If your bottom line is gross revenue, why not just A/B test your pricing?

In an app store this is really simple. Pitch the app at a different price tier every week (ideally during a stable period with no major public holidays or obvious seasonal variations). One week will make more money than most. That's your price.

What you're describing is not really A/B testing.

Real A/B testing would mean to simultaneously show to different users, different pricing for the same product and I believe in some jurisdiction this could get you into a trouble legally speaking.
