The design of a pet tracking system using GPS with an android-based geofencing method was driven by the increasing interest in owning pets during the pandemic, to make it easier for pet owners to find these animals, this system was developed. The system developed aims to prove that geofencing technology can make it easier to find pets with the help of technology, in addition to using an android-based application to find out the location of pets and find out the accuracy of the pet's distance from the homebase. The methods used in the development of this system are the creation of hardware using the ESP32 microcontroller and NEO7M GPS, as well as the creation of an android-based application to make it easier for users to track the whereabouts of pets, the application also allows to know the distance of the animal from the homebase to the location of the pet. From the tests carried out, the average accuracy of devices with GPS-based applications is 92%, this tracking system also has disadvantages when tracking inside the building delay time approximately >3 minutes while in open area conditions it takes 3-5 seconds to get latitude and longitude data. The developed system can show precise location but must be developed better regarding battery selection and signal problems when inside the building.
