Fitbit equips the Fitbit Sense with an EKG function and a stress measurement via the skin resistance. A subscription service helps with data analysis.

The Fitbit Sense suggests changes in the Fitbit universe in many ways. The watch itself remains the most important collector of body data, but the company, which Google bought last year, puts more weight on the evaluation – from which Google says it does not want to benefit. The interpretation of the fitness data for the Sense is divided into two parts: a free one, which covers the most important basic data, and the Fitbit Premium, which is subject to a surcharge and which also contains a wide range of advisory components.

More advice on the basis of concrete data sounds plausible: Many platforms only offer flat encouragement for more activity and even complain about a step goal not achieved when you are currently doing a sweaty 80 – completed a km bike tour

The Fitbit Sense is less aimed at sports data collectors than at people who keep an eye on their well-being and also want to evaluate health data. The watch comes up with a phalanx of sensory measurements that other manufacturers sometimes do not offer: These include, for example, an electrodermal skin scan, which is supposed to provide information about the stress level of the wearer, as well as the possibility of creating an EKG to detect atrial fibrillation, for example. The app even creates a PDF with health data and one with the ECG history for the doctor’s visit.
