Guardly is a mobile emergency response system that allows users to quickly communicate with loved ones in the case of an emergency.If you're in an emergency situation, simply tap the app and it will send out an alert to a network of five friends or family members whose contact info you've entered into the app. Via text, e-mail and an automated phone message, responders can see your location on a map -- and, hopefully, dial 911. We like that the app scans your phone's contact list and suggests responders for you. Your responders will then get an e-mail asking them if they'd like to receive emergency notifications from you. The premium version of Guardly, $10 per month, also allows you to send pictures to responders, share your location as you change locations and activate a loud siren.
