SOS can save your life. It is an application that notifies the number that you specify by sending an SMS with your exact position via GPS (it includes triangulation by the telephony antennas). In addition, if after the established time you have not stopped the warning alarm, the application will automatically call the emergency phone you have set up and, once the service responds to your call, the hands-free (Speaker) will be activated so you can communicate without have the phone in your hands

The application is translated into Spanish and English, soon more languages will be included.

It has 3 types of notices:

- Warning for inactivity: If the user remains stopped for the time set in the options, the application will show an alert screen with the sound you have chosen. If after the time also configured in the options, the user does not stop the alarm (it stops with just pressing the screen), an SMS will be sent with his position to the phone of the acquaintance that he has selected. And if, after the configured time, the user does not stop the alarm, the call will be made to the emergency services that we have configured. The detection of the position is done via GPS or, if this is not available, via antenna triangulation. This option is ideal for when we go out to ride a bicycle, hiking, etc ...

- Warning by impact: If the user receives a greater impact to the G forces established in the options, the alarm will be activated working in the same way as in the previous mode. This option is ideal for when we drive or make trips, although it can be valid for any other situation.

- Warning by distance: If the user moves further away from the reference point than the one established in the range of action configured in the options, the alarm will be activated operating in the same way as in the previous cases. This mode is ideal for people at risk of being lost (children, people with Alzheimer's, ...) or people at risk of leakage.

All modes are highly configurable, being able to set a different message for each mode or use a generic one. You can choose the volume of the warning, the tone, the vibration, if we want it to show a notification with flashing on the LEDs, send an email (optional and the user must press "Send" to make the sending), etc. .

We hope that this application can save many lives and help many people. We consider that it is a symbolic price for the effort and dedication in performing a service that is a good for all.

Future versions will include new notification modes and improvements in the application. We are always open to your suggestions to make a better and more effective application.
