HRV Flow

¿Qué es HRV Flow?

A free daily condition score for Apple Watch — no extra wearables, no subscriptions. HRV Flow turns your wake-up HRV, resting heart rate, and sleep into a 0-100 score every morning. Score insights tell you what changed: "Wake-up HRV was low" or "Sleep was short." Score low? Try a 1-minute breathing exercise on Watch or iPhone. Watch your heart rate drop from 82 to 68 bpm. Score → Breathe → See the change. 11 breathing patterns, recommended by time of day. All data stays on your device.
