GoTennas keep you connected where normal cell phones fear to tread

Add as a preferred source on Google

The GoTenna is a rugged digital radio that ensures you can always stay in touch with your hiking partner, whether or not you have cell service. It connects to your phone via Bluetooth, and it allows you to chat one-on-one and share your location up to 50 miles away within line-of-sight. That number falls with obstructions, but we had no problems staying in touch within a mile apart from each other with hills  between us. This makes the GoTenna ideal for camping, hiking, and road trips where cell service isn’t available, or for crowded areas where cell service is bogged down by traffic.

Initial setup requires you have a cell signal or Wi-Fi before you take it out, so you’ll need to plan ahead and get it working while you’re still in civilization. Download the GoTenna app, follow some short registration steps for each antenna, and once registration is complete for each user, it’s ready to use as needed where there’s no cell service.

The GoTenna feels sturdy thanks to premium, lightweight materials, and we’re confident it could withstand occasional drops or scuffs. It’s also water resistant enough to be used in the rain.

When you and your partner are ready to use GoTenna, just attach the antennas to your body as high as you can. A backpack strap would be ideal, but you can also strap it to your belt, hat, or just carry it by hand if needed. Then you both pull the antennas out and launch the GoTenna apps on your phones, and it will automatically connect. Now you and your partner can text and share locations. If your phone is in sleep mode, you’ll get notifications on your lock screen and a chime when your partner texts you. As long as you keep your antennas deployed and your phones powered on, you’ll be connected.

Maps of each state and country are available for free download, so you can see exactly where your partner is at without having a cell signal. You can send your location or request your partner’s location. Just tap on the icon shaped like a pin in the GoTenna app and the downloaded map will display you or your partner’s location. The map shows regular features such as roads, terrain, and cities, plus camping spots and hiking trails.

We experienced about the same latency as regular texting with a cell signal, so it’s quick. In our tests, we parted around a mile away and maintained strong signal between GoTennas the entire time. The app works no differently than any other messaging app, and was very intuitive to use. We were pleased with just how reliably everything worked. GoTenna’s app also has other features, like the ability to chat openly to anyone else with a GoTenna within range.

GoTenna can be had for $199 for a pair of antennas, and $389 for a set of four. They’re a lot of fun to use, and a smart way to stay in touch with your group, but more importantly, the GoTenna could quickly become essential should anything go wrong. Lots can happen outdoors, and becoming lost or separated can be dangerous when alone. Being able to stay in touch with your partner outdoors ensures that help is only a text message away.

Yet another study says AI is bad for elections, and the rabbit hole gets worse
AI may be an election bomb waiting for someone to light the fuse
Voters cast their ballots on Election Day

Another election, another study has concluded that asking an AI chatbot for political guidance is a spectacularly bad idea. Research conducted during Hungary’s 2026 parliamentary election found that ChatGPT and Google Gemini offered not just inaccurate but also inconsistent and unreliable voting advice. The chatbots misclassified voter profiles, overlooked relevant parties, recommended parties absent from the ballot, and sometimes produced materially different answers when given the same information repeatedly.

Samsung’s humanoid robot ambitions are real, but factories come first
Samsung’s new robotics division has humanoids in its sights, although its immediate business is far more practical factory automation
Robot Touch Human Finger

Samsung wants a place in the humanoid race, but its new robotics push begins with machines built for factories rather than homes.

The CEO-led RX robotics division will initially focus on manufacturing robots. Samsung has separately identified humanoids as a priority, although it hasn’t announced a commercial model or explained where one fits into the division’s immediate plans.

The future of AI may depend on this one behind-the-scenes change
Running Claude on Android.

Whenever a new AI model arrives, it's easy to get caught up in the bells and whistles. We talk about how much smarter it is, how quickly it answers questions, or how realistic its images have become. But here's the thing: none of that matters much if the AI can't reliably work with the apps and services people use every day.

That's why an upcoming update to the Model Context Protocol (MCP) caught my attention. It isn't a new chatbot or a fancy AI model. In fact, most people will never even know it's happening. But it could quietly make the AI ecosystem a lot healthier. If you've never heard of MCP before, don't worry. Think of it as a shared language that lets AI assistants safely talk to apps like Gmail, Slack, calendars, databases, and countless other services. Instead of every company inventing its own way to make those connections, MCP gives everyone a common rulebook.
