Tinder was founded in to address the social and physical barriers of forming new friendships with people in your area or in your social groups. Tinder anonymously finds out who likes you nearby and connects you with them only if you’re also interested. Tinder collects social graph and behavioral data on its users to make the most accurate suggestions on who they should consider knowing nearby.
Here’s how it works:
1) Tinder shows you someone nearby it thinks you should know, and lets you anonymously like or pass on them.
2) If someone you like happens to like you back, then Tinder makes an introduction & lets you chat within the app.
