Samsung Gear S review: The smartwatch that's also a smartphone

It makes phone calls even when it's away from your phone, but Samsung's big, curved, new smartwatch doesn't do all the magical things we'd hoped for.

The dream of a fully standalone wrist gadget that can make phone calls, stay connected and even help you be sounds good, at least on paper. To own a smartwatch usually means having it be perma-paired to a phone in your pocket: it ends up being, largely, a phone accessory. That's starting to change. A few bold watches are trying to break away and be their own devices, with their own phone service to boot.


Samsung Gear S

The Good

The Samsung Gear S has a big, bright curved display, decent battery life, comes with its own bonus battery pack and can stay connected away from a phone with its own 3G data or Wi-Fi. It's attractive, albeit rather large. It's a complete on-wrist phone.

The Bad

It still requires a recent Samsung phone to pair with and install apps, and its standalone features don't work with all apps and notifications. The Gear app library is still weak compared with Android Wear.

The Bottom Line

The wildly ambitious Samsung Gear S smartwatch doubles as a full standalone smartphone, but the software and apps available don't let it do as much as you'd expect.

The Samsung Gear S is one of those. This is Samsung's sixth smartwatch in a little over a year, but it has one big difference: it gets its own cell service and data. It even has its own SIM-card slot. It's a watch that's also a phone.

Someday soon, smartwatches might be devices that work totally on their own, no phone necessary: as a connected Web browser, a music player, a fitness device. But the Samsung Gear S is not exactly that magic watch. Yes, it can do a surprising number of things. But it still needs a Samsung phone to make most features work. It runs Samsung's limited Tizen software and dedicated Gear apps, closing it off from the richer ecosystem of Google's Android Wear. And it requires a connected data plan to even use it as a cellular device.

For some of my time with the Gear S, I paired it with a Samsung phone. But for most of the time, I tried using it on its own, as a true independent smartwatch. Well, I should say "independent," because if you're going to use a Gear S, you're still best off bringing a phone along.

The Gear S looks like a little smartphone that's been melted around a wristband. It has a huge, curved screen, chromed edges, and even has a little home button below the display. My 6-year-old son thought I was wearing a phone. Basically, I am.

Remember the Samsung Gear Fit, that little curved-screen fitness smartwatch that instantly caught people's attention just six months ago? Imagine that in a mega-large watch form, and you have the Gear S. Is it too big? For many, the answer's yes. The massive curved display engulfed even my large, thick wrist. But many people, including my wife, thought it was one of the better-looking smartwatches I've worn recently. Chromed edges and that huge, bright OLED curved touchscreen make it stand out, and even give it a kind of spiritual similarity to the upcoming Apple Watch Sport.

The rubbery-plastic sport-type band it comes with can pop out around the Gear S central unit and be replaced with another band accessory. It snaps on like previous Gear watches: an adjustable watch band with a clip, it sizes and fits easily.

The watch is IP67-rated water-resistant, which means you can get it wet, but you're not meant to shower or swim with it. It's about the same story as Samsung's previous Gear watches.

The Gear S has its own speakers and microphone. It vibrates when you get messages or an alarm goes off. It's studded with sensors: accelerometer, gyroscope and compass, optical heart rate, ambient light for screen brightness, UV and barometer. It has Wi-Fi, Bluetooth 4.1 and 3G cellular. It's got 4GB of storage, 512MB of RAM and a dual-core processor. And it weighs 66 grams (2.3 ounces). But its display is the most impressive part...and, to some degree, the most alienating.

The phablet of watch displays

The Gear S has a 2-inch 480x360-pixel AMOLED display, a bigger screen and a larger pixel count than other Android Wear smartwatches and previous Samsung Gears. It's longer, almost feeling like a mini-phone in portrait mode.

As always, Samsung's OLED displays look eye-bleedingly vivid and colorful, and in ambient mode time and other notifications glow at just the right gentle level. But the extra screen space means that existing Samsung Gear apps, which run on the Gear S, end up with extra space that sometimes means stretched apps, and sometimes means funky letterboxing. Other apps are optimized for the whole display.

It's plenty of room. Swiping and even two-finger pinching and zooming feels weird. The big curved screen makes vertical scrolling easy, but it ends up being a lot of finger wiggling for many apps, and the Gear S interface doesn't always seem to know what to do with all that space. But it's massive enough to make reading whole articles actually feasible. My favorite app, News Briefing, shows blog headlines and brings up stories to flick and read on the Gear S. I actually used it, from time to time, instead of pulling out my phone.

It's such a cool experience that I wish more apps took advantage of the Gear S extra-large display. Unfortunately, in the Gear App Store, there are few that do.

The problem with typing on a watch

To interact with apps, like a full-fledged Opera Web browser that can run on the Gear S, you can use either a pop-up QWERTY keyboard or voice recognition. The pop-up keyboard is pretty absurd: it's hard to find and type on a tiny screen with one finger. But voice recognition works; it's not as good as Android Wear's voice-based entry, but it's better than S-Voice on previous Gears.

Holding down the center button or pressing the microphone icon on the keyboard triggers voice, and I got it to understand what I was saying, generally. But it's still a huge pain to enter text or long messages on the Gear S, and there doesn't seem to be a plan for installing third-party keyboards or other input options.

Standalone smartwatch...almost

You need to pay for a phone/data package to use the Gear S standalone features, but they are fun to play with. The Gear S packs Bluetooth 4.0, 802.11 b/g/n Wi-Fi and multiband cellular: 3G, but not 4G LTE. You can keep the Gear S perpetually paired with your Samsung phone and use it as a connected accessory, like Android Wear, or you can completely decouple and use the Gear S with nothing else at all.

On its own, the Gear S felt like...well, a smartwatch. But without notifications. All the coolest pop-up notifications you'd expect, like Twitter, Facebook and other stuff you'd get on your phone, won't show up. Texts and phone calls, yes, but you won't get them from your other phone that's not with you unless you've set up some type of forwarding.

There are some pretty cool things the Gear S can do all on its own with no paired phone...assuming you've paid for a connected data plan. Incoming calls can be answered via a built-in speakerphone, or via a connected Bluetooth headset. I don't like using a speakerphone to make calls on a watch, but there are people that love how Samsung Gear watches can be used for hands-free calling -- something Android Wear watches don't do at all. That this Gear S can do it on its own might be a killer feature for a limited few. I successfully paired the Moto Hint , which was really weird and kind of cool. Suddenly, I was taking a call from something nearly invisible in my ear, made from a watch on my hand.

I found call quality mixed; it might have been a combination of Sprint service dropping to one bar in my Manhattan office, and the Bluetooth headset's mixed success at carrying audio from the watch. Contacts can sync automatically if you set it up in the Gear's Samsung app, or you can finger-dial from the touchscreen, which isn't easy. It made me want to reach for a regular phone.

The other problem here, the one that the Gear S suffers from most, is its Tizen-based Gear app ecosystem. Because -- guess what? -- you need those to actually make the watch do interesting things. Not only does the Gear App marketplace lack many heavy hitters, but few of those apps take advantage of cellular data in a meaningful way. There are some winners. Milk Music streams music to the Gear S, and has a decent interface, so I called up 1940s jazz on my wrist while playing with my son. The Nike+ running app works as a pretty good stand-alone fitness tracker, too, and syncs to the cloud with your Nike account, turning the Gear S into a GPS running watch. But to download and manage these apps, you still need to connect via your Samsung phone.

Gear apps: Lots of them, and yet it feels barren

There's a distinctly "Inception"-like feeling to launching a phone app that invites you to browse a store of even more apps for your watch. Google's Android Wear ducks the confusion by enabling apps to cross-load on your phone and watch, but the Gear S needs its own microstore. Unlike the Pebble, which has apps that are all basically free, Gear apps can cost a dollar, or even two or three.

I browsed the selection, and while there are tons of apps, they're not ones that anyone would recognize or even want. There are games, camera remotes, watch faces and novelty apps galore, but no Twitter or Facebook apps, no helpful sports-score apps, or travel apps of any known quantity. Browsing "Finance" in the Gear App Store brought up calculators, loan calculators and currency converters. Under "Fitness" I found Runtastic, but not much else I could recognize...just a lot of random and frequently not-free fitness apps. "Social Networking" featured an SOS Emergency App, a phone camera remote and the game Tilt 2048, but nothing from any social network I've ever used.

The best Gear apps are the ones that come pre-installed: Milk, Samsung's streaming-music app, Nike+, and that News-briefing reader app.

If Samsung ever wants Gears to become fantastic smartwatches, Gear watches need to either run better apps or be fluidly connected to Android phones and their features. Right now, they're neither...and the Gear apps don't look like they'll be improving anytime soon.

Striving for fitness

The Gear S has a built-in suite of fitness apps that are better, in concept, than anything on previous Gear watches or bands. A dashboard shows steps taken, minutes exercised, recent heart rate and hours slept the night before or even UV data; this watch has a UV sensor much like the Microsoft Band, but needs to measure daylight manually.

You can enter dedicated walking, running, hiking or cycling sessions, which track heart rate and distance, and maps your journey via GPS if the Gear S or your phone can lock in a signal. Charts and logs are kept on the watch. It's a better-presented fitness app suite than what was on the last set of Gears.

But Samsung's optical heart-rate sensor on the back, while getting and locking onto my heart rate better than previous Gears, was still all over the map on accuracy. During one brisk walk my heart rate logged at an impossibly high 171bpm.

There are other fitness apps that run on the Gear S, too. The best, and most exciting, is Nike+. It looks good, has a clean, energetic interface and hey, it's connected to Nike+ and the Fuel ecosystem. It's a dream pairing for Samsung and the Gear S. It starts and ends runs, acts as a remote to play music you want to run to and shows stats, tracks runs via GPS when you're using your cellular data service, and syncs your progress. It's a bit pared-down, but with a few more known-quantity fitness apps like these, the Gear S could really shine.

Price: Are you ready for monthly charges on a watch?

Because the Gear S is its own phone, you can buy it off-contract, or "on-contract," which means you're agreeing to make it part of a mobile sharing plan, generally for two years.

From there, it's a whirlwind of confusing pricing schemes. On AT&T, the Gear S is the most affordable: $299 off-contract, or $199 on-contract, where you'll pay at $10 extra a month to share your mobile calling and data, just like you would on a family plan.

On Verizon, the Gear S costs a whopping $399, or $349 on a 2-year contract (you can tie it into your "More Everything" plan for $5 a month). On Sprint, our review unit's carrier, it costs $384, and doesn't require a contract. On T-Mobile, it costs $350 without a contract.

The point being, pick your carrier and plan wisely: the true cost of the Samsung Gear S varies greatly and depends on what you're tying it to.

It's simpler in the UK, but no better value. It's exclusive to O2, which is selling it on a variety of expensive contracts. You can pay £380 up front and then £8 per momnth for a miserly 100 minutes of calls and 100MB of data; or pay £10 upfront and £23 for the same deal.

In Australia, the Gear S costs AU$449 off-contract, with local telcos yet to announce specific deals. You'll still need a separate SIM card and contract though.

The 300mAh battery on the Gear S runs down quickly if you're using it as a phone. I didn't even power-use it much, but found it lasted about one full day. With 3G off, the Gear S did better, making it through a couple of days...a little better than other Android Wear and Samsung Gear watches.

Samsung did think ahead here: an included Micro-USB wall charger fits into a clip-on dongle that charges the Gear S, and the dongle snaps off to become its own 350mAh battery. When the Gear S runs low on batteries, you can clip on the battery pack for a recharge. You can't wear it with the battery on, but it saves a trip to an outlet. It's better than not having it, and it's included in the box.

What would be cooler, of course, would be if the Gear S was able to last even longer on a charge. But battery life isn't really where the Gear S fails.

Most people can't even be motivated to buy one smartwatch; Samsung's Gear S asks you not just to buy into a completely isolated world of Gear apps that only work with Samsung phones, but it's designed with its own SIM card and optional data plan. Would you pay an extra $10 a month (or your local equivalent) for standalone data on your watch? No, I didn't think so. And the Gear S doesn't even do a good job convincing anyone why you'd want a standalone smartwatch in the first place, because when it comes to being always connected, this Gear S just isn't that smart. It has moments of brilliance, but it isn't as fluidly awesome as you'd expect a soup-to-nuts phone/watch running apps could be.

It's a shame, because Samsung is clearly making impressive hardware, and the Gear S is a feat of miniature gadget design. The Samsung Gear S is actually a crazy and oddly bold bit of tech. It's wildly more ambitious in spirit than Android Wear watches, can do things you've probably never done on a watch before, and it looks somewhat attractive, if gigantic. It's Samsung's best Gear watch to date. But at this point, and at this price, the Gear S isn't enough. And, in the months to come, it'll do far less than Android Wear watches will. So, if you have a Samsung phone, why not just invest in an Android Wear watch?

The Gear S isn't necessary, some of its features just don't work well, and it's got way too few actually useful apps. And I doubt its app environment will ever get better with Apple and Google ramping up efforts next year. But at least credit Samsung for trying to break new ground and explore new ideas. The Gear S feels more like a wearable concept car than a fully baked killer gadget, and it's breaking some exciting new ground for wrist wearables. Whether it ever becomes more than that depends on how fast Samsung's seventh smartwatch comes along.
