Zambretti Barometer

About

Turn your iPhone into a precision barometer. Your iPhone has a real barometric pressure sensor built in. Barometer puts it to work. See live sea-level pressure, watch the 3-hour trend, and get an early heads-up before the weather turns. Everything reads at a glance - on your Home Screen, your Lock Screen, and now your wrist. A live pressure gauge A beautiful, crafted dial shows your current mean sea-level pressure with a live 3-hour trend - rising, falling, or steady - plus clear 6-hour and 24-hour reference markers so you can see exactly where things are heading. History at a glance. Scroll back through 24 and 48 hours of pressure on a clean chart, so a passing front or a building high is obvious. Storm & clearing alerts • Barometer-derived alerts read your pressure and its trend to call storms early and tell you when it's clearing • Delivered as on-screen banners and optional background notifications, so you're warned even when the app is closed A classic barometer forecast. The time-honoured Zambretti method turns your pressure, trend, and wind into a plain-language forecast - computed from your own barometer, correct for both hemispheres. Feel the weather before you see it Many people sense pressure changes in their body before the sky shows a thing: headaches, migraines, sinus pressure, aching joints. Barometer helps you connect the two. • An optional wellbeing log records how you feel and stamps each entry with the real pressure you were experiencing - the actual air around you, not just the sea-level number • A summary builds as you log, showing what the pressure was doing when you felt off - falling, steady, or rising, low or high • Look back over time to spot your own patterns • Private to you, kept on your device, never shared Your sensor vs. Apple Weather Barometer pulls in Apple Weather for temperature, wind, and the official sea-level pressure, then shows your iPhone's own sensor reading side by side - so you see your exact local conditions, not just the nearest station. Built-in widgets • Live pressure on your Home or Lock Screen • The 3-hour trend, a 24-hour chart, and any active storm alert • One glance away, no need to open the app On your wrist • An Apple Watch app with your live pressure, trend, and 24-hour chart • A watch-face complication so the current reading is always one glance away • Stays fresh on its own with Apple Weather, even when your phone is out of reach Made yours • Eight hand-crafted colour themes, with System, Light, and Dark appearance • Your choice of pressure, temperature, wind, and elevation units • A recording log of every reading, with one-tap CSV export Extra tools • Density altitude for shooting and ballistics, in feet or metres Private by design.
