MASHABLE - Feb 5 - One in five Americans have engaged in consensual non-monogamy. And yet, there are no good dating apps for non-monogamous people. Many of the apps used by the non-monogamous community are "trash" or solely for sex, said Steve Dean, online dating consultant at Dateworking.com, a dating coaching and consulting business. Dean, whose been non-monogamous for the past nine years, referred to one called Pure, as "Uber for sex." Feeld is another one that falls into the hooking up category. Then there is #open, an app that claims to be an inclusive community for any type of user. 94% of the app's 40K users report they prefer some form of open relationship, according to #open's cofounder Amanda Wilson. The most "mainstream" app that provides a tailored experience to non-monogamous people is OkCupid. In 2016, OkCupid added a feature for polyamorous couples. It subsequently replaced its "open relationship" status option with the term "non-monogamous." Dean said OKC is the best app for non-monogamous people right now, but technical changes have made it "virtually useless." This is because a 2017 change that filtered out unwanted messages had an adverse effect.
