old school scale weight

For many people, part of managing their overall health and fitness includes weight loss or maintenance. There’s been an increasing market for smart scales that work with the Fitbit app. 

If you are already a Fitbit app user, this is great news! And if you’re using the new Pixel watch that also integrates with the Fitbit app, even greater news!

It’s important to note that using a scale should never be the only means of managing your health, but it can be a great tool to use in addition to tracking your exercise and nutrition. 

Smart scales can also measure a whole host of other biometrics and seamlessly integrate them with apps on your phone. All of these components give you much more value and insight into your fitness journey than a regular scale could. 

In this article, we’ll explore some of the best smart scales that work with the Fitbit app and detail how you can incorporate them into your personal health and fitness journey.

  1. WYZE Smart Scale: Best budget option

  3. Fitbit Aria Air: Best simple and straightforward option
  4. Etekcity HR Smart Fitness Scale: Best customizable option
  5. Greater Goods Premium Wi-Fi Smart Scale: Best middle-of-the-pack option for price and features

What are the benefits of using a smart scale versus a regular scale?

First, since smart scales automatically sync your data to your phone, it’s much easier to track progress over time and stay on track with your fitness goals. And the Fitbit app and/or companion app show your trends and provide personalized insights to help you meet your health goals.

Fat and muscle mass detection

Regular scales often can’t distinguish between fat and muscle mass, which is crucial when progressing through a fitness journey.

To track body fat and composition, most smart scales use a safe, painless, low-intensity electrical current through your body (bioelectric impedance analysis or BIA) to determine how much of your total weight is fat-free mass and how much is body fat.

Some smart scales also track a host of other body measurements, including visceral fat, bone, muscle mass, and some even track your cardiovascular health.

One thing to note is that while your scale tracks many different body measurements, Fitbit limits its app to track just a few of these body measurements: height, weight/body mass, body mass index, and body fat percentage.

Additionally, recent research indicates that a smart scale’s body composition measurements are not as accurate as a DEXA scan from your doctor’s office. Smart scales tend to underestimate your body fat percentage and over/underestimate muscle mass.

We find that the best way to use a smart scale is to track your body measurement trends over time. When you consistently use the same scale, a smart scale is great at showing your progress or lack of progress in changing your body composition from month to month or year to year.

Tips to get the most out of your smart scale

  • Try to use the scale at the same time every day.
  • Don’t weigh in if you’re dehydrated or overhydrated. And avoid drinking caffeine or alcohol in the hour leading up to using the scale.
  • Don’t use the scale immediately after exercise or after bathing/swimming. Wait at least 30 minutes post-workout or post-showering.

WYZE Scale 

Wyze smart app

The WYZE scale is an excellent budget option for those who aren’t sure if they want to commit to spending over $100 for a smart scale. 

Don’t let its lower price fool you, though, because it is still quite feature-rich!

WYZE advertises its scale as a “Bluetooth smart body composition analyzer that tracks 12 essential body metrics.”

Those 12 body metrics include:

  • Overall weight
  • Body fat percentage
  • Heart rate
  • Lean body mass
  • Body mass index (BMI)
  • Muscle mass
  • Visceral fat
  • Basal metabolic rate (BMR)
  • Bone mass

These features really paint a comprehensive picture of your health and fitness. For example, it’s important to know your overall body weight but then be able to break down actual muscle mass and decipher that from fat mass. 

Wyze Scale S, Scale for Body Weight, Digital Bathroom Scale for Body Fat, BMI, Muscle, and Heart Rate, Body Composition Analyzer with App, Batteries Included, Bluetooth, 400 lb, White
  • WHOLE BODY COMPOSITION ANALYSIS - Health is measured by more than just weight. Wyze Scale S also...

The actual scale has an ITO-coated glass surface and a clear LED display for easy viewing. 

You can add up to eight unique users, and the scale remembers each profile as soon as you step onto it.

You can also share your stats with others via the WYZE app. PLUS, you can sync this to the Fitbit app if you prefer to view all your health metrics in one place.  


  • Measures 12 important biometrics
  • Offers results sharing
  • Up to eight unique users can make profiles with the scale
  • Lowest price for a feature-rich scale


  • The WYZE app is pretty basic, but if you plan to use the scale with your Fitbit app, then this is not an issue

Withings Wi-Fi Body Smart Scales

withings body comp smart scale

If you’re familiar at all with the health and fitness technology industry, then it’s no surprise that a Withings product is on our list.

Withings has created some of the best smart scales on the market, including the Body, Body+, Body Cardio, and their newest model, the Withings Body Comp.

All of Withings’ Body line of scales sync to the Fitbit app using the free Withings Health Mate app.

Withings Body+ - Digital Wi-Fi Smart Scale with Automatic Smartphone App Sync, Full Body Composition Including, Body Fat, BMI, Water Percentage, Muscle & Bone Mass, with Pregnancy Tracker & Baby Mode

You also get robust features like automatic syncing with Wi-Fi or Bluetooth, multi-user support for up to 8 people, weight and BMI information for each user, activity reports, long battery life between 12-18 months, and food tracking support using MyFitnessPal.

Some models like the Body+, Body Cardio, and the newest Body Comp also track your entire body composition and heart rate.

Withings also offers on its higher-end rechargeable models (read more expensive) that provide some additional features like heart rate tracking and a unique feature called Vascular age, that’s considered one of the best ways to assess your cardiovascular health.

The Body Comp is the model with the latest health features, such as new and improved biomarkers. Withings worked hard to add additional sensors and proprietary technology to provide more precise and accurate measurements of your body. 

These heightened sensors and new technology now provide the most comprehensive assessment ever offered on Withings scales.

These measurable metrics include:

  • Electrodermal Activity Score to assess overall health
  • Muscle mass
  • Fat mass
  • Water mass
  • Visceral fat
  • Bone mass
  • Cardiovascular assessment
  • Vascular age
  • Air quality report and assessment 

The newest and most intriguing feature is the Electrodermal Activity Score. The Body Comp can measure sweat gland stimulation in your feet and provide great insights about your overall gland activity and health.

It’s an interesting metric that is often influenced by diet and activity. 

With the Body Comp, you’ll also get 12 months of access to Withings’ Health+ in-app experience. Health+ provides workout and nutrition guides and encouragement.

It also delivers in-depth biomarker analyses to inform you about your overall health and progress.

Something to consider is that after your 12 months are up, if you’d like to continue using the Health+ feature, it’ll cost you $9.99/month. You can always unsubscribe if the time comes and you no longer wish to use Health+. 

You can sync Withings products with a handful of different health apps, which is why we think it is one of the best smart scales that work with the Fitbit app.

And if you ever decide to leave Fitbit for Apple, Samsung, or Google Fit, a Withings scale can go with you–it’s compatible with them all!


  • In-depth, highly-researched, and technology-backed biometric measurements and analysis 
  • Up to 8 users can create accounts on one smart scale
  • Comes with a free year of their Health+ feature (for the Body Comp model)


  • The higher price is definitely an investment 

Fitbit Aria Air

Fitbit’s own Aria Air smart scale is a simplistic but thorough option for those who don’t want to be overwhelmed by excessive metrics. 

If you value high-tech, feature-rich products, then this particular scale probably isn’t for you.

However, if you’re looking for a solid product that tracks your weight, integrates it into an app to show progress, and doesn’t break the bank, then the Aria Air could be your perfect match.

This smart scale is jam-packed with features and clever assessment tools.

Its smart customization also allows you to select which metrics you want to measure and have displayed on the scale’s screen.

This smart scale measures six body comp metrics:

  • Body mass index (BMI)
  • Body fat
  • Bone mass
  • Muscle mass
  • Water weight
  • Overall body weight 

Because it also uses Wi-Fi to integrate results from the scale, you don’t physically need your phone within reach when you step on the scale.

It’s also got some excellent physical features like a back-lit LCD screen, large numbers for ease of reading, and tempered glass with indium tin oxide coating, which is their secret to getting accurate measurements.
