## What is KnokKnok?

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!

MORE GREAT FEATURES:

> 50 free SMS text invite credits
> Unlimited in-app or web link invites
> RSVP tracking for host 
> Short Links allow non-iOS friends to RSVP
> Add events to your calendar
> Controls for left-handed users
> KnokKnok widget highlights new and upcoming events
> Invite friends with custom SMS messages so they know it's really you!
> Support for virtual events

Supercharge your social life with spontaneous get togethers in real life. With KnokKnok, you don't have to choose between inviting friends via individual texts or risk large crowds with group threads- KnokKnok lets you put out a digital flare and retract it without a trace once you find like-minded friends.  Party planning has never been easier!
