WatchBarometer

WatchBarometer is a pressure-first barometer for iPhone and Apple Watch. The app turns raw sensor pressure into something you can actually read: - current pressure as a direct sensor value or compensated to sea level - short-term weather reading from pressure change - pressure history across short and long ranges - altitude timeline from GPS, with optional barometer refinement between anchor points That is the core message of WatchBarometer: Pressure alone is not enough. Trend, sea-level context, and altitude are what make a barometer useful. Highlights: - live pressure on iPhone and Apple Watch - direct Sensor / NN switch for the current reading - history from 6h to All - compare raw pressure and altitude-aware sea-level pressure - low, normal, and high pressure zones based on NN pressure - altitude timeline with GPS only or GPS + Baro - focused sessions for dedicated measurements - widgets, Live Activity, and watch complications WatchBarometer builds its history from two sources: - the device's running barometer stream - HealthKit samples that already include barometric pressure metadata The app is read-only with HealthKit. It does not interpret oxygen saturation medically. It only uses samples when Apple already includes barometric pressure metadata in the sample itself. Important: - absolute low-pressure and high-pressure classification is based only on compensated sea-level pressure - raw sensor pressure is not mislabeled across different elevations WatchBarometer is for people who want to understand pressure, not just see a number: weather watchers, hikers, altitude nerds, and anyone who wants a clear read on trend and height.
