Personal safety app
A personal safety app or SOS app is a mobile application designed to provide individuals with additional security and assistance in various situations. These apps offer a range of features and functionalities that users can utilize to enhance their personal safety. Common features include emergency alerts, location sharing, safety tips, SOS buttons, audible alarms, and community safety reporting. Users can employ these apps to quickly send emergency alerts, share their real-time location with trusted contacts, and access safety-related information and resources.
Features
While most personal safety apps are offered as freeware, some are either distributed as a freemium app with paid features which can be unlocked through in-app purchases, supported through advertising, or marketed as paid applications. These include various features, including sending text messages, e-mails, IMs, or even Tweets to close friends or emitting a loud intermittent "shrill whistle" in the manner of a rape alarm. Additional features include geofencing and preventive alerts. Some apps allow to customize the alert message sent and the ringtone that signals the reception of a new alert.They normally include different triggering mechanisms to cope with different emergency situations. Common triggering mechanisms include pressing and holding the phone's switch button for a few seconds, shaking the phone vigorously, tapping on an alert button, and even loud screaming sound which the app can detect. When the alert signal is triggered, these apps automatically go to work, sending text messages and emails with exact location of the user to emergency contacts listed on the app.
