is the process of sending a low level electrical current through your body (nope, you can’t feel it). Different parts of your bod (like fat, water, and bone) slow down the current in different ways. The scale uses that information to determine various measurements like body fat percentage and muscle mass.

Most smart scales rely on sending an electrical current through your feet only. But the Omron Body Composition Monitor also features an upper body scanner that sends electric signals through your hands to get an ultra-accurate reading.

This smart scale measures:

  • weight
  • BMI
  • body fat percentage
  • skeletal muscle
  • resting metabolism
  • visceral fat
  • body age

Reviewers applaud the accuracy of the scale but complain the design is outdated and wish there was an app.

Weight loss is a marathon, not a sprint. And the Garmin Index S2 is designed to be your ride-or-die throughout the whole journey.

The Garmin Index S2 measures:

  • weight
  • weight trend
  • BMI
  • body fat percentage
  • skeletal muscle mass
  • bone mass

If you mean business with your fitness and fitness is your business, then Tanita may be for you. The company claims the BC-533 model uses exclusive BIA technology that gives stats as accurate as what you’d get from hydrostatic (underwater) weighing, which is typically considered the gold standard.

The Tanita BC-533 measures:

  • weight
  • body fat percentage
  • muscle mass
  • bone mass
  • body water percentage
  • metabolic age

Many reviewers highly recommend this scale. But some customers question its accuracy.

Smart scales tend to cost more than your average scale, so you want to make sure your choice is just as smart as your scale. Here are some tips for picking the best one for you.

  1. Know your numbers. Make a list of the metrics that are important to you and pick a scale that tracks them all.
  2. Sync up. If you’re committed to tracking progress in an app like Fitbit or MyFitnessPal, be sure to choose a scale that can share data with that app.
  3. Check your connection. Check the signal strength in your bathroom — or wherever you plan to house your scale — before opting for a scale that connects via Wi-Fi.
  4. Sharing is caring. Are there other people in your household that could benefit from a smart scale? If so, choose a scale that can accommodate multiple user profiles.

Here’s the skinny on how these scales outsmart the basic scale. Smart scales use something called bioelectrical impedance analysis (BIA). It sounds super science-y and that’s because it is.

When you step onto the scale, a little electrical pulse is sent through your bare feet and travels up through your body. (Don’t worry, you can’t feel it). Along the way, the impulse measures how much resistance it must go through.

Why does resistance matter? Well, it’s harder for electrical current to travel through fat than muscle and going through water is easy peasy. The scale takes the resistance measurements and plugs them into a fancy formula that considers your age, height, and sex and voila! You learn a lot more than just what your body weighs.

Smart scales give measurements related to your body composition, including:

But… are they accurate?

Short answer: unlikely. A 2021 study tested three smart scales against a DEXA scan and found they didn’t exactly calculate body composition accurately. And Consumer Reports tested six scales against a Bod Pod and again the smart scales didn’t measure up.

But that doesn’t mean a smart scale can’t still help you reach your goals. Using one consistently will show you if you’re trending in the right direction. So instead of focusing on any specific number, pay attention to whether that number is increasing or decreasing over time.

Smart scales aren’t your only option for measuring metrics to better understand your health. Here are some more tools to add to your techy toolbox.

  • Omron also makes a handheld fat loss monitor which is much more portable than a smart scale.
  • Lumen is a metabolic measurement device that analyzes your breath to let you know if you’re burning carbs or fat.
  • The Skulpt Scanner gives you localized body fat percentage and muscle analysis based on where you place it on your body.
  • The Bello Belly Fat Scanner analyzes and tracks visceral and subcutaneous belly fat.

Smart scales can give you weigh more information than a regular scale. And metrics like body fat percentage and lean muscle mass are usually better indicators of your overall health and fitness than body weight alone.

The accuracy of the technology used may still be in question but it’s not all about the numbers. If you focus on the trends instead of the digits, a smart scale can be a great tool to help you step up your health game.
