Pascal turns your iPhone's built-in barometer into a precision pressure instrument. It shows what the air is actually doing, measured on your phone, with no internet required. READ THE TREND See whether pressure is steady, rising or falling, and how fast, using the same 3-hour bands meteorologists use. Falling pressure usually comes before unsettled weather, rising pressure before settled weather. Pascal tells you what it measures, not guesses. ALERTS ON YOUR TERMS • Storm alerts when pressure drops at storm rates • Pressure swing alerts when pressure rises or falls 4, 6 or 8 hPa within 12 hours, with a 60-day swing log • Daily limits and sensitivity you control HISTORY AND ALTITUDE • Pressure and altitude charts over 12 hours, 48 hours or 7 days • Total climb and descent for walks, hikes and drives • Cabin altitude tracking on flights EVERYWHERE YOU LOOK • Home Screen widgets, Lock Screen and Dynamic Island Live Activities • Apple Watch app and complications • Built for iPhone Duo: a full instrument panel unfolded, and the complete app on the front screen ACCURATE BY DESIGN Pascal reduces pressure to sea level using your altitude, and checks every GPS altitude against the barometer itself, so changing height or a bad GPS fix never throws your readings off. WORKS OFFLINE, PRIVATE BY DESIGN No internet, no account, no cloud. Everything is measured and stored on your phone. Location is used only to work out your altitude and is never stored or shared. Pascal reports measured pressure changes. It is not a weather forecast or medical advice.

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.
