What is the opposite of Grindr?

Could you elaborate on what you mean by "the opposite of Grindr"? Are you referring to a dating app that caters to a different demographic or serves a different purpose entirely? If we're talking about a dating app that targets a different group, perhaps you're thinking of apps like Tinder, Bumble, or Hinge, which are popular among a broader range of users. However, if you're looking for an app that serves a completely different purpose, it's difficult to pinpoint a single "opposite" without more context. Could you provide some additional information about what you're looking for?
