Replace “I'm just tired”
With objective health trends.
Stop trying to summarize weeks of fatigue in a ten-minute appointment. Purple transforms your Apple Health data into a professional-grade biometric report, so you can lead more informed conversations with your wellness provider.
Closing the Gap.
The gap between how you feel and what standard tests show is where you lose your mind. We close that gap by exposing long-term variability trends.
Systemic fatigue detected. HRV deviation is 22% below baseline for 14 days.
Export this telemetry. The data clearly indicates chronic stress buildup.
The Root Cause:
Autonomic Misalignment
When you force an aggressive social schedule against your genetic chronotype, you don't just get tired. You trigger a perpetual sympathetic nervous system response.
Social Jetlag
When your schedule fights your DNA, your system suffers chronic oxidative stress. Purple calculates the exact offset.
HRV Decay
Your Heart Rate Variability doesn't lie. Shifting sleep patterns crashes your HRV, signaling urgent recovery needs.
Core Sleep Deficit
Duration is a myth. Timing is everything. Stop chasing 8 hours and start optimizing your Core Sleep windows.
