If you want to protect yourself from muggers or any potential danger on the streets, you might find Coyote Case more than useful. This case is rugged, so it will protect your iPhone from drops and scratches, and at the same time, it can emit a 100dB siren that will scare off the attackers and draw attention to you. In addition, this case can be customized to send out a text message and your current location in case of emergency. Coyote Case comes with two buttons on the back, and they can be customized, so you can use one button for siren, and the other one for emergency text message, or you can set that siren is activated by pressing both buttons, so you can’t turn it on by accident.
So far, Coyote Case is Indiegogo project, but if you help its funding, someday it might become a reality.
