Ratings and reviews

So I do like the app however it is not accurate. Check the density altitude against a physical E6B. One example would be -50 at 35,000 feet, you will note that the density altitude is off by more than 1000 feet. I reported this anomaly via email a few weeks ago and have not hear back. It's a great tool and it does seem accurate for general aviation calcs but it does give me doubt when it's wrong on some calcs. Also I check the app on both Android and iOS devices and various devices sizes.
