I will tell you a secret. I’m not too fond of bathroom scales, smart or not. I find them depressing, and they always look at least 10 pounds wrong. I also found it really weird that my shirts are gradually shrinking. Don’t you have the same feeling?

What is great with the best smart scales we selected is that they go far beyond measuring the weight. They connect wirelessly to your phone and provide tons of data about the body composition, body mass index (BMI), heart rate, and can even track your weight gain during the pregnancy.

They are far less depressing than Grand Ma’s bathroom scale but are instrumental in any weight loss strategy or just for health and fitness. We tested models ranging from $20 up to $200. Is the huge price difference really justified?

What are the best smart scales for 2020 that deliver the best bang for the bucks? We selected three of the best models that we think will reconcile you with your weight and will certainly be your best allies to start the year 2021 with many good resolutions.

RENPHO SMART BODY FAT SCALE

Best value

The Renpho smart body scale comes in two flavors: Standard or Premium and two colors: black or white. The main differences between the models relate to the technology used to measure the body parameters.

The standard model relies on classic bio-electrical impedance sensors. The premium Renpho scale will take advantage of Indium tin oxide (ITO) directly integrated into the tempered glass to provide a sensor free, more stylish look. The use of ITO technology is also more accurate than the classic metal pad.

We have not been able to verify this claim tough. Our opinion is that the choice should be based more on the esthetic than on technology. The $10 difference is modest, though.

The electrodes of the Renpho Premium Smart Scale are directly integrated into the tempered-glass for a more stylish look.

What is bio-electrical impedance?

All smart scales use bio-electrical impedance to send a low-level current between your left and right foot. The flow of this imperceptible current will be affected by the amount of water within the body.

In a nutshell, the fattier the tissues, the slower the transmission. By estimating the ratio between water and fat, clever algorithms will extract various data about the body’s precise composition.

Use the app. to analyze your body and reach your goals

The app. is available on the Apple Store and Google Play and connects via Bluetooth to the scale. No need to bring your phone with you when measuring your weight and other data.

The scale will store the data and send them via Wi-FI to the app. Good to know that your home WIFI should be at 2.4 GHz as it is not compatible with 5GHz networks.

The Renpho scale is even smart enough to recognize up to eight different users and store the data accordingly.

Being compatible with most of the standard Health and Fitness apps, keeping track of your weight and body composition will become an integral part of your daily routine.

Track your body without breaking the bank

On top of the standard weight, BMI, and percentage of Body Fat, the Water Percentage, Fat-free Body Weight, Skeletal Muscle, Muscle Mass, Bone Mass, Visceral Fat, Subcutaneous Fat, Protein, Basal Metabolism, and Body Age are also measured.

The app. will offer plenty of graphs and statistics for data lovers. Most of all, synchronization with Google Fit, Apple Health, or the Fitbit app is a great way to monitor your fitness, define specific goals, and monitor the progress while staying motivated.

The Renpho smart scales are powered by three AAA batteries that will last. In our opinion, this smart scale is a well-designed product that will answer all of your body composition, fitness, and weight measurement needs without breaking the bank.

Withings is not new to the world of smart scales. They currently offer three models, the Body, Body +, and Cardio, that offer various physiological analyses. The Body + is the company flagship and has all we can expect from a modern smart scale.

The design is stylish, and the minimalist design will fit any bathrooms or gym clubs. The tampered glass comes in white or black. The scale weighs 4.4 lbs and is only 0.9-inch height. Despite being light and slim, it feels like a high quality built. The LCD screen is bright and easy to read, even in bright daylight.

No more reason to blame the scale

Precision is not taken lightly by Withings. The Body + offers a “position control” technology to ensure that the scale is properly adjusted and your stance optimal to deliver accurate readings.

Four arrows will light up in the corner of the screen if you need to adjust your feet a little bit for the center of gravity to be where it should and the measures to be as highly precise as possible.

The Body + also adjust the gravity of the earth depending on your location. Star Trek fans will certainly understand these subtleties better than I do, but the measurement will be perfect (in a 0.2 pounds range).

QARDIOBASE 2

Best for style

The QardioBase 2 is the last on our list of best smart scales for 2020. We loved the design, the accurate measures, the pregnancy mode, the compatibility with implanted medical devices. Despite a price point higher than the previous two nominees, we consider that the innovative design and technologies fully justify the price point. The QardioBase 2 is different from other smart scales and is the first step into the future of weight tracking.

A new approach to weight measurements

With its circular shape and lack of screen, the QardioBase 2 doesn’t look like a classic scale. The 14.57 inches glass circle comes in white and black.

The information is displayed in the center of the scale using a range of bright green LEDs for easy reading. The scale also offers haptic feedback when the measures are completed.

If looking at a number feels depressing, you can also display the results using a smiley. We think it is a great way to stay motivated and not to feel any guilt when using the scale.

Different modes for different needs

The QardioBase 2 is easy to set up and pair via Bluetooth and Wi-FI with the Qardio app. for iOS or Android. The app will ask you to choose between four smart modes: Normal, Weight only, Smart Feedbacks, and pregnancy.

  • Normal mode: Measures for your weight, BMI, body fat %, muscle, water, and bone mass,
  • Weight mode only: The bio-impedance functions will be disabled in case you have an implanted device such as a pacemaker,
  • Smart Feedback mode: Our favorite one. The progress and information will be displayed using smileys,
  • Pregnancy mode: The weekly evolution of the pregnancy will be displayed. The app. also offers the possibility to app photos for memories.

Multi-user friendly

Like the other smart scales on this list, the QardioBase 2 can also detect up to eight users and record their measures accordingly. Unlike most of the scales, the QardioBase 2 comes with a micro-USB for charging the rechargeable battery that will last up to 12 months.

The scale can recognize up to eight users automatically and will even remember their favorite mode.

At $149.99, the QardioBase 2 is the most expensive smart scale we tested. Considering all of the new features, this price is fully justified for high quality and truly different scale.
