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]
"Sport watch" functionality often includes activity tracker features (also known as "fitness tracker") as seen in GPS watches made for training, diving, and outdoor sports. Functions may include training programs (such as intervals), lap times, speed display, GPS tracking unit, Route tracking, dive computer, heart rate monitor compatibility, Cadence sensor compatibility, and compatibility with sport transitions (as in triathlons). Other watches can cooperate with an app in a smartphone to carry out their functions. They are paired usually by Bluetooth with a smartphone. Some of these only work with a phone that runs the same mobile operating system; others use a unique watch OS, or otherwise are able to work with most smartphones. Paired, the watch may function as a remote to the phone. This allows the watch to display data such as calls, SMS messages, emails, calendar invites, and any data that may be made available by relevant phone apps. Some fitness tracker watches give users reports on the number of kilometers they walked, hours they slept, and so on.
The headline features are the new ECG monitor that unlocks the ability for serious heart health monitoring. It's been FDA cleared, so the feature can be used to detect heart rhythm irregularities - however, it's only in the US only for now. There's also a new fall detection mode that can let users access Siri to contact emergency services or a emergency contact. Apple's new smartwatch offers groundbreaking features and an improved design that makes it the standout option for iPhone owners right now.
I go for a middle-of-the-road approach—I enable alerts for most of my installed apps, save for ones that are niche (mostly shopping apps that alert me to coupons) or ones I don't use regularly. All alerts make the Charge 3 vibrate and show the message on its screen, and all past alerts live in the notification drawer that you can access by swiping down from the top of the Charge 3's display.
Next is the big focus on health and fitness. The Apple Watch can monitor your heart rhythm and suggest you see a doctor if it detects something irregular, it can call the emergency services you've fallen over, and it will keep you healthy by tracking your run. These potentially life saving features are a major reason people are ditching their traditional watches for an Apple Watch.
No other smartwatch offers this much variety and customization, especially when it comes to female-friendly options. The Apple Watch is the only smartwatch I've ever worn regularly each day for months on end. I've reviewed dozens of WearOS watches, and although many of them are nice looking as well, they're not as fully featured or easy to use as the Apple Watch.
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,
The hardware is now “swimproof” with improved water resistance and there’s also now a heart rate sensor. Those work with the new Google Fit app to improve the fitness experience from your watch. Further, the Falster 2 has built-in GPS and NFC as well. This opens up Google Pay functionality for the watch for mobile payments in-store. Of course, Wear OS is still at the center of the experience, and the whole thing runs on the Qualcomm Snapdragon Wear 2100.

The Series 4 now has several new health-focused features, which are very intriguing, including the ability to detect when you fall and even alert emergency contacts if need be, as well as an electrical heart rate sensor that works with an app to alert you to heart health issues. The electrocardiogram (ECG) app has been certified by the Food & Drug Administration, but it's not out yet.

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]

We actually got our hands on over a dozen of these smart watches just to get a feel for what it was like to use them. While all of them came with at least one main button (or a home button if you’re an iPhone-user), the ones that stood out had scrolling down to a science. On such a small screen, swiping isn’t always the most ideal form of navigation. Some of the best smart watches for navigation, we found, had twistable dials or bezels you could turn.
