Connected to Apple Health and Google Health Connect. Your recovery score shapes every AI response, every tone suggestion, every piece of guidance Rev gives you.
A composite daily score from 0 to 100 calculated from your sleep quality, HRV, resting heart rate, and recent activity. Displayed prominently on your Rev home screen every morning. When your score is below 40, Rev automatically uses a gentler, shorter, more understanding tone in all AI features. When it is above 80, Rev is more energetic, ambitious, and bold.
HRV is the most scientifically validated marker of nervous system recovery. Rev reads your HRV from Apple Health or Health Connect and uses it as the primary input to your recovery score. Low HRV signals fatigue. High HRV signals readiness. Rev responds accordingly.
Total sleep hours, sleep efficiency, and time in deep sleep are read from your wearable or iPhone. Rev uses sleep quality to flag when you may be making communication decisions you will regret — and suggests reconsidering before sending.
The Depression, Anxiety, and Stress Scale-21 is a validated clinical instrument used worldwide. Rev includes a weekly DASS-21 check-in. Results are stored on-device only, never transmitted. Rev uses your DASS-21 score to contextualise your communication patterns over time.
Rev monitors the emotional tone of your ongoing conversations with key contacts over time. Tracks average warmth, frequency of conflict language, and response latency patterns. Flags conversations where the health score has declined, and suggests check-in messages.
Daily step count, active minutes, and exercise type are pulled from Health Connect and Apple Health. High activity days signal energy and confidence. Rev adjusts the assertiveness of suggested replies accordingly.
Every health metric is read, processed, and stored entirely on your device. No health data is ever transmitted to our servers or any third party.
Your recovery score shapes Rev's behaviour through a local logic layer. The actual health values are never included in any AI prompt sent to cloud services.
All health data processed by Rev is cleared when you reset your profile in Settings. Nothing persists in the cloud because nothing is ever sent there.
