BareTag Tool Tracker
Smart tool tracking that helps teams instantly find equipment, prevent loss, and stay coordinated in real time.
Overview
BareTag Tool Tracker gives teams a live view of where important tools are, so less time is wasted searching and more time is spent getting work done. What makes it impressive is that it brings the full experience together in one product: real-time tracking, alerts when items move out of safe areas, and a polished mobile interface that turns complex location data into clear, actionable information.
Demo
Description
BareTag Tool Tracker is a full product, not just a single app layer. It combines a mobile client, backend services, and localization validation workflows to support real-time tracking from data collection through operator-facing UI.
Frontend (iOS app) The SwiftUI client focuses on operator experience: live map visibility of anchors and tags, optional boundary/grid overlays, and out-of-bounds alerts.
Backend (APIs + services) The backend supports auth and operational data APIs used by the client, including user/session flow and device-tracking payloads consumed by the map UI. It is deployed through a Flask + Ngrok workflow for remote/mobile connectivity during development and demos, and serves as the integration point for tool status and location updates.
System integration Frontend and backend are designed to operate as one tool-tracking platform: the mobile app visualizes current state while backend endpoints manage identity and data transport. Localization outputs validated in Blender feed confidence into the tracking pipeline for real-world usage.

ContentView uses @AppStorage auth state and a configurable BASE_URL; users move through login/register flows into a tab-based app with map/localizer/account experiences. The mapping layer uses watcher/view-model components to refresh tag and anchor positions and render interactive annotations.Backend (APIs + services) The backend supports auth and operational data APIs used by the client, including user/session flow and device-tracking payloads consumed by the map UI.
