Your body reveals stress before you feel it. The eSense Skin Response measures electrodermal activity (EDA) on your smartphone or tablet—giving you real-time insights to train your nervous system for lasting calm.
The eSense Skin Response transforms your smartphone or tablet into a professional biofeedback device. By measuring electrodermal activity (EDA)—also known as galvanic skin response (GSR)—through simple finger sensors, you get instant, accurate insights into your stress levels. Skin conductance is the gold standard for stress measurement, used in clinical research and therapy worldwide.
Track your progress with real-time graphs, receive feedback through audio tones, music, videos, or even smart bulbs (Philips Hue™, Magic Blue™). Export your data as CSV for detailed analysis. Whether you're new to biofeedback or an experienced practitioner, the free eSense App guides you every step of the way. Tablets like iPad offer a larger display—ideal for professional use.

It offers a modern interface with real-time graphs, guided procedures, and multiple feedback modes including video, music, tones, vibration, and smart bulb control. Optional premium features and subscriptions are available for advanced training programs and cloud synchronization.
Electrodermal activity (EDA) is one of the most reliable indicators of autonomic nervous system arousal. Your skin's electrical conductance changes in response to stress—even before you consciously notice it. This makes EDA biofeedback exceptionally effective for: • Stress awareness: Learn to recognize your body's stress signals early • Relaxation training: Develop the ability to actively calm your nervous system • Anxiety management: Reduce physiological arousal through real-time feedback • Mindfulness enhancement: Deepen your mind-body connection In clinical settings, EDA/GSR biofeedback is a preferred method for teaching relaxation and stress regulation. With the eSense Skin Response, you bring this proven technique into your own home. The free app includes detailed introductions and guided exercises to help you get started—no prior experience required.
Most modern iOS devices need a 3.5mm audio adapter:

Most Android devices with USB-C need a USB-C to 3.5mm audio adapter.
Available as optional add-on in our shop (+€10).
The free eSense App offers everything you need for effective biofeedback training: real-time measurement display, guided exercises, customizable training programs, and comprehensive session analytics. Export your data as CSV for detailed analysis. Optional premium features and subscriptions available for advanced users.
The eSense Skin Response measures electrodermal activity (EDA/GSR) — your body's immediate response to stress and emotional arousal. It's the foundation of our biofeedback ecosystem and can be expanded with additional sensors.
Expand your Skin Response training:
• Add Respiration: The eSense Respiration breathing belt connects directly to your Skin Response for combined EDA + breathing feedback
• Add Pulse (Bluetooth): Monitor HRV alongside skin conductance for comprehensive autonomic nervous system insight
• Triple Combo: Skin Response + Respiration + Pulse gives you the complete stress response picture
Each eSense sensor is designed to work standalone or together. See all combination possibilities →
