The one Barometer you would need on your Watch! Of course, the phone app is powerful, too.

This app provides the following information using the built-in sensors:
• Atmospheric pressure
• Sea level pressure
• Altitude
• Latitude and longitude
• Boiling point of water based on the current pressure

The Watch app also features beautifully designed complications.

This application does not connect to the Internet. The barometer feature supports iPhone models newer than the iPhone 6s, iPad models newer than the iPad Air 2, and Apple Watch Series 3 and beyond.

Using barometric forecasting and tracking pressure helps me understand why some days pain level goes up or down. This app helps me plan my days

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.

Best barometer app l’ve ever used

Simple, user-friendly UI with everything I could get from atmosphere pressure: altitude and even boiling point of water!
