HUFFINGTON POST – Dec 10 – Susie Lee launched Siren, a female-friendly dating app, two months ago. Siren allows women to control their own visibility. Users choose who gets to see their photos and when, exactly, they reveal them. After two months, the app gained 9,500 members, and the female-to-male ratio is 53:47 across all ages, according to Lee. There is no swiping, users get to know each other through a “Question of the Day” forum.
