Why you would wish to have tracking software in your phone.

Children like playing in school and hung out together. It happens that while going home your child boards a different bus which heads absolutely in the opposite direction from home. Its only late enough that you notice that your child has not arrived then do you start raising an alarm. If you had a phone with tracking software, getting to your lost child would be very easy and quicker.
You happened to alight from a bus and from the long days work you hardly remembered that you had a language bag and you discover that it has been left inside and the bus has left. This would really be a stressful moment especially if you had valuable items in your bag like a laptop and business papers for example. If your laptop had a tracking device or software setup, it would provide an efficient means to recover your items.
With the increase rate of crime, cars are not spared by car jerks who pounce on any vehicle that looks good and can bring in money fast. If you were to be hijacked and your car stolen, most of the cases are where the thieves run away with phones. Tracking your phone would be a start to get your vehicle back. This brings in a double benefit. One is that you will recover your phone back the second is that you will get you car back.
The cost of getting a mobile software mobile tracking setup in your phone is far more worth compared to the situations that you would encounter and regret wish you could have gotten the software installed before time.
