goTenna Mesh - pair to your phone to create a long-range, off-grid communications network!

goTenna Mesh Off-Grid Communication Tools - With the goTenna Mesh you can privately and automatically relay messages through other devices to extend beyond point-to-point range with revolutionary mesh technology. You can also send text messages as easily as with your favorite texting app except you don't have to rely on cell towers or routers for service. Chat 1-to-1 or in groups of up to 10. Count on delivery confirmation receipts for every message, so you can be sure that you're getting through to the other side. Download free, detailed offline maps of any location in the world. Save and share pins so you can find yourself and others effortlessly. No towers or routers means no central data-store. That means what you say is between you and your network. An added perk? Your private chats are end-to-end encrypted.
