You still get excellent mapping, a durable and premium build, and strong battery life, plus a handful of quality-of-life updates that make daily use even better. Here are the five features on Garmin's latest flagship that I suddenlly find I can't live without.

Apple caught my attention with their claim that the Apple Watch Series 12 and Ultra 4 have the “most accurate heart rate in a wearable.” It’s hard to make a really accurate heart rate sensor, and in my experience, Apple hasn’t had a great track record in that area. So I tested the Series 12 pretty intensively over the past week or so, and now I have results. Apple Watch Series 12 (GPS, 42mm) $399.00 at Amazon Get Deal ...

You need to join a waitlist to try Apple's new and improved chatbot , and since my turn just came up, I put the new on-wrist Siri through its paces. Here's how it went, and why I don't think the experience lives up to Apple's promises (yet, anyway). What devices have Siri AI?  Since Siri AI requires Apple Intelligence, you’ll need a device that supports it. Those include iPhones 15 Pro and newer, and an Apple Watch that is Series 9 or newer. If you want to use Siri AI on the Apple Watch, you need both a supported watch and a supported phone—a new watch and old phone won’t do the trick. With my phone and watch both on iOS 27 (the iOS 27.2 developer beta on the phone; watchOS 27.0 on the Apple Watch Series 12 ), I enabled Siri AI in my phone’s Settings app, which put me on a waiting...

Does the device capture the ups and downs of my heart rate? I even got a VO2max lab test to check a bunch of watches' fitness scores. But one thing I never test for accuracy is calorie burn. None of my devices come close to agreeing on the number of calories they think I'm burning, and I don't expect them to. Even scientists who study the accuracy of wearables can't answer the question in a way that's useful when you're shopping for this year's devices—but we'll get into why that is below. There was a time, before Fitbits, when nobody knew quite how many calories they were burning on a daily basis. Sure, you could calculate a rough estimate based on your body size, sex, and age. You could choose whether or not to believe the calorie readout on the cardio machines at the gym. (You shou...

A VPN conceals your IP address by routing your internet traffic through a remote server, preventing anyone surveilling the network from tracking your online activity. Theoretically, that means no one should be able to identify you when you connect to a network and browse the internet, even your ISP.  In practice, though, there are plenty of gaps that hackers can exploit. A while back, Lifehacker covered browser fingerprinting , which uses hundreds of data points, like your hardware specs, operating system version, web browser, and GPU signature, to establish a shadow profile that follows you around even when your VPN is enabled. There's another way cyberattackers can intercept your data, and it involves exploiting a communication leak right inside your browser.  Major browsers like Chrome, Firefox, and Edge have a feature called WebRTC that lets them bypass the encrypted Transmission Control Protocol (TCP) tunnel created by your VPN to establish high-speed connections for de...

For anyone who wants to level up from a smaller TV without having a screen take over the entire room, 65 inches is the sweet spot; it gives you that cinematic feel for movies and gaming but is still easier to place on a media console or stand than a more massive alternative (that said, the 75-inch model is also 33% off right now).
