Knock (Beta) 1.4

Knock is a message which acts like a call. When you knock a friend, your friend receives a call, and can see the text written on the screen. You get a response within 60 seconds.

Knock is completely free - both to install and use. Knock uses your 3G or WiFi(when available) to communicate with friends.
Sending a knock is as simple as sending a message. When you get a knock, you can respond with a single swipe. You can respond with a yes/no/message/call or location. The response is visible in the home screen.
Knock completely eliminates the necessity to call for questions like:
- Have you left yet
- Where are you
- Is dinner on today

Knock is ephemeral like Snapchat, real time like Viber or Skype, simple setup like Whatsapp or WeChat.
But realtime and effective like a phone call!

* For Dual-SIM phone users: For successful verification and registration, please use the phone number in SIM 1 to register. Else, number verification might fail. We are sorry about the inconvenience, we are working on a fix and will be releasing it soon.
* Number and contact blocking coming soon.
