I called and spoke with them, but they showed no interest. They couldn’t name a single app offering a similar experience, yet rejected mine under Guideline 4.3, claiming it was too similar to existing apps. To me, this is an excuse to block a completely free app that could threaten established players. It feels anti-competitive. Apple has a lot to learn from Google. I wish you success with your project! There are plenty of Android users out there. Apple isn’t everything.
