I was about to recommend this app to some friends, who happen to be trans. I'm a non-binary male who happens to be partially comfortable with their own assigned gender at birth, but this would be problematic for transgender folks who want to improve their health and be included, and this is a huge necessity in such a marginalized community. Moreover, their biology it's a more complex factor, considering most of them engage in HRT and their biomarks would be more prone to their identity rather than assigned gender at birth. Thank you for your consideration.
