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.
