Foggy autumn forest with a GPS blood trail path

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).
