Pressure and altitude. Beautifully clear.
Barometer turns the built-in sensors on your iPhone, iPad and Apple Watch into a clear view of the conditions around you. Check a reading at a glance, follow pressure changes, or explore your altitude as you climb.
PRESSURE, IN PERSPECTIVE
• Atmospheric and estimated sea-level pressure
• Pressure history, trends and changes over time
• A pressure-based weather outlook
• Optional pressure-change notifications
A CLEARER VIEW OF ALTITUDE
• Altitude readings and elevation charts
• Calibration using a known altitude or available sensor references
• Ascent, descent and elevation range
• Latitude and longitude
• Estimated boiling point of water at the current pressure
MADE FOR YOUR DEVICES
• A dedicated Apple Watch app
• Watch complications and iPhone widgets
• Siri and Shortcuts support
• Control Center shortcuts
• Your choice of measurement units
• CSV export for saved measurements
Core pressure and altitude measurements work offline using your device’s sensors. Location access enables additional information, including estimated sea-level pressure.
Requires iOS 26, iPadOS 26 or watchOS 26. Available readings depend on your device’s sensors and permissions. Pressure-based weather information is an estimate, not an official forecast.
This app is awesome, however the watch version has not worked since the last iOS update. Really miss the watch app.

I M a science teacher. Weather is one favorite subjects. This app is a great. Weather observation is a vital part of it. This barometer is accurate. I enjoy all the stats. I was wandering how I can see trending levels as it moves up or down for future forecasting.
Awesome app

I use this app daily. It’s amazing to think I wanted a real Mercury barometer. But I saw this and didn’t even know my iPhone had one. So amazing. Thank you so much for designing this. Your awesome Justin.
