Pascal Barometer vs My Altitude－Altimeter GPS App

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.

NOAA Weather Radar & Alerts Live: Track Every Storm in Real Time Watch rain, snow, and severe storms move across an animated radar map built for speed and clarity. Check current conditions, hourly detail, and a long-range forecast for any place you care about. Everything refreshes in real time, so you always know what the sky is about to do. Main Offerings: - Wind & Temperature Maps: Overlay animated wind flow and temperature fields directly on the radar to see exactly where a front is heading. Spot wind shifts and heat build-up long before they reach you. (Pro subscription required) - Hurricane & Storm Tracker: Follow active tropical storms and hurricanes with live tracks drawn from the National Hurricane Center. See the projected path and intensity of every named system on a single map. (Pro subscription required) - Air Quality Index: Check the air quality wherever you are, with pollutant levels broken down clearly. Decide whether today is a good day for a run or a day to keep the windows shut. (Pro subscription required) - RainScope Minute-by-Minute Precipitation: Get a precise nowcast that tells you when rain will start and when it will stop. Time your walk, your commute, or your cookout down to the minute. (Pro subscription required) - 14-Day Forecast & Snow Depth: Look two full weeks ahead with daily highs, lows, and precipitation chances. Track accumulated snow depth through the winter season. (Pro subscription required) - Unlimited Saved Locations: Save every city that matters, from home and work to family and the cabin, and switch between them instantly. Each location keeps its own forecast, radar view, and conditions. (Pro subscription required) This is more than a radar loop. It is an independent weather app built on trusted public data from NOAA, Open-Meteo, and RainViewer, with units that switch instantly between metric and imperial and a map you can actually read at a glance. Whether you are chasing storms across the plains, planning a flight, walking the dog ahead of a downpour, or watching a hurricane approach the coast, you see the same live picture the forecasters are looking at.
