## What is TrailLink?

TrailLink is the ultimate offline communication app for hiking, camping, mountaineering, and outdoor adventures. When you are off the grid with no Wi-Fi or cellular signal, TrailLink keeps your team connected.

How It Works
TrailLink uses Bluetooth Mesh technology to create a decentralized peer-to-peer network between nearby devices. Messages hop from phone to phone, extending your reach far beyond Bluetooth range.

Key Features

Offline Mesh Messaging
Send text messages to your group without internet, cellular, or Wi-Fi. Perfect for remote trails, mountains, and wilderness areas.

Real-Time Location Sharing
See your teammates' positions on an offline map. Know exactly where everyone is, even in the most remote locations. Share your location automatically or manually with one tap.

One-Tap SOS Alert
In an emergency, press and hold the SOS button. Your location is instantly broadcast to all team members with full-screen alerts, vibration, and sound. Help finds you faster.

Offline Maps
Download maps before your trip and use them completely offline. No signal? No problem. Your team's locations are always visible on the map.

Group Management
Create a hiking team, share a unique group ID and password, and invite members via QR code. Everyone stays in sync.

Private and Secure
All communication is encrypted. No personal data is collected, no servers involved, your privacy is protected.
