Blindspot is an incognito messaing app that is designed to make it possible for you to send anonymous messages to anyone in your contact list. The app is solely focused on private chats between two people rather than group chats. What's unique about the app is that the receiver never knows who a message comes from.
The Blindspot messaging app's page on the App Store and Google Play ask you to consider, "What would you say to people you know if you were anonymous?".
This sort of philosophy puts a whole new spin on messaging by making it anonymous, thereby encouraging people to step out of their comfort zone and say what they want without fear of retribution or embarrassment. This app could be used for everything from setting scores to harmless flirting and more.
