Differentiating OurTime and eHarmony is really simple, since the former is meant exclusively for aging singles above 50. However, eHarmony is also open to the mature community, and it has a considerably larger user base. OurTime focuses more on senior-friendly content, coupled with an intimate atmosphere. eHarmony, on the other hand, has more attractive features, better visuals and more extensive profile customization options. Bear in mind, though, that eHarmony charges a much higher monthly fee than OurTime, and the commitment lock-ins are also longer.
