Essential for some, hated by others. The scale is a useful product to help us monitor changes in our body weight. Although it is not advisable to become obsessed with the data it produces, as several variables must be taken into account that can influence profits and losses, it does not hurt to keep an indicative record.

Like many other devices that we use on a daily basis, scales have also succumbed to new technologies and there are models capable of measuring several values, in addition to being able to synchronize them with our smartphone and health platforms or specific applications.

The scale market is vast. If you’re not sure where to start, in this selection we review the available types and recommended models for use with our iPhone and Apple Health service.

Types of scales

Before starting with the list of recommended models, it is worth knowing the types of scales available or, at least, the most popular and that people usually have in their homes.

Mechanical (or analogue) bathroom scale: the “eternal” bathroom scale. It can work both with an elastic spring and with a counterweight and it is a needle that indicates the weight. It’s the cheapest of all, but not the best option if you’re looking for a specific result. Their strong point, besides the price, is that they are very resistant.

Digital (or electronic) scale: this is the most common type today and there are fairly inexpensive models. It is characterized by a screen that displays the weight numerically. It stands out for its precision, since the margin of error is around 100 grams. It uses electronic sensors to determine body weight. If you have to give it a but, it’s its autonomy. Being battery powered, their battery life is limited, but they usually last for several months before needing to be replaced.

Bioimpedance Scale: If you want very good accuracy and more data besides weight, this is your type of scale. In fact, it is currently most popular for being able to calculate overall weight, body mass index (BMI) and muscle mass, as well as water percentage. It is very useful for athletes who need to know this information to give everything in their training. It works by emitting a low-intensity electric current that travels through the lower limbs to determine their resistance. This resistance depends on the water in the body, which has a constant proportion in the muscle mass (73% of the muscles are water).

Digital and bioimpedance scales can be connected, i.e. synchronized with a smartphone application via Bluetooth or Wi-Fi and share data with it and certain health services. Some of the most popular services are Apple Health, Google Fit or Samsung Health.

These scales can also have other very useful functions. Two of the most interesting are user recognition and memory:

User recognition: there are scales capable of registering several users with their own weight, height and age so that when they step on it, they automatically detect who it is.

Memory: With this feature, the weight of several sessions is saved as well as (possibly) other data related to height, gender or age.
