GlobalAlert vs Pascal Barometer

GlobalAlert helps you monitor natural disasters and major natural events around the world. Track earthquakes, wildfires, volcanoes, storms, floods, ice events, dust and haze events, landslides, and other active events from one app. View live activity on an interactive Apple Maps experience with earthquake markers, natural disaster icons, grouped event markers, tectonic plate boundaries, and a globe-style map view. Zoom out for a global overview or zoom in for more detail. GlobalAlert also includes local notifications, Home Screen widgets, Apple Watch support, detailed event pages, search, filters, and useful stats. Features: • Live earthquake tracking • Natural disaster monitoring • Wildfire, volcano, storm, flood, ice, dust, haze, and landslide events • Interactive global map • Apple Maps globe-style view • Tectonic plate boundaries • Grouped map markers for crowded areas • Built-in map legend • Earthquake magnitude, depth, time, location, and tsunami-related details • Search and filters • Event stats and category breakdowns • Local notifications • Home Screen widgets • Apple Watch app • iPhone, iPad, and Mac support GlobalAlert is designed for awareness and visualization. For emergency decisions, always follow official alerts, emergency services, local authorities, and government guidance. Powered by USGS All data is provided by the United States Geological Survey (USGS) for maximum accuracy and reliability.

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.
