HRV Watch: Readiness Score

Scientific HRV Recovery Trends

Free · In-App Purchases · Designed for iPad. Not verified for macOS.

Improve your well-being with simple HRV and RHR insights. Track stress, recovery trends and readiness directly from your Apple Watch. Heart Rate Variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats, measured by the variation in the beat-to-beat interval. HRV reflects your body’s ability to adapt to stress and maintain balance. This app provides an in-depth analysis of HRV SDNN values, as well as key metrics like Resting Heart Rate (RHR), HRV Readiness Score, and Recovery Ratio, recorded by your Apple Watch. What is HRV? HRV describes your body’s ability to adapt the frequency of your heart rhythm to meet current demands. A healthy individual constantly adjusts their heart rhythm, reflecting resilience and adaptability. Regular tracking of HRV, RHR, and related metrics can provide useful context on stress and recovery trends. Key Features: - HRV Analysis: View your HRV SDNN values, providing insights into your physiological state. - RHR Monitoring: Track your Resting Heart Rate as an important personal context metric for recovery. - HRV Readiness Score: Assess daily readiness with a relative 0-100 signal based on your personal HRV and RHR trends (around 50 reflects baseline). - Recovery Ratio: Understand recovery relative to your own baseline (around 1.0 reflects baseline). - Mindful filter: Separate HRV values taken during a mindful session from all other readings to spot the cleaner, more comparable trend. Data Integration: The app seamlessly connects with Apple’s Health app to display your recorded data on: Apple Watch: A dedicated app and complication for quick insights. iPhone: A user-friendly interface to analyze trends and progress. How to Use: Compatibility: The app requires an Apple Watch Series 3 or later. Recording HRV Data: Use the Apple Breath App or other mindfulness apps to measure HRV values. Consistency Matters: For accurate trends, measure HRV, RHR, and Recovery Ratio consistently in similar conditions, such as "first thing in the morning" before starting your day. Best practice: do a short mindful session right after waking to collect a reliable HRV baseline and use the mindful/non-mindful filter to compare. This app utilizes advanced AI technology to provide context-aware coaching tailored to you. This app uses artificial intelligence with OpenAI to analyze your data. These metrics are informational trend tools and are not intended to diagnose medical conditions. Medical disclaimer: HRV Watch does not provide medical diagnosis or treatment. Always seek advice from a physician or other qualified healthcare professional in addition to using this app and before making medical decisions.

Ratings & Reviews

  • This app has not received enough ratings or reviews to display an overview.

This update improves scientific consistency and chart readability: - RHR chart redesign: baseline band (P25-P75), dynamic y-axis, clearer legend, plus markers for above/below baseline band and outliers. - More robust readiness/recovery scoring based on personal baselines: readiness is a relative 0-100 signal (around 50 = baseline), recovery ratio is centered around 1.0. - Better baseline quality handling: mindful-aware baseline selection and neutral fallback when history is too sparse. - AI feedback prompts were tightened to be clearer, data-bound, and evidence-aware.
