i-watch

          Apple Watch is a line of smart-watches designed, developed, and marketed by Apple Inc. It incorporates fitness tracking and health-oriented capabilities with integration with iOS and other Apple products and services.

          The Apple Watch was released on April 24, 2015 and it became the best-selling wearable device  in the second quarter of the 2015

         The second generation of Apple Watches were released in two tiers in September 2016: the Apple Watch Series 1 and Apple Watch Series 2, while the first generation was discontinued.

      The Apple Watch Series 3 was released on September 22, 2017 alongside the discontinuation of the Apple Watch Series 2. Apple still produces the second-generation Series 1 Apple Watch as an entry-level device.

  


         The main goal is to enhance the uses of an iPhone and also providing the user with some additional new features. Kevin  was hired by Apple to make wearable technology for the wrist. He said: "People are carrying their phones with them and looking at the screen so much. People want that level of engagement. But how do we provide it in a way that's a little more human, a little more in the moment when you’re with somebody?" Apple's development process was held very much under wraps until a wired article revealed how some internal design decisions were made.

     Track and share your activity.

       Stand, Move and Exercise rings visualise the ways you move each day. See if you’re sitting too much. Measure calories burnt. And see how many minutes of exercise you’ve done. You can even share your rings with friends. New smart coaching features and monthly challenges can help inspire you to hit your goals.

          Apple Watch tracks the active calories you burn. Active calories are the ones you burn through all kinds of movement, from taking the stairs at work to playing with the kids to cleaning out the garage. Being active throughout the day is an important part of living a healthy life.


 

  Measure your workouts.

         Pick from a variety of indoor and outdoor workouts — from cycling and running to high-intensity interval training and rowing — then tap and go. Every movement is accurately measured. And Apple Watch pairs with enabled gym equipment.^* So all your stats stay in sync.

       Monitor your health

Since Apple Watch is always with you, it can help you be more aware of your overall health, better manage stress and check your heart rate in more insightful ways. Now you can get daily summaries of your resting, walking and workout recovery heart rate

Dual-core processor

With its dual-core processor, Apple Watch is ready when you are. Your favorite apps launch immediately and are always up to date, so you can perform everyday tasks like viewing your Activity rings, checking your calendar or replying to a message in an instant.

SmartWatches

      It is a wearable computer  in the form of a wristwatch.

        Some smart-watches function as portable media players with FM radio  and playback of digital audio and video files via a Bluetooth or USB headset. Some models, called 'watch phones' (or vice versa), have complete functionality of a typical smart-phone.

        

     Many smartwatch models manufactured in the 2010s are completely functional as standalone products.Some serve as being used in sports, the GPS tracking unit being used to record historical data. For example, after a workout, data can be uploaded onto a computer or online to create a log of activities for analysis or sharing. Some watches can serve as full GPS watches, displaying maps and current coordinates, and recording tracks. Users can "mark" their current location and then edit the entry's name and coordinates, which enables navigation to those new coordinates.

                  
                                             

                          

              In 1999, Samsung launched the world's first watch phone, the SPH-WP10. It had a protruding antenna, a monochrome LCD screen, and a 90-minutes of talk time with an integrated speaker and microphone.

Some wireless service providers, as an incentive, have also offered the Galaxy Gear as part of a bundle with the Galaxy Note 3.

      The Galaxy Gear uses an Android-based operating system with a minimalistic interface and gesture-based navigation. To pair the watch with a smartphone or tablet as its host device, the user must first install the Gear Manager app. An NFC tag located inside the charging case is used to download the app. Gear Manager uses Bluetooth to coordinate the pairing process and further communication with the device. It can also be used to configure the device's settings (such as the clock display's color and appearance), and to manage and install apps via Samsung App 

     
         The camera app can take photos, or record videos up to 15 seconds in length. Photos and videos can be stored to the device's internal storage, or immediately transferred to the user's phone or tablet. Users can also record up to 5 minutes worth of voice memos. A media controller for music or video being played by the phone or tablet is also provided
