Pascal Barometer vs Air Barometer

Track atmospheric pressure and predict weather changes using your device's built-in barometer. Pascal transforms your iPhone and Apple Watch into precision barometric instruments. Monitor pressure trends, receive storm warnings, and get weather predictions — all computed on-device with no internet required. FEATURES • Real-time pressure monitoring with 12-hour trend charts • On-device weather forecasting using the Zambretti algorithm • Storm alerts via push notifications • Live Activities showing pressure on Lock Screen and Dynamic Island • Flight mode with cabin altitude tracking • iOS widgets (small, medium, large) and Apple Watch complications • Hybrid calibration system for accurate readings PRIVACY FIRST All data stays on your device. No accounts, no cloud sync, no tracking. Location is used only for GPS altitude calibration and is never stored. TECHNICAL Pascal uses Apple's Core Motion framework to access the barometric sensor, delivering sub-Pascal resolution. The hybrid calibration system combines GPS altitude with relative altitude tracking to filter out elevation changes and surface true weather signals.

Barometer is a modern atmospheric pressure app designed for people who want more than just basic weather information. Unlike most barometer apps that only display sea level pressure, this app can also show the actual atmospheric pressure at your current altitude. This makes the app closer to a real physical barometer and helps you better understand real local conditions. The app also provides clear pressure charts, allowing you to track changes throughout the day and monitor long-term pressure trends. Perfect for: • fishing and outdoor activities; • weather-sensitive people; • hiking and camping; • monitoring weather changes; • anyone interested in atmospheric pressure. Features: • relative pressure at sea level; • actual pressure at local altitude; • pressure in hPa/mmHg/inHg; • hourly pressure chart; • daily history and forecast chart; • current temperature and humidity; • clean and easy-to-read interface; • support for multiple locations. Whether you are planning a fishing trip, checking changing weather conditions, or simply curious about atmospheric pressure, Barometer gives you accurate and easy-to-understand information in a beautiful interface.
