About HookTrace
HookTrace is the ultimate bridge between your iPhone’s high-precision GPS and your private automation infrastructure. Tired of cloud services owning your location history? HookTrace puts you back in the driver's seat. It turns your device into a universal GPS sensor that transmits live location data directly to any Webhook URL you specify. Perfect for: • Smart Home Automation (Home Assistant, OpenClaw, Jeedom) • Workflow Engines (n8n, Node-RED, Zapier) • Custom Developer Projects & Dashboards Key Features: • FULL PRIVACY: No third-party servers. Data goes from your phone straight to your endpoint. • BACKGROUND TRACKING: Runs reliably in the background, optimized for iOS 18+. • FULLY CUSTOMIZABLE: Set custom Authorization headers and Device IDs. • BATTERY OPTIMIZED: Choose between "Significant Change" mode for extreme battery saving or "Real-time" for high-precision tracking. • LIVE MAP: See your current location and breadcrumb trail at a glance. Technical Specs: • Standard JSON Payload (Latitude, Longitude, Accuracy, Speed, Battery, Timestamp). • Supports HTTPS and custom Auth-Headers. • Distance-based filters to prevent unnecessary data spam. Stop sharing your life with big tech. Start hooking your traces to your own home.
What’s new
Version 1.0.1 · Updated April 1, 2026
We refreshed the map screen: compact controls for Follow, North up, and map appearance (standard, muted, hybrid, satellite). Start and Stop are clearer, with a consistent size — green outline when tracking is on, red when it’s off. In Settings → Trail history, you can choose how long your path stays on the map (or turn it off). Trail segments use speed-based colors as a simple hint (walking, cycling, motorized). Smaller polish and stability improvements around the map and controls.
