Every night from 7 to 8 PM Pacific, the doors open on Knock Knock - 5 Minute Dates. You get five-minute video dates with people near you, one after another, for the hour. Here's how it works. When the doors open, you tap in and we pair you with someone within 75 miles who matches what you're looking for. You talk for five minutes. When the clock runs out, you each privately choose keep talking or pass. Both say keep talking and it's a match. A text chat opens up so you can keep the conversation going. Say pass and nothing happens. No one finds out, and you're back in line for the next date. No profiles to scroll through. No swiping through photos of strangers. You show up, talk to a real person on video, and decide if you want to talk again after actually talking to them once. Sign in with just your phone number. No email, no password, nothing else to set up. A few things worth knowing: - You have to be 18 or older to use Knock Knock. - Dates only happen 7 to 8 PM Pacific, every day. - Chat is text only, no photos, no attachments, and it only opens once you both say yes. - You can block or report anyone, any time. Come back tomorrow night. The doors open again at 7.
