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.

Verdict
The clearest difference is ads: Pascal Barometer at none against Professional Barometer's shown. Pascal Barometer also leads on update cadence (every 6 days vs every 42 months). Professional Barometer's advantage is review sentiment (45% vs 25%) and monetization model (ad-supported vs free with in-app purchases). On price, rating, in-app purchases and device support there is nothing between them.
