About this app

LiSButton is an automated system for alerting close people about a threat to life and health.
In critical situations, there may not be time to unlock your smartphone and send a standard signal for help, and a panic button located in your pocket, on your wrist, on your sleeve, on your neck in the form of a pendant, or just in your hand, can save your life. It is in such situations that it is vital for you to have the LiSButton application on your mobile device, which allows you to automatically send a series of SMS for help both using the hardware rescue button (panic button) and directly from the mobile application (using the soft rescue button). In this case, pressing the rescue button will start the automatic process of notifying your loved ones about your emergency situation. Your coordinates will also be transmitted.
Brief description of the application's functions
1) Automatic sending of a group of SOS SMS (SOS messages) and important text messages (important SMS) to people close to you after pressing the rescue button (hardware or soft).
2) Allows you to quickly and conveniently make calls to the people you need, since the list of callers is presented in the form of large buttons of various colors.
3) There is a separate screen with buttons for calling various services, including emergency services.
Situations of the most justified use of the LiSButton mobile application
1) Falling under the rubble of collapsed buildings and structures.
2) Heart attacks and other cases of a sharp deterioration in health.
3) An unexpected attack by an armed person, robber, rapist or other intruder, when it is not possible to pick up the phone and signal for help explicitly.
4) Application in medical institutions to call medical staff to the patient's ward in case of unforeseen situations with him (a sharp deterioration in the patient's well-being, accidental disconnection of the system, the end of medicines in a dropper, etc.).
5) Getting into a car accident when a state of shock or mechanical blockage in the damaged car prevents you from signaling for help using your phone.
6) Counteracting domestic violence, when the victim of aggression is not able to pick up the phone and clearly signal for help.
7) Signaling for help in any other stressful situations, when it is problematic for a person to quickly contact the right people.
As a hardware rescue button, it is advisable to use a cheap iTag™ Anti-Lost Smart Bluetooth Tracker (selfie buttons are not suitable). Such key fobs are built using BLE technology and operate on one CR2032 battery (better DL / CR 2032 DURACELL) for a long time.
