Resting test
Sit still, connect your sensor, and build a personal baseline over three mornings.
Morning readiness
A 2-minute check before training.
Most HRV apps bury you in numbers. BioResonance starts with the decision you actually need: is today a day to push, maintain, or recover?
Known HRV metrics
Track heart rate, RMSSD, SDNN-style session values, signal quality, PNS/SNS balance, and stress index.
No generic score
Readiness compares against your own recent history so the signal stays personal and practical.
Resonance training
Follow the pacer. Watch your HRV respond.
Use a guided breathing pacer and live HRV feedback to discover the breathing rate that creates the strongest, most stable heart-rate oscillation for you.
- Adjustable breathing rate
- Live coherence and signal quality
- Session history for progress
- Designed for calm, low-distraction training
