If youre ever in an emergency situation where you need to call for help, just hit the Panic! button.
Panic! will dial the emergency services number (911 for the United States, 112 for much of Europe for example) you designate, or it can dial from your contacts list or a custom number of your choice. At your direction, Panic! can dial this number when the application launches.
Additionally, subject to limits of iPhone Location Services, it can locate nearby hospitals as well as provide directions to your home. Panic! also interfaces with ICE to provide quick access to your emergency information.
