LiS is a free iPhone app developed by LIS LTD that aims to provide peace of mind for parents and instant help for those in life-threatening situations. With LiS, parents can always know the whereabouts of their children and instantly receive a distress signal if their safety is at risk.

The app's algorithm allows parents to call for urgent help if they or their child are facing violent actions. It also empowers children to independently call for emergency assistance with just one button press. In case of an emergency, LiS can instantly transmit audio recordings of the child's surroundings to the parents.

LiS goes beyond personal safety by offering features such as reporting missing loved ones in the "Search" section and providing immediate access to a photo, name, and age of someone in need of help. When the SOS button is pressed, LiS not only shares the user's geolocation but also provides details such as floor, apartment, and other specific landmarks.

Users can respond to SOS signals and offer help themselves or call emergency services through the app. It's important to note that individuals are free to choose whether or not to participate in providing assistance.

LiS also enables remote interaction between users during rescue operations and allows users to express gratitude to the rescuers at any time, as all information is stored in their history.
