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 — or lets you adventure solo.

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.

New: Solo Mode Hiking alone? Start a solo trip with one tap — no group needed. Your location is never broadcast, while offline track recording still works. Your trip is restored automatically if the app relaunches.

New: Track Recording & Sharing Record your route offline with distance, duration and elevation stats. Share a beautiful track card with your nickname, or export your track as a GPX file for OsmAnd and other outdoor apps.

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.

Lock Screen & Widgets See teammates' status on your Lock Screen with Live Activity and Dynamic Island, and check online count and nearest teammate right from your home screen widgets.

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.
