This APP can shout out for help for you and make emergency call. You can add your personal information such as name, family contact and allergy etc for the rescurers. You are free to personalise your emergency call number, main page picture and sound for help. We suggest you use your family's photo as your main page picture since your familiy will be your spiritual support when you are in dangerous. nWhat if Rose on Titanic's didn't have a whistle?
