As technology continues to evolve, so does the world of fitness. One of the latest innovations in this space is the smart fitness scale. These scales offer a wide range of features and benefits that can help you monitor your fitness progress, set and achieve goals, and stay motivated. But the availability of numerous options in the market makes it overwhelming for you to choose the right one. In this blog- “How to Choose the Right Smart Fitness Scale (Read this First)” we will provide you with some essential factors that you need to consider when selecting the best smart scale.

The Way Smart Scales Function

A smart scale uses bio-electrical impedance analysis to measure body composition, including BMI (Body Mass Index), BMR (Basal Metabolic Rate), and metabolic age. These metrics can help you better understand your overall health and track changes over time. But BIA (Bioelectrical Impedance Analysis) is not always 100% accurate and might be affected by factors such as hydration level and body position.

Consult your doctor before using a smart scale if you have an electronic medical implant such as a pacemaker. Smart scales can automatically track and log this information, making it easier for you to monitor your progress and integrate it into your health and fitness routine. Overall, a smart scale can be a valuable tool for improving your health and wellness.

Considering Factors While Choosing the Right Smart Fitness Scale


While it might seem logical to choose the most accurate smart scale based on body composition measurements, it's important to understand that no smart scale is perfectly accurate beyond weight. While they might have a wide margin of error compared to medical-grade methods like DEXA, smart scales are still useful for home use. BMI, BMR, and metabolic age readings are based on averages, so the closer you are to the average body type for your age and gender, the more accurate the results are likely to be. But athletes and very overweight individuals might receive less accurate readings.

Metrics Tracked

Smart scales can provide anywhere from five to 15 metrics, depending on the specific model. These can include body fat percentage, muscle mass, bone mass, body water percentage, visceral and subcutaneous fat levels, BMI, BMR, and metabolic age. Some more advanced models can even measure pulse wave velocity to give insights into vascular health.

App Compatibility

Using a smart scale's full range of features usually requires downloading and using its app, which allows you to view your measurements and track longer-term trends through graphs. Some smart scales can also offer the option to sync data with other health apps and platforms like Apple Health, Samsung Health, and Google Fit, making it easier to keep all your health and fitness data in one place if you use a fitness tracker or smartwatch.

Data Security

When purchasing a smart scale, it is important to prioritize data privacy and security since smart scales store sensitive health data. Research reputable brands with a track record of prioritizing data privacy and security, and look for information on their privacy policies and security features. Password protection and encryption are security measures that can be used to protect your data. Be mindful of the data you share with the app associated with your smart scale, review the app's privacy policy, and only share data that you are comfortable with. It is better to err on the side of caution to ensure that your sensitive health data remains protected.


Smart scales can connect to your phone via Bluetooth or Wi-Fi. Bluetooth scales offer quick set-up, but have a shorter range and require your phone for logging. Wi-Fi scales have a longer range but can take longer to set up and might not be as convenient if the Wi-Fi connection is unreliable. Your choice will depend on your preferences and requirements. It's important to consider convenience and ease of use before purchasing a smart scale.

Shared Use

When purchasing a smart scale for shared use, choose one that supports multiple user accounts. Differentiating between users can vary, with some requiring users to open the app to weigh in, while others assign the weight to a specific account. If multiple household members have similar weights, it can be better to choose a Bluetooth-connected scale that requires the app to be open when weighing in.

Smart scales can also be used to weigh babies and pets, but body composition measurements should not be used for children or teenagers. Smart scales are safe to use during pregnancy, and some models have a dedicated pregnancy mode.

Displayed Measurements on the Scale

Smart scales typically have a white or red LED display that usually only displays your weight. To see the rest of your measurements, you'll need to check the app. While some people see this as a downside, regularly logging weigh-ins in the app is essential to getting the most out of a smart scale. It also ensures that your data is accurately assigned to your account if you're sharing the scale with someone else.

Scales that display multiple measurements on the LED display can cycle through them one at a time, making it easy to miss the information you want or difficult to figure out what's being shown. If you prefer to see all your measurements on the scale itself, you'll likely need to invest in a more expensive device.

Power Source

Two ways are available in which you can power smart scales. Some models require four AAA batteries, which is similar to traditional bathroom scales. Conversely, some models have a rechargeable battery with a USB connection. The former option is cheaper initially but it might end up costing more in the long run due to the need to frequently replace the batteries.


When selecting a smart scale, consider the materials used in its construction. Look for a scale made with safe and durable materials that are easy to clean and maintain. Choose a smooth, flat surface that can be wiped clean with a damp cloth, and avoid scales with crevices that trap dirt and grime. Look for high-quality sensors and components that resist wear and tear to ensure accurate readings over time. A scale with these features will last longer and provide consistent, accurate results every time.


When choosing a smart fitness scale, consider its size and design to ensure that it fits well into your space and meets your aesthetic preferences. Look for a compact and lightweight model if you have limited space, and consider the size of the display. Many smart scales feature a sleek and modern design that can complement a range of decor styles. Some models have unique design features, such as a circular or square shape, or a hidden display. Choosing a smart scale that fits your space and aesthetic preferences can make it a more functional and visually pleasing addition to your home.

Ease of Use

Select a device that is easy to use and contains clear and easy instructions.

Weight Limit

When choosing a smart scale, check its weight limit, which is usually around 400 pounds. If you or someone in your household weighs more than this limit, choose a scale that can accommodate higher weight capacities, with some models supporting up to 550 pounds or more. It's also important to note that exceeding the maximum weight limit can affect the accuracy of the scale. So, it's essential to choose a scale that can comfortably support the user's weight without exceeding the maximum weight limit for the most accurate readings and a longer lifespan for the scale.

Brand Reputation

When selecting a smart fitness scale, it's essential to consider the brand reputation. Choose a reputable brand with a track record of producing quality products and providing excellent customer support.


Smart fitness scales come at different price points. Before making a purchase, determine your budget and find a scale that fits within it. Keep in mind that the most expensive option does not necessarily mean the best. You can get an affordable smart fitness scale within the price range of BDT 2000 to BDT 4000.

Final Words:

By now you must have become well aware of how to choose the right smart fitness scale. Remember, the key is to find the most accurate smart scale that measures the metrics you want to track and has a user-friendly app and robust security features.


How can a smart scale understand the difference between fat and muscle?

Ans: A typical bathroom scale works by measuring the physical force placed upon it when you step on it, which translates into your weight. But a body composition scale operates differently. It uses a method called bioelectrical impedance analysis (BIA) to determine the amount of fat-free mass and body fat in your body based on how it conducts electricity through it.

Is a smart scale safe to use?

Ans: While bioelectric impedance analysis (BIA) is generally considered safe for most adults and children, it's important to note that the electric current used in this method could interfere with certain implanted medical devices such as pacemakers. If you have one of these devices, it's recommended that you avoid using a smart scale that utilizes BIA technology to avoid potential health risks.

How protein is measured by smart scales?

Ans: A smart fitness scale uses a low-level and safe electrical current that passes through your body from the scale’s base. As the electrical current flows through the body's water, fat, bone, and muscle mass at different speeds, the scale measures these speeds to determine how your body is composed of these elements.

Can smart scales accurately measure fat percentage?

Ans: A study suggests that the body fat percentage measurements provided by the smart scales or body fat scales were found to be inaccurate in assessing body fat. All three smart scales used in the study underestimated both body fat percentage and absolute fat mass.

How can a smart scale measure metabolic rate?

Ans: Smart scales cannot directly measure metabolic rate, but some might estimate it using predictive equations based on factors like age, gender, weight, and height. But the accuracy of these estimates can vary, and they should not be relied upon as the sole measure of metabolic health.

How can a smart scale determine BMI?

Ans: Bioelectrical impedance analysis (BIA) is a method used by digital weight scales to estimate body composition. This technology involves sending a safe and painless electrical signal through the body. The signal flows more easily through water and lean tissue, such as muscle than through fat.

How often do you need to use a smart scale?

Ans: For the most consistent readings, it's recommended to use your smart scale every morning after emptying your bladder and before consuming any food or drinks. Wearing as little clothing as possible can also help ensure more accurate measurements. Remember that your weight can fluctuate throughout the day, so using the scale at the same time each day can help provide a more reliable and comparable measure of progress. Again, since the body naturally loses water weight overnight, using the scale in the morning might result in lower readings compared to using it later in the day.

How long can a smart scale last?

Ans: The lifespan of a smart scale depends on factors such as the quality of materials used, frequency of use, and maintenance. A high-quality smart scale can last for several years with proper care and maintenance. It's important to follow the manufacturer's instructions for use and care, which might include wiping the scale down regularly and avoiding extreme temperatures or moisture. With proper care, a smart scale can provide accurate and reliable measurements for several years.
