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.

This is a great and simple app that does what you need. However as someone else said, the autorotate is problematic. I appreciate that you can access landscape view, but it would be better if you could lock it into one or the other so it doesn't keep jumping around. I'd give it 5 stars if that was fixed!
