Clinical-grade photoplethysmography sensors in a band you'll forget you're wearing. Heart rhythm, blood oxygen, sleep architecture — measured with accuracy validated in peer-reviewed research.
Every sensor calibrated against clinical-grade equipment. Every algorithm informed by published research.
24/7 optical heart rate monitoring with dual-wavelength photoplethysmography. Per-second sampling captures resting, active, and recovery states with clinical precision.
± 1.5 BPM vs ECG referenceReflectance-mode pulse oximetry with red and infrared LEDs. Analyzes hemoglobin light absorption to estimate peripheral arterial oxygen saturation continuously.
≤ 4% RMSD from medical referenceBeat-to-beat interval analysis reveals your autonomic nervous system balance. Low HRV is a recognized independent predictor of coronary heart disease and mortality risk.
RMSSD · clinical-grade accuracyMulti-sensor fusion of PPG, accelerometry, and skin temperature classifies Light, Deep, and REM stages. Combined-sensor approaches achieve up to 79% agreement with polysomnography.
4-stage classificationHRV-derived stress scoring quantifies your autonomic load throughout the day. Real-time readiness scores help you balance exertion and recovery for optimal performance.
Real-time readiness indexMulti-axis accelerometer tracks steps, distance, and caloric expenditure. Estimated VO2 max provides an objective measure of cardiovascular fitness and aerobic capacity.
GPS-enhanced trackingOceaNova uses reflectance photoplethysmography — the same core technology validated across hundreds of peer-reviewed studies. Green and infrared LEDs emit light into the wrist, where sensors measure volumetric changes in blood vessels with each cardiac cycle.
Clinical research confirms that modern wearable PPG sensors can detect reduced blood oxygen states with root-mean-square deviation under 4% compared to medical-grade pulse oximeters — meeting the requirements of ISO 80601-2-61.
For sleep staging, we combine PPG-derived heart rate variability with accelerometer motion data and skin temperature — an approach shown to boost classification accuracy by 16% over motion-only methods in validated studies.
Titanium-alloy band weighing 28g sits comfortably 24/7. IP68 water resistance to 50 meters means it handles the ocean, the shower, and the boardroom. Sensors auto-calibrate to your wrist within 30 seconds.
Every second, dual PPG sensors capture your cardiac rhythm. Every night, multi-sensor fusion maps sleep architecture across four stages. All biometric data encrypted on-device until you choose to sync.
The OceaNova app translates raw biometric signals into actionable health intelligence — daily readiness scores, longitudinal trend analysis, and exportable physician reports. Your data, your control.
