Very good emulation

The zoom feature is excellent and really makes it useful as E6Bs tend to be very small print, and other apps that tried to do the same but won’t let you zoom don’t help at all. The wind side of your E6B is perfect; I love the way one can change the wind vector “remotely” by not having to have the finger on top of the vector. The IFR holding pattern calculator is one of the best I’ve seen.

Now, some things can still be improved... :)
- Support landscape (I think that should be a rather low hanging fruit)
- Also, make support of iPad multitask a priority so that it can be used side by side with / on top of e.g. ForeFlight
- Please also make the outer disk of the E6B rotatable just like the inner disk so as to not have to turn the device. At the very least, if you don’t implement this please block the up-side-down support so that at least rotating the device works
- Lastly (lowest priority) - can you make the footprint of this app smaller..? A quarter GB seems quite wasteful for a small app...

Thanks for an almost perfect emulation of the original E6B!

Wonderful flight computer

Very accurate flight computer. I use it for teaching in the classroom.

Would like to be able to draw colored lines on the various scales in order to show students sitting in the classroom how to line up the scales.

Otherwise, it works great and is accurate.

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.
