Tracking Device
Awesome way to keep track of your loved ones.
Uses Android GPS but does not kill your battery.
Starts the GPS when someone requests your location. Then shuts it down.
Uses encryption to scramble text that is sent across the network.
Only use this app if you have unlimited SMS.
You can block people if you don't want them checking your location.
Bypass encryption mode for people that do not have this app. They can send you plain text and receive your location (from an iphone for example)
Sends google map link to anyone requesting your location.
Small, lightweight, never have to worry if it is on.
