BTW, as a creative person, I personally can't stand it when people's only comment is "have you seen X Y and Z which are similar to what you've built?" I get it, reinventing the wheel isn't always the best use of time, but I wish people realized how much of a wet blanket that sort of comment can be, especially if it is unaccompanied by any other insights about your work. It seems to imply that you haven't done anything worthwhile or unique, and your efforts are a waste of time.

I hope you continue to build this out into a product. Good luck with it and congrats on all your successes at a very young age.
