Plan events and get RSVPs fast! KnokKnok invites vanish when the host get's enough takers so guests learn to act fast! Perfect for last minute get togethers!

KnokKnok text invitations VANISH when you get enough takers! Happy hours, house parties, cookouts, babysitters, exercise buddies....if you are trying to gather people and don't want to have to wait for replies- send a mystery knock and they will only see the invite if there is still room! You can reveal as little or as much as you want in the invite (host, who else is coming, who else is invited)!

When you have your target number of friends accept, the invite vanishes and anyone who didn't respond won't know who it was from or what it was for- just that they are too late!

Recruit the perfect number of friends every time, even at the last minute!

Life is more fun with friends! Let KnokKnok find out which of your friends are available and ready for adventure!

FRIENDS: Find friends from phone contacts or search KnokKnok users! Share KnokKnok with your social networks or contacts. College students are auto-friended with other students at their university to make those house and dorm parties a snap to plan. Create groups of friends for faster invites.

INVITES: Send invites with texts or in-app notifications. Friends know they have been invited to an event, but they won't know WHO or WHAT until they RSVP! Once the max number of friends accept, the invite vanishes. Sync invites with your calendar!

CHAT: Chat free with KnokKnok! Group chats are automatically created for every event so it's easy to coordinate. You can also chat direct or create your own group threads.

CROSS-BLOCKS: Amazing! If you have friends who just don't get along, upgrade to get access to Cross-Blocks! Cross-Blocks allow you to set a block by invitees; if Friend A accepts first, the event vanishes for Friend B, even if there is still room! No need to worry about social meltdowns!

AND MORE: Have you ever wished that you could take back a text invitation because a friend is slow to respond and you want to move on? With KnokKnok; invite everyone and the invitation automatically closes at your attendee limit! No one will feel left out because they won't know it happened. Let your friends’ responsiveness determine if they are going to attend!
