Data Accuracy

 

Scientifically Validated

1. Proven Precision, Backed by a Decade of Expertise

Nova's health algorithm are built on over 10 years of rigorous development and validation in the smart wearables industry. Every data point Nova captures is backed by years of R&D, countless iterations, and real-world validation, delivering consistently accurate and reliable body data that meets professional-grade standards.

Behind every simple-looking number is thousands of hours of algorithm development at Nova. From clinical-grade validation to real-world simulations and diverse user testing, every data point is carefully refined.

2. You See the Numbers — We See the Process

Sleep tracking

Sleep tracking

Sleep tracking is benchmarked against polysomnography (PSG)—which monitors EEG, EOG, and EMG signals—based on data from over 400 participants, including those with destructive sleep apnea (OSA). Key sleep metrics such as onset, wake time, and all four sleep stages are rigorously compared to ensure accuracy.

Step tracking

Step tracking

Step tracking is tested against varied real-life scenarios, from intended movements like walking, running and stair climbing to false trigger scenarios like typing, driving, or scrolling on a phone. Multiple testing modes (100 steps, 500 steps, 30 minutes) were used across a diverse group of participants. This comprehensive approach ensures Nova delivers highly accurate and reliable step counting in everyday life.

Heart rate monitoring

Heart rate monitoring

Heart rate monitoring is validated against ECG chest straps with over 98% accuracy. Both static (e.g., relaxed hand, light finger movement) and dynamic (e.g., walking, running, transition states) scenarios are tested across different skin tones, ages, and genders to ensure consistent performance.

Calorie tracking

Calorie tracking

Calorie tracking uses a metabolic gas analyzer—the clinical gold standard—to assess energy expenditure during activities like running, cycling, and elliptical workouts. Data from over 100 participants confirms accurate results across everyday conditions.

3. Built for Everyday Confidence

At Nova, accuracy isn't an afterthought—it's the foundation. From lab-grade comparisons to daily life validation, Nova's algorithms deliver true-to-life health insights—so you can wear it 24/7 and trust every number.

Recovery Algorithm

Recovery Score Image

The human body is constantly in flux—each subtle change offers valuable insight into your overall well-being. When you're well-rested, you're energized and ready to take on challenges. When you're fatigued, your body needs rest and recovery. Yet these signals are not always easy to perceive. Nova's Recovery feature makes your readiness visible, delivering a precise daily score (0–100) that reflects your recovery status — higher scores indicate better recovery capacity.



Recovery Score Image

This score is powered by the integration of key physiological signals, including heart rate variability (HRV), resting heart rate, sleep quality, and blood oxygen levels.

 

Users can observe how daily habits impact recovery and receive personalized guidance—such as prompts to reduce training intensity when recovery is low—helping to manage stress, improve sleep, and maintain a healthy balance between exertion and rest.


Recovery Score Image

Built on advanced high-frequency sensors and adaptive algorithms, Nova's recovery system continuously captures key biometric signals and dynamically adjusts the weighting of each metric based on user-specific data.

 

HRV quantifies autonomic nervous system activity via beat-to-beat variation, while sleep performance is assessed through movement and heart rate patterns. This multi-layered data is fused into a real-time score and trend prediction, offering actionable insights to optimize your daily performance and long-term health.


At its core, Nova's recovery algorithm was developed with one goal:

to serve real user needs. It's not just about data—it's about helping people make smarter, more informed decisions to feel better, perform better, and live better.

Precision Engineering at the Core

Miniaturization Meets Mastery

  • Nova's engineering combines advanced miniaturization with uncompromised performance. High-density chip integration and a 4-layer stacked FPC enable complex signal processing within a minimal footprint, while precision CNC machining shapes the titanium casing to just 0.2mm for a lightweight yet durable build.

  • Proprietary signal optimization algorithms ensure stable wireless performance—even within a metal enclosure—by enhancing antenna efficiency.

  • Pair text with an image to focus on your chosen product, collection, or blog post. Add details on availability, style, or even provide a review.

  • Proven Hardware Expertise

    Backed by years of experience in smart wearable development and a robust supply chain, Nova has a strong foundation in high-precision hardware manufacturing. This ensures not only performance and quality, but also reliable mass production capabilities.

  • Compact Yet Powerful

    From structure to signal, every element of Nova is optimized for comfort, durability, and precision. It's not just a smart ring—it's a wearable engineered to disappear on your finger while delivering consistent performance.
