This is fun. I have always said that a portion of my brain is dedicated to the fretboard. If I'm talking about intervals without an instrument in front of me I am always imagining the fretboard to find, say, a minor 6th from C#. I know the shapes of octaves across different strings very well, so even in the red zones I can find the notes pretty quickly. I cannot say the same for many of my bandmates, as talented as they are.

I completely understand you wanting that. My concern is that I offer a 1 week free trial for all new accounts. There's nothing stopping people from making a new account every week with 10minutemail to use the app for free. Happy to make a "backdoor" email only account for paid users though.
