This app is 5 stars for me

Very easy to use with one hand -- and it is accurate on both sides. Right now this is the best electronic E6B out there. However, I would like some higher resolution graphics if the author has nothing better to do. If the ads bother somebody then buy the Pro version for $2.99.

E6b review

Great app for when you forget your physical E6B or when trying to show someone how to use. Only reason I knocked one star is because the 0 degree air temp mark is not centered over the zero line. It's on the -5 degree line, which is a little irritating because I have to count down from the 50 degree mark to find 0 line. Hope to get update to have it fixed, then I would rate 5/5.

Perfect action without the grit between the components! If you've had a real E6B, you know what I'm talking about. I already know all the formulae and conversions, all I need is what is depicted. A masterpiece of simplicity and utility. Bravo
