1) Store detail of the person you are meeting.
2) Store details of the place you are going to.
3) Choose a time for the Safecall alarm to expire (a time you would usually be home again).
4) Leave the app and enjoy your meeting!
5) If everything is ok, switch off the alarm before it expires (you will get a warning 15 minutes before that time). No one will receive a message.
6) Only when something out of the ordinary happens and you do not switch off the alarm, your contacts will be notified.
