How Heart Rate Variability (HRV) Affects Work Performance
Learn why HRV is the ultimate metric for measuring stress and focus, and how FlowCrest uses it to build a smarter schedule.
HRV: The Window into Your Nervous System
Heart Rate Variability (HRV) is a powerful indicator of your autonomic nervous system's balance. A higher HRV generally correlates with better cognitive performance and emotional resilience, making it the perfect metric for productivity planning.
Measuring Stress and Recovery
FlowCrest integrates with HealthKit to analyze your HRV trends. If your HRV is low, it's a sign that your body is under stress or hasn't fully recovered. The app automatically adjusts your schedule to prioritize recovery or lighter tasks until your readiness improves.
Optimizing Deep Work Windows
Deep work requires significant cognitive resources. By identifying the times of day when your HRV and energy levels are most stable, FlowCrest helps you protect your most valuable hours for your most important projects.
