The sensor itself doesn't directly affect your body, but serves solely to record and analyze your posture. It also helps you regularly remind yourself to maintain an upright sitting position.

Please note, however: If you have any health restrictions that affect your mobility or make sporting activities difficult, we recommend that you consult your doctor before performing the exercises included in the app.

Basically, the sensor can be worn while exercising and helps you track your posture.

Please note that the sensor is not waterproof, but only water-resistant. Excessive sweating or water sports should be avoided while wearing the sensor.

The sensor is water-repellent but not waterproof.

Even if the sensor slips inside your sensor shirt, it continues to provide data about your posture. Depending on how much the sensor has slipped, the data may be inaccurate.
However, the sensor shirt was designed to always place the sensor directly on the spine and it is hardly possible for it to slip.

Your data is safe with us. We store your husbandry data on a German server under strict GDPR-compliant conditions.

Based on the collected sensor data, the app creates a personalized training program that specifically addresses your needs. If the system detects weak points in specific areas of your spine, you'll receive appropriate, short training sessions that specifically contribute to strengthening and relieving tension.
All exercises were developed in collaboration with experienced sports scientists – for effective, safe and sustainable back training.
