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)
As of 4 September 2013, three new smartwatches have been launched: the Samsung Galaxy Gear, Sony SmartWatch 2,[62] and the Qualcomm Toq.[63] PHTL, a company based in Dallas, Texas, completed is crowd-funding process on Kickstarter for its HOT Watch smartwatch in September 2013. This device enables users to leave their handsets in their pockets, since it has a speaker for phone calls in both quiet and noisy environments.[64] In a September 2013 interview, Pebble founder Eric Migicovsky stated that his company was not interested in any acquisition offers,[65] but revealed in a November 2013 interview, that his company has sold 190,000 smartwatches, the majority of which were sold after its Kickstarter campaign closed.[60]

Waterproof to 165 feet, the Versa handles swimming as well as any other exercise, with the screen surprisingly visible underwater. As is standard with many other non-smartwatch Fitbit models, heart rate tracking is built in, which allows for detailed sleep tracking. There’s no GPS, though — if you want to track your running route, you’ll need to carry your phone or pay the extra for the Ionic model.
Bottom line: If health and fitness tracking is your priority, opt for a dedicated fitness tracker that gives you basic time and date information but includes the essentials of health tracking - accelerometer and altimeter, heart rate monitor and GPS chip to track distance and location. Carefully consider your exercise habits to match them to the right fitness tracker.
While internal hardware varies, most have an electronic visual display, either backlit LCD or OLED or Hologram.[4] Some use transflective or electronic paper, to consume less power. Most have a rechargeable battery. Peripheral devices may include digital cameras, thermometers, accelerometers, pedometers, heart rate monitors, altimeters, barometers, compasses, GPS receivers, tiny speakers, and SD cards, which are recognized as storage devices by many other kinds of computers.
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.
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. 

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.
Built-in GPS and a great workout coach make the Huawei Watch 2 a great companion on long runs and intense workouts. You can leave your phone behind, too, thanks to onboard music storage and the ability to connect Bluetooth headphones to the watch. Like the LG Watch Sport, the Huawei Watch 2 has an LTE version, but unfortunately, Huawei isn't selling that model in the US yet.
We pulled together a list of currently available smart watches that met these criteria from Apple, Android Wear, and Samsung. Our list included watches from tech brands like Apple, Asus, and Samsung, as well as fashion labels like Fossil, Nixon, and Tag Heuer. Then, we cross-checked with respected review sites, such as Tech Radar and PCMag, as well as tech retailer Best Buy, to make sure we weren’t leaving out any hidden gems.
