Whisper is a proprietary iOS and Android mobile app available without charge, which says that it allows users to send messages anonymously, and to receive replies. Users post messages which are displayed as text superimposed over an image, similar to greeting cards. The app was launched in March 2012 under the original name Whisper Text by CEO Michael Heyward and Brad Brooks, who is the CEO of mobile messaging service Tiger Text. https://en.wikipedia.org/wiki/Whisper_(app)
