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]
Dealing with notifications on a Wear OS watch has gotten better as the phone version of Android has improved its already impressive notification system and as phone app developers have taken advantage of new interactions. Many apps now send notifications with action options: For example, you can check a to-do as done, approve a payment, respond to a message, or, most often, just acknowledge something. The Q Explorist and Venture are no different than most Wear OS watches in relaying notifications, but in our testing they rarely showed lag in processing them, nor was either watch’s screen unresponsive to swiping or tapping options. Each watch’s vibration motor provides just enough buzz and movement to avoid missing things while not feeling like electric collar training for humans.
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]
Pebble (watch) was an innovative smartwatch that raised the most money at the time on Kickstarter reaching $10.3 Million between April 12 and May 18, 2012. The watch has a 32-millimetre (1.26 in) 144 × 168 pixel black and white memory LCD using an ultra low-power "transflective LCD" manufactured by Sharp with a backlight, a vibrating motor, a magnetometer, ambient light sensors, and a three-axis accelerometer.[47][48][49][50][51] It can communicate with an Android or iOS device using both Bluetooth 2.1 and Bluetooth 4.0 (Bluetooth Low Energy) using Stonestreet One's Bluetopia+MFi software stack.[52] Bluetooth 4.0 with low energy (LE) support was not initially enabled, but a firmware update in November 2013 enabled it.[53] The watch is charged using a modified USB-cable that attaches magnetically to the watch to maintain water resistance capability.[49] The battery was reported in April 2012 to last seven days.[54] Based on feedback from Kickstarter backers, the developers added water-resistance to the list of features.[55] The Pebble has a waterproof rating of 5 atm, which means it can be submerged down to 40 metres (130 ft) and has been tested in both fresh and salt water, allowing one to shower, dive or swim while wearing the watch.[56]
Why we like it: Garmin’s Vívosport fitness band gives you more (and more-accurate) fitness tracking features than a smartwatch, though you won’t be able to respond to messages and notifications or use apps on your wrist. The Vívosport lasts up to a week on a single battery charge, while an Apple Watch or Android Wear device requires overnight charging. Its screen always shows stats during a workout, while smartwatches like the Apple Watch typically turn off when you’re not looking at them. And you can wear a Vívosport while you sleep to get at least a rough view of how restful your night was without having to worry about charging it every morning. All these things give you a better overall picture of how active and healthy you are, and make it more convenient to wear one smaller device all the time: You won’t have to grab a phone to track a run, you won’t have to wear a large, utilitarian-looking GPS watch to work, and you’ll rarely have to worry about battery life during a long workout. The Vívosport also tracks heart rates and GPS location nearly as well as a GPS watch (with some exceptions), but in a smaller and less noticeable package.

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.


Why we like it: Compared with a smartwatch or fitness tracker, a dedicated GPS running watch is focused on one category of exercise: outdoor movement. GPS watches offer the fastest GPS signal lock-on and more-precise maps, while also showing up to the second details on your pace, heart rate, mile split times, and a host of other stats on an always-on display. The physical buttons on a GPS watch are easier to use while moving (and without looking), rather than having to swipe or tap on a tiny glass screen. A GPS watch’s longer battery life can better handle endurance events than a smartwatch. And the software and apps behind a good GPS watch provide more statistics and training programs to improve your efficiency. While GPS watches can show notifications, the weather, and a few other smartwatch-like conveniences, they’re much more limited in what can be done from a wrist than a smartwatch—or even a fitness tracker like the Vívosmart.

The Apple Watch Series 4 is now on sale, and it's the best smartwatch you can buy right now. The redesigned device, which starts at $399 for the GPS model and $499 for the cellular version, is the best smartwatch you can buy. It has a larger display and slightly bigger case size while retaining the same rounded square design the watch is known for. Even more importantly, Apple received FDA clearance for a new electrocardiogram feature that can take a 30-second EKG and diagnose atrial fibrillation.
