SleepViz

See what's happening while you sleep

What it does

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.

Homebrew 6.0.0▲1,481
Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
