How this is calculated
Apple publishes no download counts. iPhone downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.

About Pascal 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.
