Foursquare
Foursquare helps you explore the world around you. Keep up with friends, get insider tips, and unlock discounts and rewards.
While on the go, you can easily tell friends where you are, share pictures, get their comments (“I’m right around the corner, I’ll stop by
to say hello”), and get insider tips (“order the Lobster Ravioli; it’s the best dish by far.”). Tons of places offer discounts and freebies to
Foursquare users, and you earn points and badges for doing the things you love.
Have fun exploring!
