Display shape
The shape of the display provided in the design of the device. In this case, there are two main types of displays — round and rectangular. However, it is worth noting that such a division is very arbitrary, and the groups themselves are very extensive: for example, round displays are oval and egg-shaped, some of them resemble rectangles with extremely rounded corners; a classic rectangular display can be placed in a round case, etc. In addition, its shape practically does not affect the functionality of the display. Therefore, when choosing, you should focus not so much on the form as on the type of display (see below), the features of displaying various data on it and the general compliance with your aesthetic preferences.
Display backlight
The presence of
backlight in the design of the display, which is equipped with the device.
Its own backlight allows you to see the image on the screen regardless of the ambient light — in other words, such a screen can be used even in complete darkness. Most often, it turns on for a short time, by pressing a special button — this allows you to minimize additional battery consumption. The exception is displays built on the basis of OLED matrices — in them each pixel is a separate luminous element, the image glows constantly, and energy savings are ensured by high efficiency and some design and software tricks.
Individual settings
Personalized settings enable users to tailor the device to their individual characteristics. Modern fitness devices often incorporate the following customization options:
— Gender. Ability to set the gender of the user. With the same age, height and weight, the male and female bodies still differ in metabolic characteristics, optimal heart rate values and some other significant parameters.
— Age. Ability to set the user's age. This indicator primarily affects the general condition of the body and its ability to endure high loads (although these points also depend on other factors, ranging from physique to physical fitness, previous diseases, etc.).
— Weight. The option to input user weight is used in calculating optimal heart rate, energy expenditure, and fat burned (refer to "Possible measurements"). When combined with height, it provides insights into physique specifics and the need for weight management.
— Height. Ability to set the user's height. This indicator is practically not used on its own — it is usually used in combination with weight (see above) when determining physique. In addition, some pedometers (see “Type”) can calculate stride length from height data (although this setting is more common, see below).
— Step length. Ability to manually set the user's average step length. The main scope of this data is the calculation of the distance traveled in pedometers (see "Possible measurements")....
— Individual training area. Users can manually define an individual training zone, specifying the desirable heart rate range during exercise, with a warning signal for exceeding it. While many fitness gadgets can automatically calculate an optimal range based on workout goals and individual settings, certain situations, such as recovery after illness or exceptional physical fitness, may require specific considerations. Some devices with a heart rate monitor function enable users to manually set a personalized training zone, factoring in all relevant parameters.
