Healthy Weather

What it does

Healthy Weather tells you exactly when the sun is worth stepping outside for — and when it isn't. Most weather apps stop at UV index. We go further: a science-backed model that calculates your personal vitamin D synthesis based on your skin type, age, cloud cover, and local air quality. No more guessing if 15 minutes at 3pm in November actually does anything. Built for people who'd rather get their D from the sky than a pill.

  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!
