Why do you ever need an E6B app?
They are not permissible at the written exam, and there are easier ways in the cockpit and at planning time.
You can use an E6B for the PPL written. Not sure about the others, but I can't see why they would allow it for that, and not others. I had mine from 15 years ago, but the testing center even supplied one for me, in case I didn't have mine.
An E6B, yes, an E6B APP, not so much.
Just learn the math behind it, it's really middle school level stuff.
I can do it by hand, or any calculator, saves your bacon and saves money.
