Note: A current altimeter setting for your location is required in order to convert the pressure reading into an accurate altitude. ## Key features - Real-time altitude display - Vertical speed monitoring - Saves max/min altitudes - Airplane mode compatible - Apple Watch support ## Recent user reviews (6 of 6) All indexed reviews: https://appshunter.io/ios/app/pressure-altimeter/id929307651/reviews.md ### 1/5 — Doesn’t work any longer *2024-08-03* App needs updating for motion and fitness setting. **Developer response:** Motion and Fitness setting updated. ### 5/5 — Great app, does what it needs to do. *2024-06-11* No fluff, no ads, just the numbers. I've tried dozens of other barometer/altimeter apps and this remains the best one. ### 1/5 — Apple series 3 support? *2017-11-10* The Apple watch series 3 is out now and it had its own sensor and it no longer needs to be tied to the iPhone. So this app needs to be updated so the Apple Watch series 3 can work independently from the iPhone. Please update this app. **Developer response:** Version 4.0 now supports running independently on Apple Watch. ### 5/5 — Awesome App!! *2015-05-04* I used the App in the B737 today and it worked perfectly! It was so accurate I could see the pressure change as the lavs were flushed! ### 5/5 — Excellent Altimeter App *2014-11-06* This is the best altimeter app out there. Don't be fooled by the other ones. This one is easy to read, simple yet easy graphics. It shows rate of climb or descent. You can even set standard pressure (29.92) a great tool for the flight deck. A versatile tool you could use for hiking or seeing how fast the elevator moves! ### 5/5 — Great! *2014-11-03* Amazingly accurate. Even indicated the change in altitude from when I was sitting, to standing up. Love it. ## Frequently asked questions about Pressure Altimeter ### What devices support Pressure Altimeter?
