Knock

Knock started off when we realized that a huge fraction of the calls we make are "status calls" - calls which can be answered in a word, but not sent as messages because of urgency. What we have with knock, is the best of both worlds.. Ease of texting coupled with the urgency of calling. As you send a knock, your friend will see it on their screen, with the ringtone of an incoming call. 60 seconds to reply, and you see the response right on your home screen! Do try the app, would love to get feedback!

Great idea! I think this might be the first app ever to launch on Android first. lol

At first I was like "sigh, another messaging app?" But this actually looks *really* useful, even with a tiny contact list (which is usually my main hurdle with a new messaging app, so that's really saying something).

I was going to add Knock to Product Hunt. And then I saw it here :) @vennindoubt

I really like this. One of those apps that makes wish I was Android.

I'm skeptical of most new messaging apps but this is quite neat

Its so amazing what android lets you do to their mobile phones just because you have an app installed. Very cool UI/UX
