# Introduction **Welcome to the Trackversal Project!** This documentation page contains everything you need to know about Trackversal from a developer standpoint. This includes: * **API Reference:** How to interface with the Trackversal backend to authenticate users, register devices, send update pings, and more. * **Hardware Specifications:** How you can build your own DIY Trackversal tracker, and information about LTE/Bluetooth/GPS functionality. * **Users' Guide:** An overview of supported features in the official Trackversal app. ### **What is Trackversal?** Trackversal is an **all-in-one tracking device.** It combines the power efficiency and low overhead of a Bluetooth tracker (such as Tile) while retaining the long range and versatility of GPS trackers. When a Trackversal device is near your phone, it automatically switches to Bluetooth mode. When you walk away and get out of range, it automatically switches to GPS mode. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
