The Mindfield eSense App for all eSense Sensors
The free eSense App is available for Android smartphones and tablets on the Google Play Store, and for iPhone and iPad on the Apple App Store. The app offers comprehensive features for effective biofeedback training including measurement display (bargraph and oscilloscope), feedback via video, music, tones, vibration, and smart bulb lighting. Optional premium features are available through in-app purchases.
HRV Biofeedback with the eSense Pulse
The Mindfield eSense Pulse is a portable HRV biofeedback sensor that connects wirelessly to your smartphone or tablet via Bluetooth. Using medical-grade 1-channel ECG technology with a comfortable chest strap, it delivers accurate heart rate variability measurements for effective stress management training. Heart rate variability reflects your autonomic nervous system's balance between stress and relaxation. Through real-time biofeedback—including visual graphs, audio cues, and video feedback—you learn to actively influence your HRV and reduce stress levels naturally. The free eSense App provides comprehensive training programs, detailed HRV statistics with time-domain and frequency-domain analysis, and seamless data export as CSV or PDF reports. Combine with the optional eSense Respiration sensor to synchronize breathing exercises with your HRV training for enhanced results.

Frequently Asked Questions
How does HRV biofeedback work?
HRV biofeedback measures the variation in time between heartbeats (R-R intervals) using an ECG sensor. The eSense Pulse uses a medical-grade 500 Hz ECG to capture this data in real-time and sends it to your smartphone via Bluetooth. The free eSense App then provides visual and audio feedback, helping you learn to consciously influence your heart rate variability through breathing techniques and relaxation exercises.
Can I do biofeedback training at home without professional guidance?
Yes, the eSense Pulse is specifically designed for independent home training. The free app includes guided training programs for beginners as well as a customizable Open Training mode for advanced users. While professional biofeedback practitioners can also use the eSense Pulse in clinical settings, most users successfully train at home with the built-in programs and tutorials.
What is heart rate variability and why does it matter?
Heart rate variability (HRV) is the natural variation in time between consecutive heartbeats. A higher HRV is generally associated with better stress resilience, cardiovascular fitness, and autonomic nervous system balance. Research suggests that regular HRV biofeedback training can help improve stress management, emotional regulation, and overall well-being. The eSense Pulse measures key HRV metrics including SDNN, RMSSD, and pNN50.
How accurate is the eSense Pulse compared to medical ECG devices?
The eSense Pulse uses a medical-grade 1-channel ECG with a 500 Hz sampling rate, which provides clinical-level accuracy for R-R interval detection. While it is not a diagnostic medical device, its measurement precision is comparable to professional HRV monitoring systems. Data can be exported as CSV for analysis in professional software like Kubios HRV.
Do I need a subscription for the eSense App?
No, the core eSense App is completely free with no subscription required. You get unlimited training sessions, multiple user profiles, CSV data export, and comprehensive HRV analysis at no extra cost. Some optional premium features (additional training programs and biofeedback modes) are available through one-time in-app purchases.
How long should an HRV biofeedback training session last?
A typical HRV biofeedback session lasts 10 to 20 minutes. Beginners often start with shorter 5-10 minute sessions and gradually increase duration. For best results, consistent daily training of 10-15 minutes is recommended. The eSense App tracks your progress over time so you can see improvements in your HRV metrics across sessions.
Mindfield eSense Product Comparison
The eSense Pulse measures your heart rate variability (HRV) — a key indicator of stress resilience and autonomic balance. Because it connects via Bluetooth, you can easily combine it with other eSense sensors that use the 3.5mm audio jack.
Popular combinations with eSense Pulse:
• Pulse + Skin Response: Monitor both HRV and electrodermal activity for comprehensive stress feedback
• Pulse + Temperature: Combine heart coherence training with peripheral blood flow awareness
• Pulse + Skin Response + Respiration: The ultimate trio for coherence breathing synchronized with HRV
