Built-in apps -

You can read an email, flag it, mark it as read or unread, or delete it. Choosing from a list of preset or customised replies. Or to write a longer message, use Handoff to continue on your iPhone.

Control the music on your iPhone. Or leave your iPhone at home and listen to your favourite synced playlist right from Apple Watch using wireless Bluetooth headphones.

See who’s calling without having to reach for your iPhone. Use the built‑in speaker and microphone for quick chats, or instantly transfer calls to your iPhone for longer conversations. To mute an incoming call, just cover Apple Watch with your hand.

Apple Watch gives you a gentle tap to let you know when you have a new message. See who it’s from and to read the full message. Respond with a preset message, dictate a reply or record an audio message.

See what’s next in your day or week. Apple Watch sends you meeting reminders that appear on your watch face. When you get calendar invitations, you can accept or decline immediately and even email the organizer using preset responses.

You can do with Siri — if not more — and in less time.Siri works in the main Home screen mode. So, you don’t need to open an app first, to enable Siri app — just lift your wrist and speak - “Hey, Siri” , without having to press the Digital Crown button.Alternatively, you can press and hold the Digital Crown button to activate Siri.To work at Siri, say “Hey, Siri,” followed by your question or command. Like as-

 “Hey Siri, open the Workout app.” “Hey Siri, where’s the nearest coffee shop?” “Hey Siri, call Elizabeth.” “Hey Siri, Text Julie and Frank ‘Where are you guys?’”

Open the Workout app, then choose one of popular workouts options.You can set a Calorie, Distance, or Time goal. Your Apple Watch will alert you when you reach your goal.Workout app uses a heart rate sensor and GPS.For GPS accuracy when you walk, run, or cycle outdoors, select the appropriate Workout and bring your iPhone. This will also help calibrate the accelerometer in Apple Watch for times when you don’t have GPS, such as during workouts or when you're running outside without your phone.

Get directions from your current location. Apple Watch shows you the best route. You can also use Siri to search for nearby restaurants, petrol stations and shops.

With Apple Watch, your favourite photos are always close at hand. Use the Digital Crown to zoom in to individual images, or swipe to browse through them one at a time.

Apple Watch can be a viewfinder for the iSight camera on your iPhone. So you can take a perfect selfie or join the group shot. See a live preview of what your iPhone sees, then snap the photo or set the timer on the camera.

Apple Watch lets you manage, label and edit multiple alarms with ease. Use the Digital Crown to set your wake-up time, or simply ask Siri.

Apple Watch presents this popular watch function in digital, analogue or hybrid view. There’s also a graph view, which charts a real-time average of your lap times — something you won’t find on other watches.

Keep track of timed events precisely and easily. As the timer runs, an orange line moves round the dial, giving you a visual sense of how much time has passed and how much is left.

Check the weather where you are or for any location around the world. See a detailed report for the day or get the week’s forecast. The day’s conditions are arranged like a watch face, so you get a quick visual snapshot of the weather for the whole day.

Wallet lets you keep your boarding passes, tickets and loyalty cards on your wrist, and alerts you when it’s time to use them.

Don’t worry about losing the remote. Now you can control Apple TV straight from your wrist. Swipe around the main menu, scroll through lists and choose what you’d like to watch.

Doing business in another time zone? With one look, you can check the time in different cities around the globe. You can add new locations from your iPhone at any time.

Enable or disable Airplane mode, Bluetooth and Do Not Disturb. You can also turn mute on or off, and even ping your iPhone when you’ve misplaced it.

Easily keep up with the stock market. See current prices, point and percentage changes, and market cap. Each stock features a graph view that lets you track its performance over the past day, week, month or six months.

Activity

The Move ring shows how many active calories you've burned so far.

The Exercise ring shows how many minutes of brisk activity you've completed so far.

The Stand ring shows hours in which you've stood and moved for at least a minute.

o If you need both hands while walking, for example to push a stroller, you can still earn Exercise credit by using the Workout app. The Activity app relies on arm motion and an accelerometer to track movement.

Activity can automatically track your daily movements. You can check your progress, meet goals, and customize notifications.

Simply hold the connector near the back of the watch, where magnets cause it to snap into place automatically.

How to charge your Apple Watch

Apple Watch is charged by means of inductive charging, using a cable.

Apple rates the device's battery for 18 hours of mixed usage.

If the watch's battery depletes to less than 10%, the watch will enter a "power reserve" mode, which allows the user to continue to read the time for an additional 72 hours.

The watch then reverts to its original mode when recharged.

Components

• A plastic tool is used to remove the device’s lithium-ion battery.• The display is carefully removed.

• The Taptic Engine is the tiny motor that provides force feedback whenever the watchface is pressed or when the user receives a notification.

• We see that it is attached to the Apple Watch’s speaker.

• This is antenna assembly, which likely controls the watch’s Wi-Fi and Bluetooth functionality.

• Apple Watch’s casing is the S1, the integrated computer chip that gives the device its smarts.

• This is the Digital crown bracket.

• At the bottom of the watch case that component serves as the Apple Watch’s heart rate monitor.

• The device may also be able to measure a user’s blood oxygen level, but Apple hasn’t promoted this feature.

An entire computer architecture on a single chip• This package is filled with resin for durability.

• 8 GB flash from SanDisk and Toshiba

• Wireless charging chip

• Touch controller

• Integrated accelerometer

• Wi-Fi/FM/BT combo chip

• Samsung is said to be the main supplier of key components, such as the RAM and NAND flash storage, and the assembly itself.

Brilliantly scratch-resistant sapphire crystalNext to diamond, Sapphire is the hardest transparent material on earth. That makes it ideal for protecting the Retina display. To harvest the crystal, we use a very thin diamond-cutting wire and polished for many hours to produce the desired finish.

Sensitive enough to tell a tap from a pressForce Touch uses tiny electrodes around the flexible Retina display to distinguish between a light tap and a deep press.

not just a Display

o When you press two fingers on the screen, the built-in heart rate sensor records and sends your heartbeat.

o This technology is based on a very simple fact: Blood is red because it reflects red light and absorbs green light. Apple Watch uses green LED lights paired with light‑sensitive photodiodes to detect the amount of blood flowing through your wrist at any given moment. When your heart beats, the blood flow in your wrist — and the green light absorption — is greater. Between beats, it’s less.

o By flashing its LED lights hundreds of times per second, Apple Watch can calculate the number of times the heart beats each minute — your heart rate.

o The heart rate sensor can also use infrared light.

o Apple Watch attempts to measure your heart rate every 10 minutes.

watchOS 2 PreviewNew looks of your watch face • New watch

facesPhoto. Pick a special image from the Photos app on your watch and set it as your watch face.Photo Album. Every time you raise your wrist, a different image from your any photo album you select, will appear on your watch face.Time-Lapse. Choose from a selection of dazzling time-lapse videos shot over 24 hours in iconic locations around the world.

• More ways to customize your complicationsComplications are important pieces of information you can see right on your watch face, like your Activity rings or upcoming Calendar events. So you can easily check your United flight times or keep eye on your battery charge.

• See your future with Time Travel.A new feature in watchOS 2, you can turn the Digital Crown to see what’s happening — and what’s already happened — yesterday, today, and tomorrow. You can see what the weather will be like for your lunch date tomorrow. Check your schedule for later today. A press of the Digital Crown gets you back to the current time.

• Put your watch into Nightstand mode.Now you can use your watch even when you’re done wearing it for the day. Just connect the charger. Apple Watch will automatically go into Nightstand mode, a digital display that illuminates whenever you touch the screen, the Digital Crown, or the side button.When an alarm sounds, you press the side button to turn it off, or the Digital Crown to snooze.

Faster, more powerful apps.

• Apps now run natively for better performance.With watchOS 2, many apps are native apps, which means they run entirely on your Apple Watch. So they load more quickly and have even greater capabilities.

• Do even more with apps.Apple Watch apps have more possibilities with watchOS 2. Apps can now take advantage of features like the Taptic Engine, Digital Crown, accelerometer, heart rate sensor, speaker, and microphone. For example, the Ping app uses the accelerometer to measure the speed of your golf swing. Strava uses the heart rate sensor to gather and display data during workouts.

• Reply to email.Apple Watch already lets you receive email on your wrist. With watchOS 2, you can respond, too. Just tap Reply at the bottom of a message. Then dictate a response, or choose from a list of relevant, preset replies.

• Send more colorful sketches.Digital Touch lets you draw and send sketches to other Apple Watch wearers. And now you can express yourself in multiple colors, so you can get more creative with your digital art.

• Ask Siri to do more for you.With watchOS 2, Siri is an even more versatile personal assistant. Now you can use your voice to do things like start a specific workout, check your Glances, get transit information, look up a word in the dictionary, and calculate a tip.

Familiar apps with new functions.

• Add more friends.WatchOS 2 lets you add multiple Friends screens, each of which can hold up to 12 contacts. And you can add a friend from your contacts directly on your watch. You can also use the Apple Watch app on your iPhone to organize your friends into groups you name yourself.

• Get public transport information on your wrist.When it comes to directions, Maps shows you the best route from your current location. watchOS 2 adds Transit, so you can combine more kinds of transportation in a single trip. In select cities around the world, you’ll see detailed maps and accurate train, metro and bus timetable. And you’ll get walking directions to and from your stop.

Protect your watch with Activation Lock.WatchOS 2 includes Activation Lock, a new security feature. Activating your watch requires your iCloud Apple ID and password, so in the event that your Apple Watch is lost or stolen, your information remains safe.

New opportunities for developers.

If you’re a developer, WatchKit for watchOS 2 allow you to access the unique features and innovations of Apple Watch. So you’ll be able to create apps that are truly designed for the wrist.

Rather Slow.Apple Watch doesn’t work as fast as you’d like it to. It is rather slow in importing data from your iPhone via Bluetooth or Wi-Fi. There are times; it takes a lot of time in loading third-party apps. On some occasions, it seems to have got stuck in loading notifications.

Merely 75 MB of Photos Storage.You can store tons of your favorite photos on your iPhone or iCloud and save your precious Apple Watch from being cluttered for space, but having merely 75 MB storage for photos doesn’t make any good impression at all. Apple Watch has total 8GB of internal storage out of which there is only 2GB of storage for music. No matter which model you choose, the watch has the same storage capacity.

Apple Watch Price Is Ridiculous High.Apple Watch's price is way higher than we were expecting to pay. The price for Apple Watch starts at $349 and goes up to $17,000. The differences in Apple Watch prices are down to the metal and glass of the watch.

Demerits in apple watch

Battery Barely Lasts a Full Day.Apple Watch’s battery would hardly last a full day after an extensive use. A look at the early reviews that have come from many experts suggest you that you would have to hunt for power source more often to keep your watch charged up.

Too Dependent On iPhone.Apple Watch doesn’t have its own GPS technology, it would heavily rely on iPhone to assist it in carrying out many functions like sending message, or making a call. What if you have forgotten to take your iPhone along, wouldn’t it make the watch handicap?

Still More of a Fashionable Stuff.Your iPhone can do almost all the activities that an Apple Watch can do. So, why go for this ultra-expensive watch just for the sake of making a fashion statement?

Not Consistent Enough.As Apple Watch turns its screen on only when you look at it to see time, there is not much consistency with this function. Sometimes Apple Watch doesn’t activate its screen even when you tap on it. At times you have to move your wrist in upward motion, to make it activate its screen.

THE GOOD. The Apple Watch is a beautifully constructed, compact smartwatch. It's feature-packed, with solid fitness software, hundreds of apps, and the ability to send and receive calls via an iPhone.

THE BAD. Battery only lasts a little more than a day; most models and configurations cost more than they should; requires an iPhone 5 or later to work; interface can be confusing; sometimes slow to communicate with a paired iPhone.

THE BOTTOM LINE. Apple Watch first-gen shortfalls make it feel more like a fashionable toy than a necessary tool.
