18. The League (Android, iOS)
The League (Android, iOS) bills itself as a dating website for people with high requirements, requiring you to get accredited earlier than you will get to match-making. You inform The League your preferences, and it does the vetting for you, matching you up with potential mates who meet your particular standards.
Critics of The League bash it as elitist (and worse), and it is definitely one of many pricier choices with memberships beginning at $29 a month. It is also restricted to 27 cities as of this writing, however in order for you a closely vetted dating service, this can be an choice price exploring.
