Handy app as long as you are connected

My darling wife got this app for me. We live 17' above sea level so it came in handy during last months trip to the Rockies. It was accurate when we drove up Mt. Evans. But in the Tetons, reception was intermittent -- also on the airline. Still, an interesting tool to have.

Does exactly what it promises and does it very accurately

This app does exactly what it’s meant to do and does it without any fuss, unnecessary features, intrusive advertisements, and is extremely accurate in my experience. I have compared readings to public signs I with published altitude/elevation information and googled web-related results (of altitude information for a few different locations) and it is always spot-on. I was even able to confirm that it was able to give me an altitude measurement 31,500 ft in the air (on a commercial jet) and that measurement was also confirmed by the pilot of the aircraft (he announced it). Long-story short is that this app is literally the best, the most accurate, the most polished, and the most focused application for altitude/elevation measurements on IOS, in my opinion,after testing like 10-15 other altitude apps. Keep in mind I have relatively new hardware (iPhone XS Max) and I have the latest IOS version so your results may vary if you have older hardware or you are using a device, like an iPad, that may be missing all of the various sensors that I have.

Most accurate altimeter I've found

Been using my Watch for altitude information when flying my ultralight aircraft and found other GPS altitude apps to be completely inaccurate and not precise at altitude. Using the barometric function with Altimeter+ has been incredibly accurate. I used it for a flight this morning and 15 hours later at a known elevation, I'm basically right on with the baro altimeter.
