Feel recognizes and tracks your emotions
throughout the day.


How Feel works

The integrated sensors on the wristband measure a variety of bio-signals, while the mobile app provides personalized recommendations and coaching to help users improve emotional well-being.

Feel the Wristband

Four integrated sensors on the wristband monitor a variety of physiological signals such as, electrodermal activity, blood volume pulse, and skin temperature, while proprietary algorithms on the background translate those bio-signals into emotions.

Feel the App

The Feel app is the best way to manage your emotional well-being goals. It syncs with the wristband to track your emotions throughout the day and with your calendar to help you understand what triggered your mood. The app also offers advice and exercises, based on Cognitive Behavioral Therapy, to help you achieve your wellbeing goals.
