Trail Tracker — GPS Blood Trail App
Mark blood sign, record your walk, and find your way back to the truck — built for wounded deer recovery in the timber.
Install to your home screen for full-screen use with gloves. Open once on Wi‑Fi to cache maps for offline.
🩸 One-tap pins
First blood, heavy, last, bedded, and arrow — large buttons you can hit with gloves on.
📍 Live GPS path
See every step on the map. Distance walked and a line back to your start point.
🧭 Back to truck
Bearing and straight-line distance to your start — so you don’t get turned around.
📤 GPX export
Save hunts and export to onX, Gaia, Google Earth, or share with your tracking party.
🛰 Satellite maps
Aerial imagery like HuntingPoints — plus hybrid, topo, and street views. Tiles cache for offline use.
🌙 Dark & offline
Night-friendly UI. Works without cell signal after your first load.
📝 Pin notes
Tap any pin to add terrain, direction, or blood color — while it’s still fresh.
📷 Blood Detector
Point your camera at the ground — live HSV detection highlights blood sign and can auto-drop GPS pins (full app).
