The Mindfield eSense App turns your iPhone and iPad, together with the eSense Biofeedback sensors, into a comprehensive solution for stress measurement, relaxation training and self-awareness - in daily life, in training and coaching settings, and in research.
**What is Biofeedback?**
Biofeedback makes unconscious body signals such as skin conductance, skin temperature, pulse, breathing or muscle tension visible in real time. With targeted training you learn to influence these signals consciously - a scientifically well-documented approach for stress reduction and overall wellbeing.
**Five sensors for precise biofeedback:**
1. **eSense Skin Response**: measures skin conductance (EDA, GSR) as a direct stress indicator.
2. **eSense Temperature**: captures skin temperature for effective hand-warming training.
3. **eSense Pulse**: Bluetooth chest strap for accurate heart rate and heart rate variability (HRV) measurement.
4. **eSense Respiration**: breathing-belt add-on for the eSense Skin Response - captures breathing rate, depth and pattern.
5. **eSense Muscle**: measures muscle activity (EMG) for targeted relaxation and activation training.
**Comprehensive app features:**
- **Customisable breathing pacer** with breathing rate, hold times and resonance breathing
- **Multimedia feedback** through video, music, sounds, vibration and Philips Hue Smart Bulbs
- **Adjustable training programs (procedures)** for structured multi-step sessions
- **Unlimited archive** with ZIP export, CSV/PDF data analysis and per-sensor data wipe for shared devices
- **Real-time thresholds** for reactive video feedback (sharpness, brightness, colour)
- **14 languages**, continuous updates, intuitive operation
**Concrete use cases:**
- Stress management and more recovery in everyday life
- HRV training and resonance breathing for autonomic balance
- Breathing exercises for mindfulness, sports and mental clarity
- Hand-warming training to support circulation
- Muscle relaxation for desk-bound tension
- Focus and performance training
**Cloud functions and eSense Web App:**
- **Basic Plan**: cloud storage of measurements and access to the eSense Web App (esense.live)
- **Premium Plan**: additional cloud storage of procedures, real-time streaming to the Web App and sharing of measurements
- **Web App**: simultaneous display of multiple sensors - ideal for group supervision and professional use
**OSC and LSL streaming (In-App Purchase, optional):**
For researchers and power users: stream your eSense data in real time directly from the app.
- **OSC (Open Sound Control)**: to receivers like Max/MSP, Pure Data, TouchDesigner, Processing
- **LSL (Lab Streaming Layer)**: to LabRecorder, OpenViBE, MATLAB, BCI2000, pylsl and other LSL-compatible research tools
Both protocols are bundled into a single In-App Purchase.
**Who is the app for?**
- **Individuals** who want to train stress, breathing and relaxation in a focused way
- **Trainers and coaches** for structured training sessions, with a multi-user-friendly archive on shared devices
- **Researchers and universities** for quantitative data collection with bridges to MATLAB, LabRecorder and custom LSL pipelines
**Flexibility and mobility:**
- Use at home, in a training or coaching setting, or on the go with iPhone or iPad
- Integration into daily life for regular biofeedback training
- Free app with continuous updates and fair value for high-precision biofeedback hardware
