Tinder

The platform caters primarily to tech-savvy individuals aged 18-35 seeking casual interactions, but it also supports those looking for serious relationships.

On Tinder, users "swipe right" to like or "swipe left" to dislike other users profiles, which include their photos, a short bio, and some of their interests. Tinder uses a "double opt-in" system, also called "matching", where two users must like each other before they can exchange messages
