The story of the Nokia / Withings Body + connected scale is not simple. The model was designed by the French company Withings, when Nokia acquired it in 2017 the product was renamed, but at the end of 2018 it regained its original name.
The Withings Body + connected scale is a mid-range with an aesthetic and modern design with a well-thought-out LED screen. It is available in several colors to match your tastes as best as possible. The Scale measures only five data points, but it does so accurately and avoids unnecessary information. For example, you can have information on your weight, your fat mass, your BMI, your water mass. A recent update even allows to know its vascular age, true more of the scale.
The Withings product is compatible with Apple Health and also has its own Health Mate mobile application, which is a smart home device. Weighing is intuitive since the scale helps you position yourself correctly for high accuracy. It also has a gravity compensation system to avoid guesswork and give you the best possible information. The weight scale keeps up to 8 people in memory, which is more than enough for family use.

RENPHO ES-CS20M The Bluetooth scale that everyone enjoys
[content-egg module=AE__amazoncom template=custom/bigcart_notitle next=1]Known for its quality connected scales adapted to small budgets, the Renpho brand offers with this scale a state-of-the-art device while being accessible.
With its simple black design, the scale fits into any bathroom. Thanks to the 13 indicators, you won’t run out of data on your weight. The scale analyzes all types of elements among them: fat mass, bone mass, body age, subcutaneous fat or visceral fat. The 4 high-precision sensors of the scale provide you with a detailed analysis of your body composition.
The RENPHO application centralizes your data, enter your goals and check your progress! If you want to share your progress with your friends, you can! Although this connected scale only works with Bluetooth, if your smartphone is turned off, synchronization will take place as soon as it is turned on. No user limit for this weight scale.
If battery usage puts you off, you can turn to the Renpho ES-CS30M which offers similar functionality just the difference of charging. The latter is equipped with a rechargeable USB function, just connect your scale to one of your electronic devices to put it to charge.

Garmin Connected Index S2 The best Garmin connected scale
[content-egg module=Amazon template=custom/bigcart_notitle next=1]
[content-egg module=Amazon template=custom/bigcart_notitle next=1]
Mainly known for its GPS and connected watches, the American manufacturer has recently offered a quality bathroom scale with an autonomy of around 9 months with its 4 AAA batteries.
The understated black or white design is nice, if a bit standard for a product in this range. The LCD screen is the perfect size especially since the characters are displayed in big size, which is handy especially if you don’t have your glasses on.
The Garmin S2 scale becomes really interesting when it is linked to the dedicated Garmin Connect app. Each user must necessarily create an account before weighing themselves. You will therefore not be able to really make your guests try it. The data from the impedance scale are very good. The six measurements: BMI, body fat rate, muscle mass, bone mass and water mass rate are accurate and sufficient. The weather forecast has been added compared to the previous version.
You can register up to 16 users, that’s a lot, but you have to believe that it has become a hot figure for digital scales. The connected scale supports a maximum weight of 181.4 kilograms, which is about average, but for an impedance scale of this price we would have appreciated a little more.
You can find our test here to learn more about this very good scale.

Fitbit Aria Air The ultra-modern connected electronic scale
[content-egg module=Amazon template=custom/bigcart_notitle next=1]
Released in August 2019, this scale remains in the tradition of the Fitbit Aria 2 but differs through a well-crafted design. This is the third connected scale from the Fitbit brand.
Immediately we notice its very refined design that stands out. White or black in color, it contains no graphics but it has a screen showing the numbers when you weigh yourself. The numbers appear in white so there is no problem with legibility.
The functions of the Fitbit Aria Air are after all quite similar to those of its sister Fitbit Aria 2. However, this model does not take into account Wi-Fi but only Bluetooth and does not indicate the fat mass which is regrettable . Track your BMI through the Fitbit app, Aria Air syncs all your data to the app, find it as graphs to help you see more clearly.
For about half the price of the Fitbit Aria 2, find a modern connected scale that will undoubtedly help you stay in shape. In particular thanks to its very well designed application and its compatibility with the brand’s connected watches and bracelets.

Xiaomi Mi Composition Scale Glass 2 Xiaomi’s new model
[content-egg module=Amazon template=custom/bigcart_notitle next=1]
The Chinese brand is on all fronts. We had already introduced you to the Xiaomi surveillance camera, the Xiaomi LED bulbs and now here is their second connected scale also known as “Mi Body Fat Scale 2”.
The quality of finish is once again at the rendezvous. The sober white design is characteristic of the sign. The LED display blends in perfectly with the scale. The Xiaomi bathroom scale works thanks to an easy-to-use app. The product connects via Bluetooth 5.0 allows you to measure 13 different data instead of the ten metrics of the previous version, for example protein level and body type. In addition to that, this scale can weigh food or parcels, a 2 in 1 asset not to be overlooked!
The scale works with four batteries which provide an autonomy of 8 to 12 months. This figure varies depending on the number of daily measurements. It’s a family model, it keeps in mind up to 16 people, it’s huge and it doesn’t have to be very useful. Finally, we were amazed by the precision of the measurements since the Xiaomi scale will give you your weight to within 50 grams thanks to its G-shaped sensor.
What (s) difference (s) from the Xiaomi Mi Composition 1? Very good quality glass and the addition of sensors for improved operation.

The Best Precision Scales
Are you athletic and want to improve your performance? So take a look at precision balances. These are high quality models that provide very precise and therefore more reliable information on your metabolism. So you can adjust your workouts accordingly.
Tanita RD-953 The reliable bathroom scale for athletes
[content-egg module=Amazon template=custom/bigcart_notitle next=1]
To start this comparison on precision balances, we have selected the Tanita personal scale. It is a model for the general public, but it offers almost professional services. Despite a glass plate, however, the design is quite ugly, it’s too futuristic and a bit cheap. The RD-953 is available in three colors: red, black and white.
The product is guaranteed for five years, which is huge compared to the competition and reassuring. Once paired using Bluetooth, you can weigh yourself.
The LCD screen isn’t the most successful on the market, but it’s readable and that’s about all you ask for. Via the application you will have access to more than ten measurements: Weight, fat mass rate, muscle mass, muscle quality score (measurement exclusive to the Tanita brand), water mass, BMI, bone mass …
It is particularly comprehensive and the data is all very accurate, especially the muscle data. This is a significant asset for athletes who wish to obtain information on their physical condition. The MyTanita app is intuitive and has been greatly improved in terms of interface and content since its release a few years ago.
In short, it is a very complete precision balance which is intended above all for athletes.

Withings Body Cardio : The precision scale that measures the pulse and calculates the IMG
[content-egg module=CjProducts template=custom/bigcart_notitle next=1]We have already told you the tumultuous history of the Nokia / Withings smart scales, but this is the model that has been affected the most. When Nokia acquired Withings, the cardiovascular measurement function was discontinued. It was a big blow, because it was one of the only scales to offer this function. Fortunately, she was restored by Withings in 2018.
The Body Cardio is a classic and elegant model, its tempered glass plate and its white or black color are the most beautiful effect. The LCD screen specific to the Withings range is successful, it is readable and even displays the weather. The scale is capable of performing seven measurements including BMI, weight, fat mass, pulse, water and muscle mass …
The scale accuracy is 100 grams for weight, which is correct and average. For other data, it’s another thing, because the connected scale is very sharp, especially for the pulse. It supports a maximum weight of 180 kilograms and can hold up to 8 people. It is a precision scale for the general public less complete than the Tanita, but which offers useful measurements, especially at the cardio level.

Buying Guide: How to choose the best smart scale?
Definition scale (for weight): What is it? What’s the point ?
It might not be the device that will bring you the best news, but it is an essential item for staying healthy. Classic personal scales (or weight scales) will only give you your mass. It’s limited, but useful if you want to start a diet.
The impedance scales are a real asset to monitor your health thanks to its many measurements. Calculating body water, for example, tells you if you are hydrated enough. BMI takes your height into account. For athletes, it is a tool for getting to know your body better and making better progress. For a normal user, this is a way to stay in better shape.
A connected scale is also part of the smart home device. You can control it by voice command and access your data online. It is a way to centralize in the information of your connected home.
What are the best brands of diagnostic scales?
After dozens of hours of testing and analysis, here is the list of the best scale manufacturers of the moment: Xiaomi, Fitbit, Withings, Tefal, Tanita. You will find in our comparison their best respective bathroom scales.

How much does a smart scale cost?
You will find in our special file the best smart scale classified by characteristics and by price. Here are the different price ranges to know when buying a scale:
– For less than $25 you can find a good quality electronic scale. Don’t expect surgical precision. The device will not be connected either. For occasional home use, this is often sufficient.– Between 25 and 100 dollars, you will find the greatest number of products. The first connected smart scale cost between 35 and 40 dollars, at this price, precision is often lacking.– The models with the best price-performance ratio are in the range of 50 to 75 dollars although there are many exceptions. This is the right price for regular home use.– At more than 100 dollars, you will find very sophisticated connected scales. These models are not for everyone. The price is high and some options become unnecessary for a normal user.– From 200 dollars, only semi-professional scales are left for sports clubs.
Frequently Asked Questions Before Buying a Digital Personal Scale
How does a scale work?
It all depends on the scale model you are using. Some scales calculate weight and others calculate mass. Second, not all scales work the same. A digital scale needs a load cell, a strain gauge, and electromagnetic force. A mechanical scale like the Roberval scale works with a beam.
What is impedancemetry?
Impedance measurement is the measurement of the body’s resistance to a stimulus such as sound pressure or electric current. In this way, one manages to obtain more subtle information than the mere weight of a person. As such, BMI and IMG are among the most popular for analyzing your weight curve.
How does an impedance scale work?
An impedance scale works using electrodes. They activate on contact with the feet and deliver a very weak (imperceptible) electric current. You should therefore avoid turning the device on if your feet are wet. The electrical impulse will more or less meet with resistance. It is from this resistance that the level of body fat, BMI, body water will be measured …
What are the parameters for losing weight?
If you want to lose weight, opt for an impedance scale that calculates the IMG, in other words the rate of fat mass or body fat. It is mainly from this data that you will be able to lose weight and build muscle. This requires a healthy lifestyle and regular sports activity.
When and how to weigh yourself?
For the most accurate measurement possible, you should weigh yourself at the same time each time. A daily weigh-in is not essential, we recommend that you do it weekly. Regarding the best time to measure, we recommend that you do it in the evening before going to bed or in the morning on an empty stomach after going to the bathroom.
Why is my scale showing “Lo”?
The “Lo” message consists of the first two letters of “Low”, which means the battery is low and the batteries simply need to be changed.
Are impedance scales reliable?
Consumer-grade connected impedance scales are not worth the measurements made by professionals. Many variables can change the data and that is why you can have two different results after two simultaneous weighings.
Personal impedance scales are very interesting for monitoring changes, so be sure to always use them at the same time of the day.
Can I use my phone as a scale?
You can find applications on your laptop’s store that supposedly can calculate your weight. These applications are not effective. They either have very poor precision, or they are completely false. Nevertheless, one can find quite effective kitchen scale applications. To find out more, visit our dedicated comparison.
How can a digital scale calculate water mass?
The hydration level is a percentage of the total body mass. It takes into account the fluids that circulate in your body, mostly made up of water. So it’s good to be aware of this when weighing yourself, since it’s not about fat. Thus, the scale sends an alternating current of 500 to 800 micro-amps, in the feet, and the resistance it picks up allows it to perform the correct calculation. In short, it is the same principle as for fat mass!
Is the Beurer BF700 scale a good alternative?
We did not choose the Beurer BF700 scale despite its commercial success, because its performance is not / no longer as good. The measurements are not always precise, it is not particularly ergonomic.
Most importantly, the Beurer bathroom scale is very intrusive. In order to function properly, it needs access to a lot of your personal data, which is not reassuring.
What is a Roberval scale?
The Roberval scale owes its name to Gille Personn de Roberval. It is an instrument that dates from the 17th century. It was used to weigh an object, a food, a material against tares. Roberval scales were useful for retail.
They are not scales. They were gradually replaced by other faster and more precise scales.
Connected Balance and Quantified Self?
The quantified self or self-measurement in French is a device for analyzing and sharing personal health data. The quantified self model algorithm sometimes uses data from other users to optimize its performance. Many models of connected scales work thanks to the quantified self.
Is there a risk for my personal data with a connected scale?
Connected scales like all networked products present risks of data leakage. To date, there is no article reporting a proven misappropriation of personal information. If you are concerned about the Big Data phenomenon, we recommend that you invest in an unconnected weight scale.
How to calculate your fat mass?
Don’t go into endless calculations to calculate your body fat. An impedance scale does the work for you automatically thanks to the multiple built-in sensors. Most connected scales have a sensor for fat mass because it is of course an essential element that we want to have available to monitor or lose weight.
How to lose fat mass?
Your precision scale is the ideal companion to reduce your body fat. This is because the linked application provides you with insight into your data around your weight day after day. It often allows you to enter your goals to keep motivation at the top.
How to adjust an electronic bathroom scale?
If you have a problem with your connected scale, here’s how to fix it:
– remove the batteries from the back of the scale then wait a few minutes– put the batteries back in their original place, checking that they are in the right place– place the scale on a flat surface– put one foot on the scale to turn it on again, then step onto it completely until the weight is displayed again
Is a connected smart scale worth it?
Yes, a smart scale is worth it especially if you are looking to know details beyond your simple weight. An intelligent scale is ideal for seeing changes over time, with all the data accumulated the evolution becomes more concrete. It is witnessing the evolution of your figure that is the main asset of precision balances. In addition, for a reasonable price, you have access to completely qualitative scales.
How to clean your smart scale?
By dint of being placed on the ground, the scale, connected or classic, tends to catch dust. A simple cleaning with a microfiber cloth and water is enough to keep your scale in good condition as long as it is done regularly. Otherwise white vinegar is quite suitable. Note that the color black will tend to get dirty more easily than a light color such as white.
Which smart scales are compatible with Fitbit?
The Fitbit app is a great tool: all your health data in one app. Linking it to a compatible scale in addition ensures that you have your weight information and keep track of your trends. The scales compatible with Fitbit in our comparison are the Withings Body +, the Renpho ES-CS20M and of course the scales from the Fitbit range.
What are the best Apple Health compatible scales?
Apple Health is the official health app for the iOS system. Find your scale data on your iPhone anywhere and anytime thanks to synchronization. The best connected scales compatible with this app in our comparison are therefore Withings Body +, Renpho ES-CS20M and Tefal Body Partner.
What are the best Samsung Health compatible scales?
Samsung’s official health app is only compatible with certain scales. To find your data on your Samsung, the best compatible scales are the Xiaomi Mi Composition Scale 2 and Withings Body +. But others can also synchronize with your health app such as the Garmin or the Renpho,
Which connected Withings scale to choose?
The range of Withings connected scales consists of three models: Withings Body, Withings Body + and Withings Body Cardio. We recommend the Body + presented in this comparison. Why ? It gives the body composition unlike the Body in order to better target your efforts or simply to know your body better. Body Cardio is more recommended for regular athletes because it measures heart rate and pulse wave speed.
Balance in Bluetooth or Wi-Fi: which solution to adopt?
Connected scales can be compatible with Bluetooth, Wi-Fi, or both. Concretely, compatibility with Wi-Fi remains ideal. Indeed, the Wi-Fi signal is stronger than the Bluetooth * one, so the data will be synchronized more easily if your device is in another room of your home.
* Remember that the range of Bluetooth 4.0 is approximately 60m while the range of Bluetooth 5.0 is approximately 200 meters.
Which scale to choose for pregnant women?
The electric current delivered by the sensors of the connected scale is safe, but it is still better to take precautions when it comes to pregnant women. The digital scale that we recommend during pregnancy is the Withings Body + Wi-Fi scale. With the Health Mate app which contains a Pregnancy Guide, keep track of your weight changes and more during this time and get expert advice.
Notice: What about the FitTrack Dara scale?
According to some surveys, the FitTrack Dara digital scale looks exactly like another unbranded bathroom scale that sells for much less. And it’s not just on the surface, since the performance leaves a lot to be desired, with a hell of a lack of precision in the measurements, a very inconsistent application and an abysmal gap between the technology announced and that which has been observed. There is only one conclusion: we do not recommend the FitTrack Dara and advise you to buy a connected scale from a “recognized” brand such as those present in our comparison.
Opinion: What about the Tefal Body Partner?
A number of feedback indicates that the scale is difficult to use, imprecise, with an application that is yet to be developed. The product remains functional, but progress on the part of Tefal should be considered to avoid further disappointments!
