We developed Duet®, our exclusive Total Compatibility System, with leading relationship authority Dr. Pepper Schwartz. Duet® is the result of over 30 years of scientific research. This unique system is grounded in a serious exploration of the characteristics that lead to successful relationships.
Duet® is proven to be more effective than any relationship tool on the Web. By identifying your traits, we determine your romantic compatibility type and suggest ideal matches for you. And unlike the eHarmony® experience, you’re free to accept those matches or do your own search based on any criteria you choose.
