Now, tap on this smartphone app to connect with new friends!

A new smartphone app by an Indian-origin entrepreneur in the US lets you connect with people you have just met by simply tapping on your phone screen, without exchanging mobile numbers.
The app 'Knock Knock' has been developed by entrepreneur Ankur Jain, CEO of Humin, a technology company in San Francisco.
The new app is based on connecting with and remembering people one meets at various events.
Jain plans to market the app as a way for college kids to make connections without the awkwardness around immediately sharing contact information, reported 'Tech Crunch'.
"Thinking back to my first week of college, I remember wishing there was a way to keep track and remember all of the new people I met," Jain said.

"We created Knock Knock as a fun solution that takes the pressure off when navigating these situations, utilising technology that mirrors our real-life social habits," he said.

Users can connect with each other on the Knock Knock network by knocking twice to open the app. The app then searches on a mesh network for those close to them also using the app.
Users can then connect with one another and chat just using the app, or they can choose to share their email, cell phone and other social profiles with the rest of the group.
Users who do not want to share their contact information but do not want to look rude can just share partial information with certain people.

The app also helps users remember the names of those they met and where they met.
The app uses Bluetooth to function. Users don't have to keep Bluetooth on to use the app, but it will activate Bluetooth on their phone when another user opens the app nearby and starts knocking.
