The Knock Android app offers a clever way to get people to respond back to texts. Some friends, family members and colleagues have no concept of phone etiquette when it comes to mobile messaging and this app provides the perfect wake up call. It literally simulates a call to get their attention.
Yet what the receiver sees on their end is not the same thing the Knock Android app user sees. In place of the typical accept or reject buttons, they are presented the user's original text message and they can swipe to respond either 'yes' or 'no,' or they can share their location. The Knock Android app was created by Dexetra, a Kochi, India-based company.
