"nocknock is a fun new app for iPhone to quickly chat with people around you. It uses your phone’s Wi-fi or Bluetooth to initiate one-to-one connections and then uses them to communicate between the phones. Of course, this means the other person needs to have nocknock installed on his/her phone too. But the benefits of this are that there’s absolutely no signup involved, nothing is sent or received via any servers. It has a lovely UI and offers a fun way to chat with random people." - review from beautifulpixels.com

Chat with people nearby, totally anonymous, absolutely free! Chat on cafés, bars, busses, trains, conferences, hotels, airports, in schools. When you are abroad with data roaming turned off. Anywhere.

This app uses Bluetooth and Wifi only to communicate. No Internet. No registration needed. No servers involved. No Surveillance Agencies. Nothing.

FAA now allows the use of smartphones in-flight in the U.S.. using Wifi or Bluetooth, if you have disabled the cellular connection. The implementation may differ between airlines. This means 'nocknock' is your perfect in-flight companion if you want to chat with friends or colleagues on the plane. Read more at:

If no one else is using this app, it is pretty much useless! So spread the word and fill the world with happy nocknockers!

Others may only find you if this app is running in the foreground. If you can't find anyone nearby, turn the phone sideways to show a message to others, letting them know you want to chat. Be patient. They will come. They will.

The world is what we make it. Be nice to people around you. Feed your karma. Compassion is good. Love is good. Be fun. Have fun! /the nocknock team!
