Description
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. No account, no sign-up, no tracking. Your readings stay on your device.
Barometer is built for iPhone - that's where the sensor lives. An Apple Watch app and complication keeps your latest reading a glance away on your wrist.
