Stress Guide

The stress coach in your pocket: Measure your stress index using just your smartphone camera, 
and complete in-depth courses on stress-related topics.

Scientifically valid measurement

Stress measurement is enabled via the smartphone camera, which determines the user’s cardiovascular vital data and, based on this, analyzes the individual stress profile.

In-depth courses and exercises

We offer you stress-related courses and exercises that help you to reduce your stress and live a healthier life: Whether through a guided meditation, a deep breathing exercise or a life-changing tip.

Technologically innovative, mobile & medically valid vital data measurement

The technology behind our measurement 

Place your finger on the smartphone camera and flash, and hold still. After successfully calibrating, the vital data measurement will begin.

By illuminating the fingertip, the change in the blood vessels can be analyzed. Incoming blood appears darker, whilst outgoing blood appears lighter.

Based on these changes, vital data, such as pulse rate, is analyzed and used to determine the HRV (heart rate variability) and stress resistance.
