Hi Product Hunt! 👋 I was frustrated that getting a daily recovery score required Whoop ($30/mo) or Oura ($6/mo) — when my Apple Watch already collects all the data needed. So I built HRV Flow. It turns your wake-up HRV, resting heart rate, and sleep duration into a single 0-100 score every morning. Three things that make it different: 1. SCORE INSIGHTS — Not just a number. The app shows you why...
HRV FlowFree daily condition score for Apple Watch — and your iPhone
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.
