A phone app to aid in communications during emergencies.
HelpBridge lets you put together a list of friends and family members you would want to notify in the event of a natural disaster. Then in an emergency, the app lets you quickly send email or text message alerts letting those people know you're safe or require help. It can also post an emergency message on your Facebook Timeline.
