knok is a text messenger that connects people in the moment. As such, it only allows you to message friends that are currently using their phone. Turning off the screen and placing it in your pocket automatically turns knok in silent mode and you can no longer receive texts. Yannick made use of some esoteric combinations of iOS APIs to detect active usage of an iOS device to enable this magical texting experience.
