Not being a hater but launching here seems silly from the POV of marketing. This seems like something that would get traction rather quickly if pushed in the right context.
Trust me. Put ads on facebook with your target demographics and search IG for women of color with a good amount of followers. That stuff works like magic.
Edit:
If you email me I can introduce you to one such group that has a lot of active users and is led by a black lady. You can pivot from there.

Just realized my comment makes me sound like a huge dick. Not my intention. Im excited about the product and wish you the best of luck. I do feel strongly about marketing it (even if not my own project) and that made te words come out too strong.
