Learn what a smartwatch is, how it works, and what they can be used for. See how a Samsung Galaxy
Watch helps you maintain a healthy lifestyle, stay connected and simplify your daily life.

A smartwatch does more than simply tell the time. It can also tell you valuable information about your health and wellness, track the weather, make texts and calls and keep your calendar for you. Some smartwatches can leverage Artificial Intelligence1 to help make your entire life more streamlined and more efficient.

What is a smartwatch?

Before we get into all the details about smartwatches and what a Galaxy
Watch can do for you, it’s important to start with the basics. A smartwatch
is a portable device worn on the wrist that supports apps and acts as an
extension of your mobile phone in some cases. Depending on the make
and model, they have numerous functions that can have a big impact on
day-to-day life.

What does a smartwatch do?

There are many benefits to owning a smartwatch, from keeping with your health to easy access to apps, smartwatches offer exceptional convenience and versatility. Based on the model of Galaxy smartwatch, you’ll find a bevy of benefits.

1. Advanced health and fitness tracking features that can help you lead a healthier lifestyle.
2. Seamless integration with other Galaxy devices and the wider Galaxy Ecosystem.
3. Convenient access to your favorite apps and services.
4. Long battery life and wireless charging capabilities allowing you to use them throughout the day without worrying about frequent recharging.
5. Personalized style and customization options, including a choice of stunning Galaxy wristwatch straps.2

All of that is before we even dig into the details of what exactly a smartwatch can do. Read on to learn more about the amazing functionalities available on the most recent Galaxy Watches.

Key features of a smartwatch

Smartwatches are packed with capabilities designed to help throughout your day, whether you need a companion in the office, at home, in the gym, out for a run or swim, or while you’re chilling on the couch. Some are built with a specific lifestyle in mind, but most current Galaxy smartwatches share a core set of features, including health and fitness tracking, sleep insights, smart notifications and convenient access to everyday tools.

The latest Galaxy Watches give you two distinct ways to put those features to work. Galaxy Watch9 wraps everyday health, fitness and connectivity into a sleek, comfortable design made to stay on your wrist from first light to sundown. Galaxy Watch Ultra2 takes a more rugged approach, pairing advanced wellness features with the durability and outdoor capabilities needed for trails, water and wherever else you decide to wander. One is made to keep up with everyday life. The other is ready when the everyday goes off-road.

Now let’s explore some key features a little closer.

Tracking health and fitness

One of the most popular reasons to use a smartwatch is to keep track of your health and fitness. Most smartwatches nowadays can handle the same essential functions as a traditional fitness tracker, and some will let you receive notifications, calls and other mobile features. That means you can keep an eye on your health stats like heartrate without carrying your phone along for the ride. Thanks to GPS (Global Positioning System) on Galaxy Watches, you can track activities such as running, biking and swimming3. You’ll find GPS tracking features4 in many of the best Galaxy smartwatches, including the latest Galaxy Watch9 and Galaxy Watch Ultra2.

Galaxy Watch9 is designed to make daily wellness easy to understand, with personalized fitness guidance, running support and health insights that help you follow your progress. Galaxy Watch Ultra2 builds on those capabilities with tools designed for more intense, adventurous workouts, including guidance for navigating trails5 and tracking your performance outdoors.

And don’t worry, your watch doesn’t take a breather when your workout ends. With Samsung Health and innovative BioActive Sensor technology, a Galaxy smartwatch can help you follow a plethora of health stats throughout the day and even while you sleep.

Features like Vitals6 can help keep you aware of changes from your typical patterns during nighttime hours, while Heart Health Score7 brings multiple health factors together into a clearer picture with a single personalized score8. And Fitness Index9 uses your fitness information to provide a daily score and training recommendations to fit your goals. All together, these features are like having a health and fitness coach strapped to your wrist.

Some Galaxy Watches, including Galaxy Watch9 and Galaxy Watch Ultra2, also feature Advanced Sleep Coaching, which analyzes your sleep and gives you personalized guidance to help build healthier nighttime habits. These watches can even help identify signs of moderate-to-severe sleep apnea,10 offering a deeper look at what your body may be doing while you’re counting sheep.

Galaxy Watch also helps you understand how ready you may be to take on the day with Energy Score, powered by Galaxy AI. The score considers factors such as your recent sleep, heart rate, exercise and activity, giving you a simple way to check in with your body before deciding whether today calls for a personal best—or a well-earned recovery day.

Text and voice messages

One of the features that makes a smartwatch most like a smartphone is the ability to send both text and voice messages. With Galaxy Watch, this is supported by our pre-installed Messages app that allows you to create new messages or view incoming messages and send replies. Plus, if you’re more than 10 yards away from your connected phone, LTE-compatible versions of Galaxy Watches will use mobile data to operate so there’s no need to carry your phone with you when you’re out pounding the trails, or halfway up a mountain face.11 Galaxy Watch9 and Watch Ultra2 put AI to use to become your personal AI assistant.12 Just lift your wrist and speak a command to text a friend, make a call, get directions, add a meeting to your schedule and much, much more. Galaxy Watch puts a convenient control center right on your wrist.

Notifications

If your phone and your smartwatch aren’t in the same room, you’ll still be able to see any notifications pop up on the watch’s interface. This
is a very handy feature that means you don’t need to carry your
phone around with you everywhere, especially when you’re doing
things that might need your hands to be free such as cycling,
swimming, running or flipping burgers out on the patio.

Mobile Wallet

Many smartwatches now support the ability to make contactless payments in a super straightforward way using Tap to Pay13. Galaxy Watches, including the Galaxy Watch9 and Watch Ultra2, utilize the power of Samsung Wallet14 to store your card information, meaning it’s readily accessible at the click of a button. You no longer need to have your wallet and phone on you when you’re out and about. And don’t worry - it’s just as secure as it is on your mobile phone.
