Air Mass is the derived-meteorology lab card: dew point spread, estimated cloud base, heat index or windchill (whichever applies), all computed on-watch from temperature, humidity, and wind. Settings let you recolor the accent, toggle wrist-raise seconds, and switch Clean, Standard, or Dense layouts — changes apply instantly, no restart needed.

Features:
- Signature look: the derived-meteorology lab card
- Shows steps, heart rate, weather, and watch battery
- Burn-in-safe AMOLED always-on layout
- Live settings: accent color, seconds, density
- Clean/Standard/Dense density modes
