Great E6B

I love this app. One thing to adjust - for newer iPhones, there is a portion of the display of menus at top that get blocked by the notch for the top speaker: I use an iPhone XS Max. It would also be nice to be able to zoom out further so the entire e6b slide rule can be displayed. Otherwise, a handy app!!!!

Perfectly simple.

Very well created. It’s simple and straight forward. No ads! Functional for both using and teaching with. I no longer have my handheld.

Very well done E6B

Once you get accustomed to using a classic manual e6b, it is hard to beat them in terms of speed and efficiency. This is a very well done emulation. I'm looking forward to demonstrating how to use this great tool online.
