*** iPhone 6, 6+, 7, 7+, or newer iOS device with a barometer only! ***

Use the iPhone 6 or newer's ultra-sensitive barometer to calculate your altitude. Will find your nearest airport or allow you to enter your local airport's IATA code to calibrate! Perfect for VFR pilots as a secondary altimeter!

**Currently only supports airports in the United States as well as typical USA units (pressure in inHg, altitude in feet)**

What's New

Version 1.42

- Auto-detects nearest airport!
- Keeps the screen on while active and properly resumes from background
- Speaks your altitude on launch and every 1000ft (on ascent and/or descent, see settings)

Ratings and Reviews

Simple, clean app


Gets the job done

Amazing and simple app!


As a new pilot and someone who grew up in the mountains, altitude is a huge interest of mine. Therefore I was extremely excited when Apple announced a barometric sensor in their new iPhone 6. Ever since I got the new phone I have been looking for an app to tell me my current altitude, not just a difference in altitude. This app does just that by using current Metar data from an airport of your choice (choose closest airport for accurate altitude). This app is simple and is brilliant! Definitely worth the $1! My only recommendation is to have a automatic airport selection based on your current location. 5 stars!!!

Needs a little love

I like the premiss but when manually entering an altimeter setting the menu selection won't allow you to see the altitude. No way to drop the menu. I would wait until they play with it a little.
