Venues in San Francisco

Find out if it's mutual — before you say a word.

Chewing Gum is a venue check-in service in San Francisco. Scan the QR code at a participating venue to check in, privately offer a piece of gum to someone who's also there, and you'll only ever hear back if they offered one to you too. It's free, you can use it anonymously, and sharing a phone number is always your choice.

If you opt in, we send SMS for two things only: a one-time code to verify your number, and a text to let you know when it's mutual. We never send marketing texts. Reply STOP to opt out or HELP for help; message and data rates may apply. Full details are in our SMS policy.
