Sporty, slim tracker with room for individuality
The Fitbit Charge 4 gives men and women a choice: they can choose between standard variants with a silicone wristband and the special editions with a textile strap. The basic models are available in black, wine red and black-blue. In the somewhat more upscale versions, the fabric strap can appear either in an anthracite tone or also in black. These also come with an interchangeable silicone strap.
As is usual for Fitbit, the look of the Charge 4 can also be customized. The manufacturer from San Francisco offers additional straps that are available in various colors as well as in silicone, textile and genuine leather. The watch face, the tracker’s digital watch face, can also be customized. A number of analog and digital designs are available for this purpose. The Fitbit Charge 4 is waterproof up to 50 meters and can therefore also be used for swimming without any problems.
The first Fitbit fitness wristband with GPS
For the first time, Fitbit has added a GPS sensor to one of its fitness trackers. This makes recording outdoor activities much more convenient, as the cell phone does not have to be part of the game. The wristband automatically records disciplines such as running or cycling and collects important data such as the specific distance and speed. New sports such as kayaking, canoeing, snowboarding and skiing are also introduced on the Charge 4.
After a workout, users will find a workout intensity map in the Fitbit app. In it, they can track their completed distance and view the different heart rates to see how they changed over the course. Furthermore, the Charge 4 facilitates training according to a desired intensity. To do this, users define the respective goal of their unit.
Based on this, the wristband provides guidance to burn fat, work on endurance or improve performance. The wearable supports its owners in everything from classic jogging to power yoga and HIIT training.
Incidentally, the fitness wristband recognizes the so-called active zone minutes. This parameter is based on recommendations from the World Health Organization (WHO) and states that at least 150 minutes a week should consist of moderate exercise or up to 75 minutes of sport. This can provide the perfect foundation for physical health, a stable immune system, and healthier sleep and mental performance.
It should not go unmentioned that the Fitbit Charge also knows the number of steps taken per day, the corresponding distance and the amount of calories burned. On top of that, it reveals the number of floors climbed.
Wake up better rested, track your health and be ready for everyday life
Like its predecessor, this fitness wristband has also received a SpO2 sensor that determines the oxygen level in the blood. This tool makes it possible, for example, to detect abnormalities at night that indicate problems with sleep apnea. A detailed analysis of the night’s rest is also one of the capabilities of this tracker. With a sleep score, the wristband makes it easier to assess sleep quality. Meanwhile, an intelligent alarm clock is designed to let wearers start the day in the morning in a phase of light sleep – then waking up is perceived as much more pleasant.
Women, meanwhile, have the option of tracking their cycle with the Fitbit Charge 4. All users have the option to control their nutrition via the wearable.
In everyday life, the wristband informs its users at any time when a message or call arrives on the paired smartphone. A new feature of this fourth generation is support for Spotify. This allows music playback on the cell phone to be conveniently controlled via the wrist. Thanks to the NFC chip, contactless payment via Fitbit Pay is possible at supporting cash registers. The wearable’s battery life is up to seven days.
