All is simple!
The person uses the phone 16 times a day, in average. This figure is actual for people at any age. In the case when the phone was a considerable time without movement (unused) the program gives signals. If there is no reaction of the user to a signal that, most likely, there could be something bad. In that case the program automatically sends SMS with coordinates to the confidential person. I sincerely believe that it’s better to phone ten times, than once not to be on time.
Aristotle was right, when he wrote: “Motion is the life”.
- program can work off-line;
- the time when the user is asleep, can be excluded from monitoring;
- reaction time of the mobile device is configured in a wide range;
- countdown to the reaction of the program always starts with the last usage;
- minimizing the risk of false operations;
- economical battery consumption;
- SMS- message contains the geographical coordinates of the sender location;
- If there are available required location maps on the recipient’s phone SMS- message of the sender will be displayed without the Internet;
- coordinates are determined, even if GPS is turned off. However, to obtain more accurate results, it is recommended to have GPS when you use this application;
- automatic activation (program starting) after a reboot or turning on a phone;
From my point of view there is no analogues of a such functional device.
Also remember: the smart phone is the friend of the person! At least, I think so! Give it a chance to take care about the health of your relatives.
