WatchBarometer turns air pressure into useful context on iPhone and Apple Watch. Highlights: - current sensor pressure or sea-level-normalized pressure - short-term weather trend from pressure changes - pressure history from six hours to the complete timeline - comparison of raw and altitude-aware sea-level pressure - GPS altitude history with optional barometer refinement - focused measurement sessions - widgets, Live Activity, and Apple Watch complications WatchBarometer uses the device's running barometer stream, GPS altitude for sea-level context, and read-only HealthKit samples only when Apple already includes barometric pressure metadata. Important: - high- and low-pressure classifications use compensated sea-level pressure only - raw sensor pressure is not misleadingly classified across different elevations Built for weather watchers, hikers, and anyone who wants to understand pressure, trend, and altitude instead of seeing just one number.
