Basically, smartwatches are wearable-technology devices that maintain a relatively persistent wireless connection to your mobile device—usually a smart phone—and can receive notifications of incoming calls, texts, instant messages, social-network updates, and more, from that device. Some can also let you accept and conduct phone calls right on the watch. And even newer models (the Samsung Gear S, for one) can act as smart phones all on their own, without needing a paired phone nearby.
Finding and installing apps is another sore point. Android Wear 2.0 has two ways of installing apps: On the watch directly, which is woefully awkward, or through the Play Store on the Web, which is okay. Watch faces for Wear OS exist in the kind of state Android phone apps were in during their earliest days—all over the place, so good luck searching. Watch makers would do well to include some sensible, category-spanning offerings by default in their devices.
Yes, it can monitor your health and fitness. You should choose one that has a pedometer to count your steps. An accelerometer is helpful in determining acceleration. Acceleration can be used to detect when you fall. A heart rate sensor can be used to monitor your heart beats. Some will report the amount of calories you consume and even display a report of your health at day’s end.
Smartwatches, like smart phones, can also run apps, via your smart phone or right on the watch. These include health and fitness apps (thus the comparison with activity trackers), apps that control functions such as music and the camera on your phone, navigation apps, and more. Because most smartwatches have open software platforms (at least so far), developers are coming up with new and innovative apps that can increase the functionality of the devices.
Smartwatches are still a relatively new electronics category, but these devices are poised to hit the mainstream. This year we saw major players such as LG and Motorola throw their smartwatches in the ring, along with Samsung, Sony, and a host of smaller companies like Pebble and Martian. And Apple finally confirmed its entry, the innovative Apple Watch, expected to arrive early in 2015.
On 9 September 2014, Apple Inc. announced its first smartwatch called Apple Watch to be released in early 2015. On 24 April 2015, Apple Watch began shipping across the world. Apple’s first try into wearable technology was met with considerable criticism during the pre-launch period, with many early technology reviews citing issues with battery life and hardware malfunctions. However, others praised Apple for creating a potentially fashionable device that can compete with "traditional watches," not just the smartwatch industry in general. The watch only turns on when activated (either by lifting one's wrist, touching the screen, or pressing a button). On 29 October 2014, Microsoft announced the Microsoft Band, a smart fitness tracker and the company's first venture into wrist-worn devices since SPOT (Smart Personal Objects Technology) a decade earlier. The Microsoft Band was released at $199 the following day, on 30 October 2014.
Inside the Charge 3 are an accelerometer, gyroscope, optical heart rate monitor, and an SpO2 sensor for tracking blood oxygen levels. The Charge 3 is the third Fitbit device to include an SpO2 sensor, following in the footsteps of both the Fitbit Ionic and the Versa smartwatches. However, currently the SpO2 monitor lies dormant inside all of these devices as Fitbit hasn't made use of it yet.
Samsung’s Gear Sport is not as stylish as Fossil’s Q watches, and because it runs Samsung’s Tizen operating system instead of Wear OS, it has nowhere near the app support of Wear OS. But as a smartwatch that shows your phone notifications and lets you respond to them, lasts all day, and tracks your recreational workouts, it is a great device. It’s not meant for competitive speed training, but it has built-in GPS and heart-rate sensing, offline Spotify storage, and a rotating bezel that’s much easier to use while exercising than a touchscreen. It does suffer from weak voice transcription and a barely-there S Voice “assistant,” but it fits a lot of core smartwatch functions into a relatively smart-looking package that’s better for fitness-minded wearers than our top picks.
But smartwatches have the innovation advantage these days as most companies making such devices try to develop features that competitors don't have. As a result, fitness trackers have become a bit stale. And after wearing the new Charge 3 for nearly two weeks to see how well Fitbit's gentle marriage of smartwatch and tracker features turned out, it seems the form factor remains radically unchanged—but that's not a bad thing in practice.
The Samsung Gear Live is the first of the company’s smartwatches to be compatible with any Android phone running Android 4.3 or higher; other Gear models can be paired only with specific Samsung phones. Like the LG G Watch and Moto 360, it runs the Android Wear OS, allowing voice commands and pushing relevant information to the wearer. Compared with the LG G Watch, we prefer the style and fit of the Gear Live. The watch body is slightly curved, which made it more comfortable. The Gear Live also has a heart-rate monitor, which the G Watch lacks.
In 1998, Steve Mann invented, designed, and built the world's first Linux wristwatch, which he presented at IEEE ISSCC2000 on 7 February 2000, where he was named "the father of wearable computing". See also Linux Journal, where Mann's Linux wristwatch appeared on the cover and was the feature article of LJ Issue 75. Seiko launched the Ruputer in Japan - a wristwatch computer with a 3.6 MHz processor. It was not very successful, since instead of a touchscreen it used a joystick-like device to input characters (much like high scores in arcade games), and the small screen with a resolution at 102x64 in 4 greyscales made it hard to read large amounts of text. Outside of Japan, this watch was distributed as the Matsucom onHand PC. Despite the rather low demand, the Matsucom onHand PC was distributed until 2006, making it a smartwatch with a rather long life cycle. Ruputer and onHand PC applications are 100% compatible. This watch is sometimes considered the first smartwatch since it was the first watch to offer graphics display (albeit monochrome) and many 3rd party applications (mostly homebrew).
Of the scores of Wear OS by Google (also called Wear OS, and formerly Android Wear) smartwatches that function nearly the same, the Fossil Q Explorist and Fossil Q Venture are the ones we recommend for most people. Similar models that differ mainly in size and design, these two Fossil watches offer style and band options for the widest range of tastes while performing as well as (or better than) anything else out there. They handle notifications and your responses without delay, provide all-day battery life, swiftly handle voice transcription and Google Assistant questions, and provide casual fitness tracking. Their buttons and screens are responsive. They look and feel like good watches, too, which is something we think most people want from a smartwatch at this point.
The touchscreen, button, and dial (what Apple calls the “crown”) help you zoom in and out and move between apps fairly effortlessly. With this easy navigation it’s easy to forget we’re typing on a screen slightly smaller than an Oreo. In particular, we loved Apple’s app homepage, which displays all of the apps as icons in a honeycomb-like display. You can use the touchscreen to move around, and the dial to zoom in or pan out, to precisely tap on the one you want.
