Biofeedback training with the Mindfield eSense sensors: measure stress, train relaxation, guide your breathing, monitor HRV and muscle activity - live on your iPhone/iPad
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

With precise sensors, a versatile app and cloud functions, biofeedback integrates seamlessly into daily life, training and research.
Love the HRV training program. Have found it very beneficial for dealing with my stress and teaching others to deal with theirs.
Delighted to the new HRV sensor

I’ve used the Temperature and SkinConductance sensors with great success and am delighted to see the new HRV ( chest belt ) sensor arrive. I used it straight out of the box with no problems and got exactly the same sense of relaxation that I get from other HRV devices. App works well, and the equipment is very well priced. The statistics are professional level. Obviously there is some fine tuning to be done, but great so far. Once the respiration sensor arrives it will be a formidable set of equipment.
Needs some input from a designer

I am a biofeedback practitioner and recommended this app and its sensor regularly to my clients for home practice. It has been especially useful during the pandemic. I find the visual feedback to be very helpful. However, the audio feedback is poor, and the app feels clunky overall. Frankly, I can tell it was designed by engineers. Some work with a designer who can make it more appealing to the masses would be helpful. This is a great product, but it just needs some extra care.
Ok

Not bad but not great. For example:The sensors are a bit temperamental. Maybe add a sensor test function that doesn’t push data to Health? Otherwise a few seconds of lost contact adds dozens of useless rows of data. Thanks.
New in 8.0.6
- Brand-new technical foundation: full migration to Capacitor 7. Significantly improved stability, a cleaner user interface and a platform for faster future updates.
- NEW: Lab Streaming Layer (LSL) is now included in the OSC In-App Purchase. Stream your eSense data in real time to LabRecorder, OpenViBE, MATLAB, BCI2000, pylsl and any other LSL-compatible research tool.
- NEW: Archive wipe. Supervisors can reset a client's data from the profile page. Every user can also wipe their own data per sensor via the 3-dot menu in the archive - ideal for shared devices and multi-user setups.
- NEW: Sensor connection check. When you start a training without a connected sensor, the app now shows a clear message and points you to Demo Mode.
- Reworked procedure system: downloads, uploads, sharing and the local procedures list all work reliably now.
- Philips Hue: pairing without the 10-second button press. eSense Pulse, breath pacer and Hue lighting now share a consistent color and brightness logic. Improved temperature slider (20-40 °C in 0.1° steps) is available in Open Training and Procedures.
- Breath pacer: hold times applied correctly with clearly highlighted breaths-per-minute. Oscilloscope: scale lock now also in fullscreen and procedures. Real-time thresholds during video feedback (sharpness, brightness, color).
- Archive: reliable ZIP export, clearer sort toggle and more control over cloud sync (no forced sync after login).
- Many further refinements: tactile feedback, restored YouTube thumbnails, fixed Help links, refreshed Shop & Plans, login language selection and UI polish across headers, modals and notch handling.
