About Ripple
Ripple is a "panic button" that can send it's trigger message to any app that is a "panic responder". Such apps can do things like lock, disguise themselves, delete private data, send an emergency message, and more. It is meant for situations where there is time to react, but where users need to be sure it is not mistakenly set off. This is a BETA version of this app! We are working now to add support to as many other apps as possible. ChatSecure, Orweb, Umbrella, and Zom already have support, these apps are coming soon: Courier, PanicButton, OpenKeychain, Orfox, SMSSecure, StoryMaker.
