With the development of economy, people's living standards are improving day by day. Nowadays, people begin to own more and more relatively valuable items, including but not limited to bicycles, private cars, smart furniture, smart appliances, etc. Some of them have corresponding anti-theft measures, such as the built-in anti-theft system of the car, the positioning system of some smart devices, etc., but most of the items have no anti-theft and recovery mechanism after being stolen.

For the above problems, this article provides a general solution based on geo-fence technology for anti-theft and tracking and retrieval of stolen items. And based on this design and development of a cross-iOS and Android application. This article describes in detail the specific design and implementation process of the new APP.
