WindScope,Learn Weather Charts vs Pascal Barometer

Stop guessing. Start understanding the weather. WindScope teaches you to read surface-pressure (isobar) charts the way professional sailors do — then lets you measure the wind yourself. Tap two isobars and instantly see the wind speed and direction from real meteorology (the geostrophic wind equation), with mean and gust, Beaufort force, and a sea-state guide. FREE, for everyone: • Live UK & North Atlantic surface-pressure charts (forecasts to 84 hours, colour + black/white) • Interactive wind measurement with a proper wind barb and an instrument readout • Beaufort scale, gusts, sea state, and kt / m·s / Bft units • “How It Works” guide and guided Practice Mode WINDSCOPE PRO — one-time unlock: • Every chart region, including Atlantic & Europe — covering Scandinavia, the Baltic and the Mediterranean (NOAA Ocean Prediction Center) • Live reality-check: compare your reading to the nearest station’s real observed wind • All future regions, free, forever For sailors, RYA/ASA students, and weather enthusiasts who want to understand the wind — not just read a number off an app. A learning and planning aid — not official, navigation-grade weather data. Always consult official sources for navigation. Charts: © Crown copyright Met Office; NOAA/NWS Ocean Prediction Center (public domain). Observations: NOAA Aviation Weather Center.

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.
