Crash

Crash is an instant messaging app available for Android devices. Once downloaded, users can invite others to use the app through their personal contacts. After adding to each others list of contacts in the app, users can temporarily interrupt each others mobile activities by sending a text, video or picture message to get their attention. Once your message is sent, a pre-installed "crash" sound notifies them of a new message. Their activities are temporarily halted and your message appears on the screen of their device. So, if a friend is downstairs or in another room playing music or watching a video from their device and can't hear you, you can "Crash" in on them and stop what they are doing to get their attention.
