SleepViz - See what's happening while you sleep

by•
SleepViz records and analyzes sounds while you sleep — snoring, breathing, disturbances — and turns them into a clear visual sleep report. It reads your Apple Health data (sleep stages, heart rate, HRV, SpO₂) to give you full context around each night. Everything stays on your iPhone. No account, no cloud, no subscription. Just open the app, start a session, and wake up to a full breakdown of your night.

Hey PH! 👋 I built SleepViz because I wanted to actually understand my sleep — not just a score, but what's happening sound-wise throughout the night. It records audio while you sleep, detects events, and combines that with your Apple Health data (heart rate, HRV, sleep stages) into one report. 100% on-device. No login, no server, no subscription. Would love your honest feedback — especially if you've tried other sleep apps. What's missing for you?
