SMARTR sends a signal to the SMARTR App on your phone when you leave your car behind unlocked, enabling you to simply lock it and leave. If you wish to check up on your car from a distance, then the SMARTR App will enable you to do just that. It can tell you whether your car is locked, anytime, anywhere.
