The first wristband that recognises and tracks human emotions throughout the day.


Feel is the first wristband that measures and tracks your emotions throughout the day.


How Feel works

The integrated sensors on the wristband measure and track biosignals throughout the day, while the mobile application visualizes the results and provides personalized recommendations to improve emotional health.

Feel the wristband

4 integrated sensors on the wristband measure and track biosignals from users throughout the day, including galvanic skin response, blood volume pulse and skin temperature. The buckle on the top of the wristband hides a flexible connection which ensures that the bracelet stays stable on the wrist.

Feel the app

The modern wristband communicates directly with the user's mobile phone using Bluetooth. The mobile application visualizes the results to show users how they feel during the day and how their mood is affected by factors such as their activity, the people they meet, as well as the environmental conditions. The app also provides personalized recommendations to help users reduce stress and improve well-being.
