Fitness trackers are increasingly used to detect medical problems. The manufacturers of these models, which mostly appear in the form of watches, no longer come only from the health sector. Smartphone manufacturers such as Apple, Samsung and, more recently, Xiaomi have also presented smartwatches that go beyond simply counting steps and calculating calorie consumption.
However, these standard functions are still on board, as well as the sleep analysis, which provides you with a detailed breakdown of your nights in terms of deep sleep, light sleep and REM sleep phases. However, additional sensors and evaluations now give you a broader picture of your fitness and health.
Heart rate and oxygen saturation become standard
Heart health has come into particular focus. Therefore, almost all current fitness trackers and watches measure the wearer’s heart rate – in the case of the angular ones
Fitbit Versa 3
for 230 euros even automatically around the clock. If you like it a little cheaper, you can go to
Fitbit Inspire 2
to grab. The fitness bracelet costs just under 100 euros, but does without GPS and color display, among other things.
For the same price (100 euros) you can also get them
Xiaomi Mi Watch
with round 1.39-inch display as well as heart rate and SpO2 sensor. The latter measures the oxygen saturation of the blood and, in conjunction with the sleep analysis, can also alert you to nocturnal breathing pauses, the so-called sleep apnea. You can see the progress of your breath in the smartphone app.
They are also equipped with an SpO2 sensor

from 420 euros, the
Garmin Venu
for 300 euros that
Honor Watch ES
for 100 euros and the
Samsung Galaxy Watch 3
which can be bought from 320 euros. And also the current top watches from Fitbit and Withings, the
Fitbit Sense
for 330 euros as well as the
Withings Scanwatch
for 280 euros, have an SpO2 sensor.

As a special feature, for 100 euros you have the option of making an EKG directly on the watch. For this purpose, the manufacturers equip the models with a special app directly on the watch, which you can use to take the measurement.
The implementation is very simple and completely harmless: You start the corresponding app on the watch and place your hand on the watch case according to the instructions of the wizard. The measurement takes about half a minute, you can then see the evaluation in the smartphone app as a curve (in the picture: Withings). You will also receive an assessment or evaluation of the measured values and information.

Even more help: recognize and reduce stress
As the

and the
Garmin Venu
The Mi Watch also includes a breathing assistant that is supposed to help you calm down with guided breathing exercises in stressful situations. The duration of the exercises can be adjusted.
The Fitbit Sense goes one step further: In the associated smartphone app, it offers a menu item “Stress Management” in which you are informed of your stress level based on your heart rate variability (HRV), physical activity and sleep rhythm.
Under “Mindfulness” there are guided relaxation exercises that use the EDA sensor of the Fitbit Sense. This measures the electrodermal activity, which indicates stress. You can also enter your mood manually in the app.
The sleep analysis also receives an additional measurement with the Fitbit Sense: The watch measures the nighttime skin temperature on the wrist and determines fluctuations.
