A healthy boost for athletes

Apple has packed its Series 3 watch with some new fitness features as well, and it stacks up well to Fitbit’s New Ionic watch, with an expanded and enhanced Workout app, and a barometric altimeter designed to measure elevation. Older watches still measure flights climbed, but it’s that much more accurate on Apple Watch Series 3.

The new Heart Rate app isn't just for athletes.

Apple hasn’t actually updated the heart-rate sensor for its Series 3 watch, but it’s extracting a whole lot more out of it. Launch the Heart Rate app, and you’ll get a bunch of new data, including your current beats-per-minute reading as well as your resting rate and walking average. Even as a non-athlete, I found it useful, especially the feature that alerts you to any abnormalities (thankfully I didn’t get to test it, however).

But music is Apple Watch Series 3’s killer new fitness feature. All throughout watchOS 4 there are little touches that make it easier to listen and control your music: You can swipe left in the Workout app to bring up music controls, a Now Playing box appears on the Siri watch face, and the music app will automatically sync playlists while charging. However, you still can’t play music through the Apple Watch’s speaker, and proper LTE streaming won’t arrive until the upcoming 4.1 update.

LTE brings it all together

All of the above upgrades are nice, but Apple Watch Series 3 is all about one thing: its cellular connection. For the first time, an Apple Watch can operate independently of your phone, and it’s a liberating, transcendent experience... most of the time.

The complication on Explorer would be great as an option on other watch faces.

I’ve used a variety of LTE watches from Samsung, LG, and ZTE, and Apple Watch Series 3 is the first that delivers on its promise. Setup with the eSim and my Verizon account was remarkably simple, taking less than a minute, and the only setting to speak of is an on/off toggle. LTE simply takes over when your watch is out of range of your phone. I was very aware of when it was running at first, but after a couple days I stopped obsessively checking to see if my watch was connected.

It’s not perfect, however. I didn’t have anywhere near the constant problems with unauthenticated networks that some early reviewers experienced, but there were still instances where my watch showed a red “x” while roaming to indicate that it was disconnected from the cellular network. Resetting my phone’s network settings and deleting some old saved networks my Mac helped immensely, but that’s not something you should have to do to ensure a stable connection. Apple issued the 4.0.1 update while writing this review to correct it, but it didn't fix some of my other occasional problems.

In poor coverage areas, I found that the watch routinely dropped its connection where my phone was able to hang on with a bar or two. If I was on a call when I left my house, it consistently dropped when switching from Wi-Fi to cellular. And once it required a hard reset to get LTE going on my watch again again.

In strong coverage areas, however, my watch worked great. Overall my issues were infrequent and as expected for a first-gen product. I did want the ability to add a cellular complication to any watch face. The antenna isn't nearly as strong as it is on the iPhone, and unless you’re using the Explorer face, you can’t quickly tell how strong your connection is without heading into the mini Control Center first. I'm hoping this is a new feature in watchOS 4.1, along with a fix for my Wi-Fi handoff issues.

When you walk away from your phone with an LTE Apple Watch, you don't need to freak out anymore.

But even with the above hiccups, LTE on Apple Watch Series 3 is game-changing. I routinely left my phone on the charger while leaving the house for quick errands or to pick up my son from school, and my watch dutifully kept me up-to-date with notifications. I never missed a message, call, score, or breaking news brief, and Siri’s improved responsiveness let me quickly send messages over LTE without needing to scribble letters on the screen. And at times, my watch actually refreshed faster than when it was tethered to my phone. 

watchOS still a work in progress

Just because you can use Apple Watch without your phone doesn’t make it an iPhone replacement. Even with watchOS 4, many third-party apps still depend on the phone for data retrieval, and things like checking my Twitter timeline, controlling my Hue lights, or peeking at my Ring video doorbell feed just weren’t possible. Developers have slowly been moving away from building Apple Watch apps—just last week Twitter disappeared from the store, and I had major issues with it even before that happened—but I’m hopeful LTE compels them to get back on board.

Android Wear 2.0's Play Store is something Apple might want to borrow for watchOS 5.

And here’s something that would help spur interest: an on-watch App Store. It’s one of the best features of Android Wear 2.0, and it would be awesome to quickly find and install a watch app while away from our phones. Also missing is a stock Notes app. While there are a few third-party options, I wanted a way to quickly ask Siri to take a note and have it sync back to my iPhone. As it stands, that can’t happen.

I love having a list view for apps—seriously, I’m never using the honeycomb screen ever again—but the new Dock isn’t as great. It’s basically a task manager/app switcher, and I much preferred the original Glances or watchOS 3’s snapshots, which would let you get little bits of info without actually opening the app. With the new method, apps need to be launched before they’re updated, like the iPhone’s app switcher. Fast app switching isn’t nearly as useful on the watch as it is on the phone, and I’d like to see Apple revert to the old version in watch OS 5. Glanceability is important, and it’s not really there in watchOS 4.

Say goodbye to the honeycomb screen forever with watchOS 4's list option.

My favorite new watch face on watch OS 4 was already the Siri one (sorry Buzz and Woody), but Apple Watch Series 3 takes it to a new level. With LTE connectivity, the Siri face is even more useful when my phone’s not around, as it continuously shows a stream of news, weather, stocks, and photos. LTE and the Siri face didn’t seem to have a noticeable impact on battery life. Third-party app support would make the Siri face that much better, but something tells me we’ll have to wait a while before that arrives.

But mostly watchOS is merely a step, not a leap, forward. There are still occasional bugs. For example, I couldn’t take a screenshot despite toggling, restarting, and re-pairing, and the side button is less useful than ever. But you’re still not going to find a better wearable platform.

Should you buy an Apple Watch Series 3?

For my purposes, Apple Watch Series 3 is a software update and a couple apps away from being my dream device. But even in its current form, it’s miles ahead of its closest competitor when it comes to functionality and parsecs ahead with design. There’s a reason Apple hasn’t visually changed its watch in three generations: It’s nearly perfect.

Even from far away, the Digital Crown's red dot will tell everyone you're special.

You can quibble over price, but it’s a bit like comparing a Casio watch to a Tag Heuer or a Rolex. You can save a few bucks by getting a cheaper Android Wear or Fitbit watch, but you’ll definitely get your money’s worth by choosing an Apple Watch Series 3. At $329/$359 for the GPS model or $399/$429 for LTE, it’s hardly a luxury item anymore. Granted, you can spend $1,200 on a ceramic Edition or Hermès double tour, but the affordable entry-level sport models look and act just as good.

Apple is the only company committed to developing a solid wearable platform. Fitbit’s Ionic is initially underwhelming as a smartwatch, Samsung’s Tizen OS is still struggling with security and adoption, and we’ve yet to see a meaningful Android Wear 2.0 watch after six months of public availability. LTE has its issues—most of which will be snuffed out in the first software update—but Apple Watch Series 3 with LTE is the first cellular smartwatch to get it right. Apple Watch Series 3 might not be an iPhone replacement, but it’s the closest thing to an all-day, independent wearable you’re likely to find.

And it’s the best remedy for Forgotten Phone Anxiety.
