Frequently asked questions (FAQs)
With so many different manufacturers to choose from, you probably have a few queries about smart scales, but don't worry, we're here to clear up some of the most common questions.
Are smart scales accurate?
In terms of measuring your weight, smart scales should be just as accurate as any other scales you may have, if not more so thanks to their digital nature.
For body composition stats such as your body fat, they may not be as accurate as a test performed by a healthcare professional. However, what smart scales do provide is consistent measurements which you can use to track your progress over time.
For example, if you notice your body fat percentage going up, then you'll know that this information is probably reflective of the changes in your body and not to do with the scales becoming more inaccurate.
Are smart scales compatible with all devices?
The short answer is no as some smart scales are not compatible with iOS devices such as Apple Watches, for example. However, with the majority of smart scales, you're often asked to download an accompanying app on your phone which, once you step off the scales, will automatically receive the information it measured and store it on your device.
What features should you look for from a smart scale?
In addition to measuring your weight, smart scales can also calculate everything from body fat and muscle mass to BMI, and even sometimes your water percentage and metabolism.
These measurements can give you a clearer insight into your general health, and can also be used for tracking your progress toward your fitness goals.
As a result, we'd recommend searching for scales with these kinds of health-tracking features, particularly if you don't own one of the best fitness watches for men or women, for example, which can also deliver this kind of information
Do smart scales need to be connected to WiFi?
Not all smart scales need a WiFi connection to work. In fact, most will simply use Bluetooth to pair to a smart device such as your phone to send data and information.
That said, this may not be the case for all scales. As a result, we recommend checking the product description of a particular set to see whether they require a WiFi connection before you buy.
How long do the batteries last in a smart scale?
Battery life will vary depending on several factors, including the specific model, usage, and the type of batteries used. However, on average, most smart scales tend to have a decent battery life.
In fact, most smart scales tend to use AAA or AA batteries. With regular use, where the scale is used a few times a day, the batteries can last anywhere from several months to a year or more. However, if the scale is used more frequently or if it has additional features like body composition measurements that require more power, the battery life may be shorter.
It's worth noting that some smart scales come with rechargeable batteries or have built-in rechargeable batteries. In such cases, the battery life will depend on the capacity of the battery and how often it is used and recharged.
To get a more accurate estimate of battery life for a specific smart scale model, it's best to refer to the manufacturer's product specifications. Additionally, you may be able to prolong the battery life by turning off the scale when not in use or by using high-quality batteries.
