10 of the best smart scales, according to online reviews

The FITINDEX Smart Wireless Digital Scale is great if you will have multiple people tracking their measurements as the scale can accommodate unlimited users. Each smart scale user will just need to create their own profile in the FITINDEX app, which will then sync with their respective accounts on Apple Health, Google Fit, and Fitbit. 
While weight is the only measurement shown on the scale’s face, the other metrics (like muscle mass, BMI, and bone mass) are available to view in the app. Make sure you have the app open and your Bluetooth turned on to ensure the most accurate collection of data. The scale can store data so you’re able to sync up later, but some reviewers reported missing information when trying to sync that way. 
The scale is 10.2 inches by 10.2 inches, so it’s not the best if you have large feet. Some users also reported inaccuracies in the body fat calculations. The FITINDEX comes with 3 AAA batteries.
Amazon customer Kelly writes:

“I was really worried that the required app would be junk, but it’s actually very good. The trending is nice, it’s fast and looks decent. It does seamlessly put the data into Apple Health as well which is a nice bonus. Totally exceeded my expectations there.

The scale measurements seem to jive with the equipment at the gym almost perfectly so I’ve moved to using this scale at home for everything and not checking at the gym any more. I now can check my weight/body fat/etc at the same time every day (as soon as I get up) so it’s as consistent as it can be and any gains/loss will be more realistic.”

Overall, the FITINDEX scale is a good deal for what you’re paying. It has a 4.5 out of 5 star rating on Amazon and goes for $25.99. (Though the black option is $26.99.)

The Arboleaf Smart Scale is rated 4.8 out of 5 stars on Amazon. Reviewers rave about the scale’s accuracy and functions.
The Arboleaf can manage unlimited users — you’ll each just have to create your own profile in the app. The scale even remembers each user based on their body composition, so you won’t have to tell it who’s stepping on. The scale just knows. 
You don’t need to have your phone on you to record your insights, either. The scale stores your data and syncs up the next time you connect your phone to Bluetooth within range. A handful of reviewers expressed difficulty getting the Bluetooth to connect, but most had no issues.
Though the Arboleaf app syncs with Fitbit, Apple Health, and Google Fit, many Amazon reviewers like using the native app. It tracks 10 body measurements (including muscle mass, visceral fat, and metabolic age) and formats them in a way that motivates users. Not only does the app present you with the data it collects, it provides plans on how to improve and meet goals for each measurement as well.
This scale is equipped with four high-precision sensors and four sensitive electrodes to ensure accuracy in the readings, plus it also auto-calibrates and auto-zeroes. Bonus: The Arboleaf comes with three AAA batteries.
Amazon customer OkieMe writes:

“This scale has been great since day one. I’ve had it just over a week now. The scale itself seems to be pretty accurate. It weighed a mere ounces from my doctors scale. My old scale was 2-3lbs from the doctors scale. It would also fluctuate a few pounds within minutes of weighing. This scale has been perfectly consistent. Numbers are big, bright, and easy to read. The app is a bonus, and very easy to pair. I love how it graphs your progress and tells you more details with such a user friendly interface.”

The Arboleaf Smart Scale is accurate and pretty cost-efficient. Coming in at $39.99, this scale is on the lower end of smart scale pricing.

Body+ from Withings by Nokia is the smart scale for the tech-obsessed. It syncs with Apple Watch plus more than 100 health and fitness apps, including Apple Health, Fitbit, and Google Fit. The scale also greets you with the day’s weather forecast when you step on.
Up to eight different users can utilize the Body+ scale. Like some other smart scales, Body+ recognizes users based on their body composition, so there is no need to have the app open to your profile when you hop on the scale. You can sync your data via Bluetooth or Wi-Fi.
In addition to its standard settings, Body+ also has pregnancy and baby modes. Pregnancy mode allows you to monitor your body composition and nutrition as you go through a pregnancy while baby mode is designed to gather information about the babies or tots in your life to monitor their growth. (Of course, it goes without saying that no at-home smart scale should take the place of regular doctor’s visits — for you or your little ones.)
This scale is created by a trusted brand and while many reviewers claim that it is accurate, some have doubts about a couple of the measurements. Body+ runs on four AAA batteries, which are included with the purchase.
Amazon customer Brad C. writes:

“I bought this upon the recommendation of my doctor. While it tracks bone mass, fat mass, water percentage, BMI, etc., I’m not convinced of the accuracy of the additional readings. I doubt my bone mass and fat mass fluctuate by several pounds on a daily basis. In the plus column, it has a great app to show your history, and the app is compatible with several health and nutrition apps like Samsung Health, My Fitness Pal, Nudge, etc. It even recognizes the user so multiple family members can benefit from all of the features. I would definitely recommended this for those on any nutrition program.”

Body+ from Withings by Nokia has a 3.7 out of 5 star rating on Amazon. It normally goes for $99.95, which is a relatively low price for a brand-name smart scale.

The RENPHO Bluetooth Body Fat Scale tracks a whopping 13 metrics — that’s more than any of the other smart scales on this list. With all that data at your feet, you’ll know more about the makeup of your body than you probably ever thought you needed. 
To set up this scale, you’ll need to turn on your phone’s Bluetooth. Android 6.0+ users must also turn on their location services in order for the scale to sync up. The scale can track data for an unlimited number of users, just make sure your phone is either open to the app or that you’re the last to have synced before stepping on. Otherwise your measurements could be tracked under a different user’s profile. As long as no one else is connected, you will not need your phone to step on the scale. It will store your information until the next time you sync.
The RENPHO app allows you to share your progress with friends who use the app. It also syncs with Fitbit, Apple Health, and Google Fit. The scale runs on three AAA batteries, which are included.
Amazon customer Britney Brown writes:

“The accuracy of the scale is the only factor that has been less than perfect. Occasionally, I step on the scale twice within a few minutes to find the number has changed. This happens rarely and never more than a few ounces difference, but it is something to note if accuracy is your most important purchase factor. Overall, my measured weight matches scales at multiple doctors’ offices who have far more advanced, high-end scales so I have had no concerns about the overall accuracy and have continued to use the product daily.”

Reviewers said the RENPHO Bluetooth Body Fat Scale works as well as or better than more expensive scales. That being said, there are some signs that it is a cheaper option. Some reviewers said the $29.99 scale gave them different readings in back-to-back weigh-ins, though enough people are happy with the smart scale for it to earn a 4.3 out of 5 star rating on Amazon.

The Bluetooth Smart Scale by Greater Goods uses Bluetooth to pair with your phone, although you don’t need a phone to see your measurements as each one is displayed directly on the scale’s screen. You do need the Greater Goods Weight Guru app to track your data over time, though. The app syncs whenever you open it within range of the scale and also pairs with other fitness apps.
The Greater Goods scale has a tempered glass surface and can hold up to 400 pounds and is not intended for users who are pregnant or have electronic medical implants such as a pacemaker. 
Greater Goods partners with nonprofits to, you guessed it, create a greater good in the world. A portion of each scale purchase helps fund Love146, which fights to end child trafficking and helps care for survivors. So not only will you be helping yourself by monitoring your health, you’ll also be helping children in need.
As for accuracy, this smart scale nails it in the weight category, while some reviewers reported other measurements being a little off.
Amazon customer Allan writes:

“There are fluctuations, but it’s important to remember that these are just estimations using current technology. You’re looking for trends, not necessarily specific numbers. So far, the total weight is on par with my old regular scale and the breakdown seems about right given my current physique and fluid intake.”

The Greater Goods Bluetooth Smart Scale requires four AAA batteries, which are included in the box. The scale has a 4.2 out of 5 star rating on Amazon, and can be purchased for $49.85.

Something that sets the QuardioBase 2 apart from most other smart scales is its use of emojis. The scale uses Smart Feedback that “makes it easier to meet your goal” by replacing numbers with emojis that reward progress. The scale also greets you by name when you step on. 
Up to eight users can share the scale and QuardioBase 2 automatically recognizes each person so there’s no need to fiddle with the app before stepping on to get your measurements. 
Another feature that makes the QuardioBase 2 unique is its pregnancy mode. Pregnant users are able to set their due date and let QuardioBase track progress through each trimester with charts and a photo diary in the Quardio app. Note: Before using the smart scale, be sure to consult with a doctor as each body — and pregnancy — is different.
Amazon customer Patricia L. Huffman writes:

“The Quardio Base 2 has been a lifesaver during my pregnancy. Weigh-ins on my previous scale were getting me down, since the weight just went up and up. When I heard that the Quardio 2 has a pregnancy mode, I decided to try it out, and was so impressed. The setup was easy; the scale synced seamlessly with my iPhone and Apple Health app, and the dedicated pregnancy mode made the weight gain seem like a natural progression with a helpful division into 3 trimesters (and the smiley face on the scale is cute too!). I also love that the App lets me upload bump pictures with my weekly weigh-ins so I can see my progress. I’m looking forward to using the weight loss mode to get back to my pre-pregnancy weight — my husband has been using it to track muscle mass and body fat % and it’s great that the scale easily distinguishes between different users so that both I and my husband can use it.”

The QuardioBase 2 runs on a rechargeable battery that has up to a year of life. It is rated 3.2 out of 5 stars on Amazon and is listed for $149.

The Fitbit Aria 2 is one of the biggest names in the smart scale world. It’s the most convenient option for Fitbit users because there is no app middleman — it syncs directly to the Fitbit app (obviously). You can use Apple Health and MyFitnessPal to sync your data into other apps you might want to use.
The Aria 2 uses Bluetooth connectivity for initial setup, then relies on Wi-Fi for regular use. The scale can recognize up to eight users and sends each person’s data directly to their Fitbit account.
There’s no need to power on or calibrate the scale before each use — just step on and it’s ready to go. The Aria 2 displays each of your measurements on its screen, so you don’t need to have the app open to view them. However, you will have to step off the scale before it gives you a reading.
Amazon customer Jenna writes:

“Everything I expected. Extremely helpful to keep my weightloss goals in check. You are paying for the name brand here, as there are other smart scales that do the same/more, but if you are an active Fitbit user it is a must have.”

If you are an active Fitbit user, this smart scale should be an easy addition to your fitness arsenal and fit in seamlessly with the gadgets you already use. The Aria 2 is rated 3.7 stars out of 5 on Amazon and is listed for $129.95.

The Eufy Smart Scale is one of the more basic options on this list. While you have to have the app open and within range in order to use the scale, the EufyLife app syncs with Apple Health and Google Fit, so you are able to easily transfer data to other fitness apps you might use.
Up to 20 users can maintain profiles on the Eufy scale and it supports multiple device pairings, so while you will need the app open to receive your measurements, you will not have to reconnect every time you want to use the scale. This scale is suitable for people of all ages and has a 1.25-inch number display for easy reading.
The Eufy Smart Scale runs on four AAA batteries, which are included with purchase along with a 15-month warranty.
Amazon customer Tony L. writes:

“It only takes a second or two to determine how much you weigh, which is great. It also gives you estimates for a number of things including your BMI, BMR, water weight, lean body mass, bone mass, visceral body fat, and more, with some tags that let you know if those numbers are high, low, or excessive (I take those figures with a grain of salt, but they’re good indicators nonetheless). For anything other than weight, including keeping your log, you do have to have your smartphone with you, app installed and running, when you hop on the scale. That’s kind of a pain. Also, navigating the app, there are only a couple of measurements that you can see on a chart for the past week. I’d love to see them upgrade this so you can look at all of your measurements over any period you choose (e.g. week, month, year).”

Reviewers give the Eufy Smart Scale 3.8 out of 5 stars on Amazon. The scale is listed for $44.99.

The Garmin Index Smart Scale recognizes up to 16 users based on their body composition. All of your information is automatically sent to your Garmin Connect app and formatted into easy-to-understand data.
Each measurement is displayed directly on the scale, so there’s no need to have the app open every time you weigh in. The Index uses Wi-Fi to sync with your phone and the scale is powered by four AA batteries and has an average battery life of nine months.
The Index scale pairs seamlessly with Garmin fitness trackers and smart watches, making this smart scale ideal for runners who already use Garmin devices. Where reviewers have run into issues is pairing with other brands of smart watches.
Amazon customer saerom writes:

“My husband and I both use the Garmin Vivoactive and we’re both trying to lose a bit of weight so we were immediately intrigued by this scale. The set-up was a bit tricky, but now it works like a dream. I love how it immediately syncs the data to my phone through the Garmin Connect app and immediately see my progress over time. It’s super helpful to get the body fat percentage data, as well, since weight isn’t actually very informative. Now I have a weight goal as well as a body fat percentage goal. Great product if you already use the Garmin infrastructure!”

The Garmin Index has a 3.5 out of 5 star rating on Amazon. You can get it for $119.99.

The Yunmai Premium Smart Scale can host up to 16 users. However, for users who are younger than 18, the scale will only be able to record their weight. Yunmai also suggests speaking with your doctor first if you are pregnant or have electronic medical implants, such as a pacemaker.
For all other users, this scale will track 10 body metrics using BIA technology. Your precise results will be sent directly to the Yunmai 2.0 app where you can track and share your progress. The app data can also sync with Apple Health, MyFitnessPal, and Google Fit.
Setup is quick and easy. Just open the app, create a profile, turn on your Bluetooth, and hop on the scale. The app updates live as you step on the scale, so you can view your stats on both devices. Weight and body fat percentage are displayed directly on the scale while all other metrics are available in the app.
Amazon customer A. Gonzalez writes:

“I really like this scale, it has all the options I was looking for as well as having a good app to accompany it for the price I wanted to pay. The app integrates great with Apple Health which then feeds in my data into LoseIt.

The only issue I have with this product is the battery life, it’s not very good. It goes for about a month (few times a week use between my wife and I) before we have to change out the batteries. I ended up buying some rechargeable batteries because of this.”

The Yunmai Premium Smart Scale scored a 4.3 out of 5 star rating on Amazon. You can buy it for $71.95.
