'Knock Knock' is a new app that helps you share contact information with new people simply by knocking twice on your phone. When meeting someone for the first time, it can be intimidating to ask them for their phone number. This app makes it easier to share limited contact information simply by tapping on your phone.

In order to use Knock Knock, both users must have the app. These individuals can then swap contact information simply by knocking twice on their phone. The act of knocking will trigger the phone's accelerometer and gyroscope even if the screen is off. The app then uses beacon technology to notify users who are in Bluetooth range. The other person has the opportunity to choose whether to share their contact information or not. The user can also choose how much information to share.

The app is perfect for those who want to skip the awkward process of asking for someone's number after meeting for the first time.
