goTenna for iPhone

Overview — stay connected off the grid

goTenna is a mobile companion designed to keep you in touch when cellular networks or Wi‑Fi are unavailable. Using a paired hardware radio and the goTenna app, users can exchange messages, share locations on offline maps, and send data directly to nearby devices.

Primary capabilities

• Encrypted group and one‑to‑one chats with delivery receipts and automatic retries for unsent direct messages
• Instant peer‑to‑peer transmissions to other goTenna users within radio range
• Offline map-based location sharing so you can see and send positions without a data connection

How it works

• Pair the goTenna device to your smartphone via Bluetooth, then use the app as your messaging and location interface
• Messages are relayed directly between goTenna radios when in range; some features (like SMS relay) extend connectivity through supported networks when available
• The system is optimized for outdoors use — hikers, backcountry travelers, and groups can maintain situational awareness without cell service

Safety tools and urgent alerts

• A programmable emergency alert (push-for-help) lets you broadcast a predefined SOS to contacts or nearby users
• Confirmations and retry mechanisms increase the chance important messages arrive even in challenging conditions

goTenna Plus — optional enhancements

• Rich offline topographic maps and trip statistics to help you plan and review excursions ($9.99 per year)
• Location tethering that continuously shares your position with selected trusted contacts
• SMS network relay to extend reach by routing messages through available cellular networks when possible

Getting started

• Install the goTenna app, pair it to your phone over Bluetooth, and create your contact/group list
• Test range and messaging with your group before departing, and consider enabling goTenna Plus if you want enhanced maps and tracking data

Download the app and pair your device to enjoy reliable off‑grid communication on your next adventure.
