Who should use it: Those who want a service that's more personal than the average dating site. The Dating Ring uses both algorithms and a human matchmaker to send paying customers a minimum of one match a week or one per month. It'll cost from $30 to $60 depending on subscription (there's also a free service but there's no minimum guarantees). It operates in New York City, the Bay Area, Los Angeles and Boston. It's not a dating app (yet), but is available on desktop.
