A free app for Android by JLR - Jaguar
You can use this to set security and comfort to your desired level. It allows you to do various safety measures, such as locking or unlocking doors, closing and opening the trunk, and turning on and off the seatbelt sign. You can also use it to set the temperature level of your car. You can also change the sound and music settings.
It works by using your phone's internet connection to send a signal to the vehicle to control the desired function. It works in both the background and the foreground. It works just like the remote control of your car's security and comfort functions.
