Built for High Intensity Performance
Advanced ECG measurement, R-R interval tracking, and a 9-axis motion sensor work together to deliver clean, reliable data even during high-intensity training.
With precise acceleration, gyroscope, and magnetometer sensing, plus Bluetooth® heart rate services and optional single-channel ECG, you get deeper insights, smarter analysis, and confidence in every beat.
Training Readiness
Netrin’s 2-minute Training Readiness Test helps you understand how ready your body is to perform. Taken in a relaxed, supine position, it measures key cardiac recovery markers to guide smarter training decisions—so you know when to push and when to recover
​
​Using advanced ECG-based insights, the test analyzes:

Heart Rate
Variability (HRV)
to assess recovery, stress levels, and nervous system balance.
Resting Heart Rate (RHR)
to gauge daily readiness and overall cardiovascular recovery.
HRV trends
to track long-term adaptation, training load, and performance progress.
The Checkpoint Test
Netrin’s Checkpoint Test transforms fitness assessment into an engaging, 10-minute cardiovascular challenge. This guided experience delivers powerful insights into heart health and endurance, helping you understand where you stand and how to improve.​

By tracking progress over time, the Checkpoint Test measures cardiovascular efficiency, recovery, and training impact, supporting long-term performance gains and improved heart health. Every session unlocks insights into:
1. VOâ‚‚ Max,
​powered by the Netrin Heart Score (NHS)
3. Heart Rate Zone Distribution
showing time spent at different intensity level.
2. Recovery Beats (HRR60)
measuring how quickly your heart recovers after exertion.
4. Movement Load vs. Heart Rate Zones

Beyond tracking, Netrin turns every session into meaningful data. Each activity is automatically analyzed to help you understand intensity, effort, and consistency so you can train smarter without changing how you move. Each session delivers insights into:
1. Average Heart Rate
The average heart rate recorded during a workout, reflecting overall exercise intensity.
3. Training Load
​The total physiological stress accumulated from exercise, combining intensity and duration to reflect overall strain.
5. Cardio Adherence
Tracks how consistently you train within coach-prescribed heart rate zones across workouts.
2. Zone Distribution
The percentage and duration of time spent in each heart rate zone across a session.
4. Audio & Visual Alerts
Real-time cues that guide cardio intensity and recovery, plus guided strength sessions with on-screen demos for proper form.
6. Movement Load vs.
HR Zone Correlation
Reveals how physical effort aligns with cardiovascular response across intensity levels.
Built for Customization & Growth
With onboard data logging memory, the Netrin ECG Sensor is designed to do more than just track. Developer tools and software libraries make it easy to build custom applications and integrate with mobile platforms, while wireless firmware updates ensure the sensor evolves with new features and improvements over time.
