uAlert is a true emergency response system that uses your phone’s gps to locate you and, when you raise an alert, sends help your way. It has been designed to offer the fastest and most efficient response in the event of an attack. It includes important features such as automatic video recording, user Check-In, assistU security services, Safe Place, Missing Child Posters, My Diary, Tracker, and more.
