Pascal Barometer vs iBarometer

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.

iBarometer turns your iPhone into a professional-grade barometer. Powered by the built-in pressure sensor, it delivers real-time atmospheric pressure readings with beautiful precision gauges and trend charts. KEY FEATURES • Real-time Pressure — Live atmospheric pressure in hPa, inHg, or mmHg with a stunning gauge display • Trend Indicator — See at a glance whether pressure is rising, falling, or stable with change rate tracking • Altitude Display — Absolute elevation above sea level and relative height changes • History Charts — Visualize pressure trends over 1H, 3H, 6H, 12H, or 24H periods • Fishing Activity Score — Know the best times to fish based on pressure patterns • Offline Ready — All readings work without internet, perfect for remote locations FOR FISHING ENTHUSIASTS Barometric pressure directly affects fish behavior. When pressure drops rapidly, fish feed aggressively — that's your window. iBarometer helps you spot those moments with real-time trend tracking and a simple fishing activity score. FOR OUTDOOR ADVENTURES Whether hiking, climbing, or just curious about the weather, iBarometer gives you the atmospheric data you need. Track approaching storms before they arrive with falling pressure alerts. Upgrade to Pro to unlock: • Fishing Prediction — Detailed bite forecast with species-specific tips and best time suggestions Works with iPhone 6 or later. No internet required for core features.
