Software may include digital maps, schedulers and personal organizers, calculators, and various kinds of watch faces. The watch may communicate with external devices such as sensors, wireless headsets, or a heads-up display. Like other computers, a smartwatch may collect information from internal or external sensors and it may control, or retrieve data from, other instruments or computers. It may support wireless technologies like Bluetooth, Wi-Fi, and GPS. For many purposes, a "watch computer" serves as a front end for a remote system such as a smartphone, communicating with the smartphone using various wireless technologies. Smartwatches are advancing, especially their design, battery capacity, and health-related applications.[5]

Apple Watch Series 3: If you are an iPhone user and generally exist in Apple’s ecosystem, it makes sense to get an Apple Watch. The design quality is exceptional and the Watch makes a nice pairing with your iPhone as materials and design elements are common to both. Apple’s Health app covers most of the bases when it comes to tracking your essential fitness and activity indicators - nutrition, sleep, physical exercise, but Apple has gone further with HealthKit, which allows health and fitness apps downloaded from the App Store to share data with each other. Apple has committed to Watch, and its attention to practical and eye-pleasing design as well as useful tracking features is commendable. ($529)

The SmartWatch 2 is a streamlined version of Sony's first smartwatch (which went on sale in 2013) with a number of new features. The SmartWatch 2 has a thin bezel; it's almost all screen, which gives it a modern, sleek look. You choose from one of two strap designs, black plastic or black stainless steel, or you can swap those out for a leather strap in one of seven colors ($20 each). We tested the model with the plastic strap, which is light and flexible and can fit close to your wrist.

The Charge 3 works continuously throughout the day to track steps, distance, calories, floors climbed, and heart rate—the standard array of activity data. Fitbit has been tracking these metrics for so long, without making many significant updates as of late, that they are business as usual on the Charge 3. I appreciated that most of the watch faces available for the Charge 3 show your real-time heart rate, either in a corner or at the bottom of the rectangular display. I like being able to glance down and know my pulse.


Speaking of music, that's what really sets this smartwatch apart (especially compared to Garmin's other wearables). The Vivoactive 3 Music has enough internal storage for 500 songs — and they're easy to download to your device using the Garmin Express software. Once your songs are downloaded, you can listen to music without a smartphone. Just connect some Bluetooth headphones to the watch and you're good to go. If streaming is more your game, then you can also download some popular media apps as well. 
The RC-1000 Wrist Terminal was the first Seiko model to interface with a computer, and was released in 1984.[10] It was developed by Seiko Epson and was powered by a computer on a chip.[12] It was compatible with most of the popular PCs of that time, including Apple II, II+ and IIe, the Commodore 64, IBM PC, NEC 8201, Tandy Color Computer, Model 1000, 1200, 2000 and TRS-80 Model I, III, 4 and 4p. The RC-20 Wrist Computer was released in 1985, under the joint brand name "Seiko Epson".[13][14] It had a SMC84C00 8-bit Z-80 microprocessor; 8 KB of ROM and 2 KB of RAM. It had applications for scheduling, memos, and world time and a four-function calculator app. The dot-matrix LCD displayed 42×32 pixels, and more importantly, was touch-sensitive. Like the RC-1000, it could be connected to a personal computer, in this case through a proprietary cable. It was also notable in that it could be programmed, although its small display and limited storage severely limited application development.[10] The RC-4000 PC Data graph also released in 1985, was dubbed the "world's smallest computer terminal".[10] It had 2 KB of storage. The RC-4500 (1985), also known as the Wrist Mac, had the same features as the RC-4000, but came in a variety of bright, flashy colors.
The Apple Watch boasts cutting-edge smartwatch tech including mobile payments with Apple Pay, stand-alone GPS, full waterproofing up to 50 meters, and thousands of apps. The user interface is very simple and attractive. It's easy to use and it has advanced, easy-to-use fitness tracking features, thanks to a plethora of sensors and an excellent heart rate monitor.
Fitbit OS 2.0 brings a new-look UI that offers more insights into your daily data and quick reply support for messages for Android phone users (iOS support coming at a later date). You can still download apps and a whole lot of watch faces, pay from your wrist using Fitbit Pay and tap into Fitbit Coach, while new women's health tracking has also been introduced for the first time, which is also available for the Ionic, too.
Smartwatches are still a very new thing to a lot of people, and for good reason. You don’t absolutely need one to get through the day, and some of the best smartwatches are much too expensive for many folks out there. With that said, they are good for a lot of things. They can provide you with an easy way to get information, allow you to dismiss or reply to new messages without having to pull out your phone, and much more.
The TicWatch Pro shares the TicWatch E model’s older processor and late arrival, and it would be just another big (45 mm case), thick (12.6 mm) Android smartwatch, if not for its trick of having an old-fashioned-looking LCD screen that the watch switches to when you’re not actively looking at it or using it. This feature extends battery life significantly, especially if you go for periods in Essential Mode, where you see only the LCD screen showing the time, date, and your step count. But the transition from the LCD screen back to a “smart” OLED screen is not smooth or quick, and if you switch the watch to Essential Mode, you have to reboot it to get back to regular smartwatch functions.

The Apple Watch Series 3 is a really nice smartwatch that does exactly what it should. This is easily one of the best smartwatches on the market. It’ll give you quick access to notifications, allow you to pay with your wrist, give you turn-by-turn directions, and it’s a decent fitness tracker. In terms of design, it doesn’t feel like Apple cut too many corners with the overall look and feel of the device. Even the Sport model (the cheapest one of the bunch) feels like a well-built piece of hardware.

The claim to fame on the Ticwatch Pro is battery life. The Pro offers up to 30 days of battery on a single charge. Of course, that all depends on how you use it. Mobvoi’s trick to improve battery life comes with the addition of a layered screen that acts as two displays. One is designed for use when the watch is idle, only showing crucial information such as the time to sip power. Under that is a standard OLED display that delivers the full Wear OS experience.
That same attractive stainless steel design is here. The 240 x 240 pixel display at the heart of the body is by no means the brightest or most vibrant you'll find, but crucially delivers strong visibility in most workout conditions whether you're sweating it out indoors or outside. However, there is no touchscreen or touchpad here, you'll have to resort to pressing some buttons - that could be a deal-breaker for some, but we're sure it won't be a massive one for most.
I want to purchase a smart watch but ,I no what I want but it has to be compatible to my lg 7 slim ,I want to talk and I want to be able to control my phone thru my watch by talking to watch,I just don’t no what watch is best for me,I’m doing my homework so that I don’t purchase a smart watch that can be better than what I want ,I want the whole package but it has to be a reasonable price,if someone can help me ,I deeply appreciate you’re kindness,thank you KevinElliott,

If you’re trying to decide which one is right for you, allow us to help. The Versa is smaller and looks good on most wrist sizes, while the Ionic is probably best for large wrists. The other main difference is GPS connectivity — the Ionic comes with built-in GPS, while the Versa does not. However, you can pair it with your smartphone if you don’t mind bringing it with you on a run. 
If you don’t need your smartwatch to look business-casual, you want more fitness and exercise features than our top pick, or you’re a Samsung loyalist, the Samsung Gear Sport is a better pick for you. (You can use the Gear Sport with non-Samsung phones, but doing so requires that you install at least four apps.) The Gear Sport handles all the casual notification and message-triage functions of a smartwatch about as well as our top pick—with the exception of voice transcription—but it adds heart-rate monitoring, GPS tracking, swim tracking, and built-in reminders to move throughout the day. It doesn’t do all of these things perfectly, but it does just enough to make for a generally useful smartwatch, with great battery life and a clever interface.
To charge the watch, you have to clip on the charger and align it with contacts that you can't see when you're clipping. Why make it so complicated? There's no NFC for easy pairing, and you have to find the smartwatch app in the app market, download it, and install it on your mobile device. The Frame's display readability in bright sunlight was judged to be only good. It's relatively heavy, at 2.7 ounces (only the Toq is heavier).

On 9 September 2014, Apple Inc. announced its first smartwatch called Apple Watch to be released in early 2015.[75] On 24 April 2015, Apple Watch began shipping across the world.[76] 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,"[77] 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.[78]
Garmin has been putting out go-to smartwatches for sports lovers for a while now. Running, cycling, swimming, golf - Garmin has had us well and truly covered. Despite the Forerunner name, the 645 Music is more in the mould of the Vivoactive 3 Music. It's got a similar look and also brings the music this time. This helps make the Garmin more of a smartwatch rival to the Apple Watch, Samsung Gear or Fitbit Ionic than before.
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 Charge 3's module weighs in at 20 percent lighter than that of the Charge 2, so it won't weigh down your wrist when you're wearing it. I barely noticed it on my wrist when I paired it with Fitbit's woven bands, which are made of a feather-light fabric material. If you're looking for the band that both complements the device's weightlessness and remains fashionably flexible enough to go from the gym to the office, I'd go with a woven option instead of the standard silicone one.

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.
Speaking of music, that's what really sets this smartwatch apart (especially compared to Garmin's other wearables). The Vivoactive 3 Music has enough internal storage for 500 songs — and they're easy to download to your device using the Garmin Express software.

In China, since around 2015, smartwatches have become widely used by schoolchildren. They are advertised on television throughout the country as a safety device whereby the child can call in case of emergency. The devices are commonly colorful and made of plastic. They normally have no display unless a button is pushed. These smartwatches have limited capability compared to other smartwatches; their main functions consist of being able to conduct calls, displaying of time, and sometimes have air temperature sensitivity. They cost around $100 to $200 USD.
Using your voice with the Google Assistant function built into the Q watches (and every modern Wear OS watch) is generally okay, though only roughly 80 percent reliable. The combination of a microphone on the side of your watch, a Bluetooth connection to your phone when you’re away from Wi-Fi, your phone’s cellular Web connection, and the imperfect acknowledgement of human speech by Google Assistant do not make for anything near a 100 percent success rate. When it works, Google Assistant makes you feel connected and advanced; when it fails, you can be seen as a person who asks their wrist about the capital of Malaysia. This is more a reflection of the state of connectivity and digital assistants than of the Q watches themselves—or any Wear OS watch, for that matter—although in our experience Wear OS watches fail on voice queries more often than Siri on the Apple Watch. That said, voice dictation on the Q watches is far more reliable, at least when it comes to recognizing words and phrases, than Google Assistant. If transcription fails, it’s more likely to be because of the watch/phone connection than the watch mishearing your words.
The Moto 360 was the first round smartwatch we got our hands (or wrists) on, and the design was a standout, for us. It looks like a traditional watch and fits more comfortably than rectangular smartwatches, but still packs the full functionality of an advanced smartwatch. Like the LG G Watch and Samsung Gear Live, it runs the Android Wear OS, allowing voice commands and pushing relevant information to the wearer.

The Sport’s built-in fitness features do a decent job of motivating you to move more, tracking a Fitbit-like set of metrics: Stairs climbed, steps taken, and minutes active. It reminds you to get up every hour or so and suggests stretches and movements you can do at your desk if you’re stuck there. While the Sport can track your movement and exercise, and start doing so automatically, it is not accurate enough for dedicated runners or cyclists (who should get a GPS running watch instead): Influential fitness gear tester Ray Maker (aka DC Rainmaker) clocked “the worst GPS track accuracy I’ve ever seen on a run” wearing the Gear Sport. We didn’t see quite the same entirely-different-street discrepancies in biking tests, but the Sport is nevertheless not a competitive training tool, providing only a rough guide to distance and speed.

Finally, Wear OS has a problem that’s seemingly random and hard to understand: “Can’t reach Google at the moment.” Having tested at least a dozen Wear OS watches, we can say that an unexplained failure when using voice commands is the most common negative trait for all of them. It’s impossible for the layperson to understand which part of the watch-to-phone-to-Internet relay is falling down, but it can happen at any time, even right after you’ve used the watch to do something else successfully. When Google Assistant is made the center of Android watches, not being able to reach Google Assistant lowers the value of that watch considerably.

I've been pleased to see swim-tracking trickle down into more affordable devices over the past few years. Fitbit's Flex 2 remains its most affordable device with swim-tracking features, priced at $60. But the $150 Charge 3, with its big display and smattering of smartwatch capabilities, is for a different audience than those who would gravitate to the tiny, quasi-cylindrical Flex 2. Even if you don't swim often, water-resistance up to 50 meters means users don't have to worry about showering with the Charge 3 or dropping it in the pool by accident.
