Best Smart Scales: Reviews & Buying Guide

With everything in our lives becoming connected, it only makes sense that the stuff in our bathrooms would follow suit. Smart scales are the most prominent connected device in that room of the house, and there are plenty to choose from. Connected smart scales sync with different apps on your smartphone to help you keep track of weight fluctuations and loss, body fat, and other health concerns. One thing to note, if you’re really interested in body composition data, you’re not going to find what you need on this list. To get accurate body composition data, a tiny amount of current is sent through the contact points of the scale. If you’re using a scale with no hand grips, it’s calculating an average based on current from one foot to the other, which leaves tons of room for error. If you want precise body composition, check out our Body Composition Scale Guide here.

You’ll notice that many of the smart scales are optimized for particular wearables or apps. For example, the Fitbit Aria 2 is designed for the Fitbit app and will be best matched up to Fitbit wearables. For some shoppers, the brand will be appealing. However, there are plenty of scales that don’t require wearables and/or will integrate into a variety of apps.

Which Scale Should You Buy?

For many shoppers, a current ecosystem (like Garmin, Fitbit, Polar, etc.) makes the decision-making easier. Sticking with a brand you know and already use is sometimes easiest, especially if you’re happy with how things work. Having the same brand will make pairing and sharing easier overall.

Other deal makers or breakers might be price or app integration. Several smart scales have very limited app compatibility, forcing users to stick to the proprietary app for best results. However, some scales, like our top pick, the Nokia Body+, are compatible with most of the top fitness apps out there (Nokia’s works with over 100).

If you’re looking to spend far less than the premium scale prices, there are plenty of good options that give you intensive data at a reasonable price. Both the Weight Guru scale and the Yunmai offer smart scale features at highly affordable prices.

Ultimately it comes down to the features and data you need, and what you want out of a connected smart scale. There are so many options that you’re sure to find one that fits your specific needs and budget.See Best Price

1. Withings Nokia Body+ Body Composition Wi-Fi Scale

Originally a Withings scale before Nokia’s buyout, the Body+ is a well-reviewed and relatively budget-friendly smart scale. It recognizes up to 8 unique users and will automatically update for each person. It is compatible with iOS and Android, and it offers Wi-Fi and Bluetooth connectivity.

The Body+ provides users with a comprehensive look at body composition by measuring and tracking:

  • Weight
  • Body Fat
  • Water Percentage
  • Muscle and Bone Mass

The app, known as Health Mate, offers tracking and trends and provides users a space to set goals, track nutrition, and manage a daily calorie budget. In addition to Health Mate, you can also integrate the Body+ and data into over 100 other health apps.

There is another smart scale from Nokia called the Body Cardio. It runs about $80 more, and, until recently, the primary difference came from something called Pulse Wave Velocity (PWV), which would measure the speed of users’ blood flow and provide additional data. However, Nokia is disabling that feature on the Body Cardio. There is now little difference between the two scales, and certainly not $80 worth of difference. The Body+ is your best bet.

2. Weight Gurus Bluetooth Smart Scale

There are a few reasons why the Weight Gurus scale is a smart buy. First, their customer service is excellent. Second, it’s priced right (under $50) and provides plenty of metrics, including:

  • Weight
  • BMI
  • Body Fat
  • Lean Mass
  • Water Weight
  • Bone Mass

It also pairs easily with most of the top apps, including Fitbit, Google Fit, Apple Health, MyFitnessPal, and more. The Weight Gurus scale automatically detects up to 8 unique users and transmits data privately.

With easy setup and a five year warranty, this is a scale that offers great features that will help you work toward your goals.

3. FitBit Aria 2

Of course, the biggest selling point for the Aria is that it comes from Fitbit. If you have a Fitbit, this will seamlessly pair with your app and data and make it simple to track your progress and changes. The Aria will tell you:

  • Weight
  • Body Fat Percentage
  • Lean Mass
  • BMI

The Aria supports multiple users (up to 8) and keeps individual data private. One difference between this (as well as the Nokia scale) and the less expensive scales is the ability to connect via Wi-Fi and not just Bluetooth. This offers better encryption and is just more appealing to some people.

There are plenty of complaints about the Aria, however. Many users find it to be buggy, and others have noted an inconsistency in measurements. The first Aria had plenty of issues, and Fitbits release of this second version had Fitbit fans hoping that all the kinks would be worked out. It doesn’t look like that’s entirely the case. The Aria might be worth the cost (around $130) for hardcore Fitbit fans looking for a simple integration into their Fitbit app. For others put off by the cost or the potential issues, there are other scales that will work with the Fitbit app, so you can definitely find an alternative.

4. Xiaomi Mi Smart Scale

Xiaomi Mi fitness bands are popular inexpensive fitness trackers that have grown in popularity over the past few years. Like the Mi Band, the Mi smart scale is inexpensive and does the basics without frills. It tracks weight and BMI and stores up to 19 user profiles.

It’s priced similar to the Yunmai and Eufy, but it doesn’t offer as much data as those two. However, for some shoppers, the Xiaomi name and app might be the big selling point – it’s very simple and convenient to use if you already have Xiaomi products.

The app and scale help you work toward specific goals (like weight loss) and you can add a bit more detail about your body shape and type, nutrition, and more. Reviewers note that it’s accurate and easy to set up.

5. Polar Balance Smart Scale

Technically this scale is called a “weight management service,” and it’s designed to work with Polar wearables (like the Loop 2 and others) and connect via Bluetooth. It logs your info and guides you toward your set goals. While it only provides weight and BMI, when used as that weight management service, it’s a smart and helpful idea.

When completely paired, the app will give you personalized activity goals that will help you meet your target weight. You’ll want to log food intake to ensure your goals and progress are accurately logged.

Essentially this scale is really only fully useful for those who are in the Polar ecosystem. While it will pair with MyFitnessPal, there are other scales that will give you more data or cost less. And, if you’re not utilizing Polar gadgets and apps already, there isn’t one big draw for this particular scale. However, if you have Polar already, this might be a great fit for you.
