Pascal Barometer vs Dynamic Sky

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.

Dynamic Sky turns your real weather into a beautiful, living scene. Instead of a list of numbers, you get an animated sky that reflects exactly what's happening outside — sun arcing overhead, rain falling, fog rolling in, snow drifting down, and storms lighting up the horizon. A LIVING SKY Your forecast, rendered in motion. Clouds build before rain arrives, the sky shifts from day to golden hour to a star-filled night, and the moon shows its real phase. It's weather you can feel at a glance. RIGHT IN THE DYNAMIC ISLAND Start a Live Activity and keep your conditions, temperature, and a mini-forecast glanceable in the Dynamic Island and on your Lock Screen — updating as the day changes, no app-opening required. AT A GLANCE A friendly plain-language summary tells you what actually matters — "rain moving in shortly," "warming to 28° later," "a calm, clear night." Plus an hourly forecast and sunrise/sunset times. MAKE IT YOURS Choose from five distinct sky styles: - Classic Sky — clean and natural - Minimal — calm and understated - Cyberpunk — neon nights and retro sunsets - Pixel Sky — playful retro pixels - Fantasy — dreamy, magical skies DYNAMIC SKY PRO A one-time purchase unlocks: - All premium themes - The full 24-hour hourly forecast - A living world — birds, balloons, planes and shooting stars drifting through your sky - Multiple saved locations - Personalization controls for animation and rare events PRIVATE BY DESIGN No ads.
