Best for Pregnancy: Withings/ Nokia Body+
Because of the lack of research on using bio-impedance sensors, some smart scales are not pregnancy compatible.
But when you’re trying to keep track of your weight and body levels during pregnancy, having a smart scale can make your tracking much easier.
The Nokia Body+ is already one of the most-loved smart scales on the market, but it’s also one of the top choices for pregnancy.
This is one of the few smart scales to offer a pregnancy-specific reading. In the app, along with weight, muscle mass, and body fat, you can also use the pregnancy tracker mode.
This mode tracks your weight gain during your pregnancy and tells you if you’re in a healthy range. It also delivers a weekly report with pregnancy-specific health information tailored to your specific trimester.
We can’t recommend another smart scale more for pregnancy.
Nokia Body+ Pros

Smart Scale Buyer’s Guide
Buying a smart scale might sound easy, but it’s more complicated than clicking “buy” on Amazon.
There are always tons of new features debuting every day, and some people may be keen on certain features over others.
Here are some of the main components of a smart scale that you should keep in mind.
The most important aspect of tracking your body levels is the accuracy of the results.
A fancy smart scale is no good if it doesn’t do its job, and that’s tracking your weight, BMI, and other measurements and accurately sending it back to your mobile app.
Usually, the best way to know if a smart scale is accurate is by checking user reviews online and cross-checking your numbers with your physician.
A smart scale should be able to pull together all of your levels quickly and accurately.
App Ease of Use
The primary reason to get a smart scale instead of a regular scale is to track your data seamlessly with your fitness app on your smartphone.
The user-friendliness and ease of use is a critical part of using the smart scale.
You may have a favorite fitness app that you already use that you want to integrate with your smart scale. Smart scales like the Eufy BodySense and the Nokia Body+ make this easy because they are compatible with several fitness apps.
If you use fitness apps like Google Fit or Apple Health, check with the scale manufacturer to see if the scale is compatible.
On the other hand, if you are a Fitbit or Garmin user, you may want the Fitbit Aria 2 or Garmin Scale for optimal app integration.
Most smart scales also come with an app that you can download if you don’t already use a fitness app. For example, the Nokia Body+ has the app Health Mate, which offers several types of readings and fitness tracking options.
Some of the better apps offer personal trainer features, calorie intake trackers, and other weight loss features that allow you to utilize the smart scales data.
The way your smart scale transfers the data to your smartphone depends on the type of connectivity it has.
There are two ways to connect: via Bluetooth or WiFi. The type you should choose depends on your personal preference.
Here are the differences between Bluetooth and WiFi:
- Bluetooth: Some smart scales use a Bluetooth connection to transfer the data to your mobile app. These scales are usually less expensive because they don’t rely on an internet connection to work. However, if your phone isn’t nearby while you’re using the scale, you may not be able to sync the results. Some Bluetooth smart scales can save the results and sync the results once your smartphone is nearby.
- WiFi: Some scales use your home’s WiFi connection to transmit the data to your phone. While this is a convenient feature, most smart scales need a strong, encrypted open WiFi connection to work. If you travel with your smart scale and need to connect it via WiFi, it may not work.
Generally speaking, with smart home products, people tend to prefer a WiFi connection. However, having a WiFi connection isn’t always the better choice, depending on your lifestyle. Both WiFi and Bluetooth are good options for most people.
With all digital bathroom scales, the best type of display is big and bright with clear numbers.
The display should be big enough to view measurements without needing to squint or bend to read the numbers. If you ever plan to use the scale at night, the display should be visible in the dark.
Most smart scales displays show big, bright numbers with a backlight clear enough to view regardless of the amount of light.
Of course, you will get the full breakdown sent to your phone, but for quick weigh-ins, the display is important.
The size of your smart scale is important for several reasons.
People usually have their smart scales sitting out in their bathroom or their bedrooms. If the size is too big or the scale has a weird shape, it might not fit.
If the size is an issue for you, remember the scale’s dimensions in relation to your bathroom when you’re looking at options.
Almost every smart scale has a weight limit of 400 lbs or 180 kg.
A few out there that have less, but the standard weight limit to see is between 350-400 lbs.
If you or someone you know weigh more than 400 lbs, realize that you might need to look for a specialized scale orthat you may not get accurate results.
What Can a Smart Scale Measure?
The reason for getting a smart scale is to track more than your body weight.
What a specific scale can measure depends on the brand. Some scales can measure up to 16 aspects of your body composition. Generally speaking, you’ll get at least four or five measurements.
Here are some of the things smart scales measure.
Basal Metabolic Rate (BMR)
Your basal metabolic rate is the number of calories your body uses while it’s at rest to properly function. A higher BMR measurement means your body burns more fat while it’s seated and sleeping, which is a helpful way to lower your body fat percentage.
If you’re on a fitness journey, your BMR is a helpful measurement to track your progress when it comes to the energy levels and the amount of muscle.
Most apps will use your BMR to tell you how many calories you should consume in a day to keep your BMR higher and your body fat lower.
Scales that calculate your basal metabolic rate:
- Eufy BodySense
- Yunmai Smart Scale
Body Fat Percentage
Tracking your body fat percentage is an important part of many fitness gurus and muscle builders. The number tells an exact percentage of the body fat divided by your body mass.
You can also get this metric through the bioelectrical impedance reading. Health professionals claim that this is a more accurate metric to rely on compared to your BMI.
Scales that calculate your body fat:
- Eufy BodySense
- Yunmai Smart Scale
- Fitbit Aria 2
- Garmin Index Smart Scale
- Nokia Body+
Body Mass Index (BMI)
There is a lot of debate on whether body mass index is a useful measurement to track. Many doctors say that BMI isn’t a reliable or accurate measurement to determine if someone is healthy because it relies on your body mass and height divided by your weight.
A lower BMI doesn’t always necessarily mean that you’re a healthier person. Some people with lower BMI scores may be unhealthier than someone with a higher BMI because it also depends on the amount of muscle you have.
Despite the controversy of the reliability of BMI, many people still use this number to track their weight loss and fitness journeys. Every smart scale should have this measurement as an option.
The most straightforward measurement is your body weight. This is calculated in pounds or kgs.
Check with the manufacturer to make sure it’s easy to change the scale between kg and lbs for different users.
Body Water Percentage
Your body water percentage is how much water you have in your body.
The normal range is about 50-65% in men and 45-60% in women. You should aim to have this level of water in your body for your organs to properly function.
A smart scale with this metric will help indicate when you need to hydrate more.
Scales that calculate your body water percentage:
- Eufy BodySense
- Yunmai Smart Scale
- Nokia Body+
- Garmin Index Smart Scale
You may already have a fitness tracker that reads your heart rate, but having your heart rate sent to your fitness app through your smart scale is convenient.
Tracking your heart health with other metrics helps you monitor your health.
Smart scales can use the bioelectrical impedance analysis to obtain this number. It then sends your heart rate to your fitness app.
For easier ways to track your heart rate, check out the best heart rate monitors on the market.
You calculate lean body mass by subtracting your amount of body fat from your body weight.
Many smart scales can calculate this number by generating your body fat percentage. The scale sends a tiny electrical impulse through your foot. This impulse, called bioelectrical impedance analysis, goes through your tissue and can give you more specific and less-common readings.
Scales that calculate your lean mass:
- Eufy BodySense
- Fitbit Aria 2
Some scales can calculate other metrics. Possible options include:
- Body age
- Bone composition
- Bone mass
- Daily calorie intake
- Muscle mass
- Muscle rate
- Visceral fat
Warning: Because many of these upscale metrics rely on the electrical impedance, anyone who is pregnant or has a pacemaker should not use these smart scales. Double check with your manufacturer if this applies to you, and always read the manual to make sure. If you are pregnant, use a Nokia Body+ or another scale that has a mode specifically for pregnant women.
