Your Nervous System. Decoded.
Research-Grade, From Your Wrist.
60+ metrics across 9 physiological categories – computed from your existing wearable. Garmin, Wahoo, or Polar. No lab required. Just your heartbeat.
The Problem
Your watch shows a number. You deserve an answer.
Most wearable apps reduce HRV to a single daily score or a traffic-light readiness indicator. That’s like judging an entire symphony by its volume.
- A single HRV score hides whether your autonomic balance is shifting.
- Readiness widgets cannot detect ventilatory thresholds or fractal dynamics.
- Without baseline tracking, you cannot tell normal variation from real change.
The Solution
obseed HRV Analytics
obseed takes the raw RR-interval data your wearable already records and runs a research-grade analysis pipeline across 9 physiological domains. Time-domain, frequency-domain, nonlinear dynamics, recurrence quantification, multiscale entropy, and exercise physiology metrics – all computed automatically with transparent quality validation.
What you get
9 Analysis Categories
Time-domain, frequency-domain, nonlinear, geometric, PRSA, respiratory, recurrence, multiscale entropy, and exercise physiology.
Personal Baseline Tracking
30-day rolling baseline with z-scores and percentile badges. See exactly where each session stands relative to your norm.
Automatic Data Quality
Every analysis classified as high, moderate, or low validity. Transparent preprocessing shows exactly what was corrected.
15-Page Research Reports
Printable PDF reports with 8 chart types for your coach, doctor, or personal archive.
The difference
Same heartbeat. Different depth.
See what a research-grade analysis reveals compared to a consumer wearable score.
Without HRV Analytics
- One number, zero insight Your watch shows HRV: 45ms. Is that good? Bad? For you? Today? No context, no depth.
- Training zones from formulas Threshold estimates based on age and max HR. Your physiology is not a formula.
- No quality checks Wrist PPG error jumps from 0.49% at rest to 26.83% while cycling (PMC, 2025). Artifacts and ectopic beats? Silently averaged into your score.
With obseed HRV Analytics
- 60+ metrics, full picture RMSSD, SDNN, DFA alpha-1, Poincaré scatter, LF/HF ratio, Sample Entropy – each telling a different story about your autonomic state.
- Threshold exploration via DFA alpha-1 DFA alpha-1 crossover analysis surfaces early indicators of where your VT1 and VT2 may lie. An experimental research lens on your field data.
- Transparent validation Every beat classified. Ectopic correction documented. Validity tier assigned based on signal source (chest strap: 2.16% MAPE, wrist: 6.82%). You see exactly what was used and what was excluded.
8 visualizations
See what your heartbeat reveals.
Every HRV analysis generates 8 distinct chart types across your physiological domains. Each visualization answers a different question about your autonomic nervous system.
Poincaré Scatter Plot
See your beat-to-beat variability in two dimensions. The shape of the scatter reveals your autonomic balance.
RR-Interval Histogram
Distribution of your inter-beat intervals. Narrow means high stress, wide means recovered.
Frequency Spectrum
VLF, LF, HF power bands. Visualize the balance between sympathetic drive and parasympathetic recovery.
Multiscale Entropy
Complexity across 20 time scales. Healthy hearts are complex — rigidity signals trouble.
Recurrence Diagram
Detect hidden patterns and state transitions in your heart rhythm over time.
DFA Scaling Plot
Fractal analysis that can hint at where your ventilatory thresholds (VT1/VT2) may lie. Experimental.
Autonomic Balance Gauge
PNS and SNS indexes compared against your personal baseline. Ready to push, or time to rest?
Windowed Trends
RMSSD, SDNN, and DFA alpha-1 tracked across your activity with VT overlay markers.
From raw heartbeats to real decisions.
Your autonomic advantage.
obseed HRV Analytics doesn’t just analyze – it translates. Every metric is contextualized against your personal baseline, your daily tags, and your training load.
Training Readiness
Know When to Push, When to Rest
PNS and SNS indexes compared against your 30-day baseline tell you whether your autonomic nervous system is ready for intensity or needs recovery.
Threshold Exploration
Early Hints at Your Training Zones
DFA alpha-1 crossover analysis during your cycling or running sessions can surface early indicators of where your VT1 and VT2 thresholds may lie. An experimental research feature — not a lab replacement, but a starting point.
Context Matters
Correlate HRV With Your Life
Your daily tags (caffeine, sleep quality, medication, stress) appear alongside your HRV data. Finally see what actually moves the needle.
Personal Baseline
Track Your Autonomic Trends
30-day rolling baseline with percentile badges. See at a glance whether today's session is exceptional, normal, or concerning.
Data Quality
Trust the Numbers
Automatic validity classification (high, moderate, low) with transparent ectopic correction. You always know exactly what went into the analysis.
Your Wearable
No Special Hardware Required
Works with Garmin, Wahoo, and Polar — any device that records RR-intervals. Chest strap or wrist-based. Use the gear you already own.
Per-Session Detail
Understand Each Workout
Multi-session activities are broken down individually. See how your nervous system responded to each interval, each effort.

Share With Your Coach or Doctor
Generate 15-page printable PDF reports with all 8 chart types. Professional enough for a sports science lab, accessible enough for your training diary.
How it works
From Watch to Insight in 3 Steps
Step 1: Connect Your Wearable
Connect your Garmin, Wahoo, or Polar account to obseed. Your historical activities and RR-interval data sync automatically.
Step 2: Record a Session
Go for a ride or a run with your wearable. For best results, use a chest strap HRM. Wrist-based HRM is also supported – the validity tier will reflect sensor quality.
Step 3: Get Your Analysis
obseed automatically detects RR-interval data and runs the full 60+ metric analysis. View results in the app or download the PDF report.
The Kicker
Works retroactively, as always
HRV Analytics available immediately
Upload or sync your historical data. obseed analyzes any past activity that includes RR-interval recordings.
Your autonomic history, unlocked.
Not sure if your watch records RR-intervals?
Most Garmin, Wahoo, and Polar devices from the last 5 years do. Check our compatibility guide or reach out to us – we’re happy to help.
