When you want buy a Pro version of Trace My Trail a requester ask if you want buy from Amazon or Google Play. Essentially the versions are exact the same except for the Auto SoS feature that will send automatically a SmS to the 3 numbers configured in the settings. On Amazon Store the version is full automatically instead on Google Play sto the Auto SoS require a little interaction from the user. The user to send out the sms have to click SEND on the screen.

We remember that this feature does not replace the normal emergency functions or acts. You will use at your own risk!
