This smartwatch buying guide breaks down all the different factors you should consider when deciding whether the Apple Watch, a Fitbit or offerings from other top wearable makers is right for you.

The best smartwatches we've tested are all excellent in their own right, but they're not one size fits all. From big technology brands such as Apple, Samsung and Fitbit to traditional watchmakers like Tag Heuer and Fossil, dozens of companies have smartwatches that deliver notifications, apps and more to your wrist. Upcoming modes like the Apple Watch 6 and Samsung Galaxy Watch 3 will push the capabilities even further.

Although features and designs vary, smartwatches can help save you time and keep better tabs on your health. Most have have built-in fitness metrics, such as a heart rate sensor and GPS. Some can act as an extension of your phone, while others are marketed as a health-focused devices, like the Fitbit Versa 2 and Samsung Galaxy Watch Active 2.

Some smartwatches, such as the Apple Watch Series 3 and Apple Watch Series 5, even work independently of a phone. But if you want something that gives you a break from your notifications, one of the best fitness trackers might be better for you.

We've also reviewed a number of affordable options to see which of the best cheap smartwatches are worthwhile. So whether you're on a budget, have specific fitness goals or want to be more productive, here's a smartwatch buying guide for determining which wearable you should get.

Smartwatch buying guide: Quick tips

  • Don't buy a smartwatch without confirming that it will work with your smartphone. For example, Apple Watches only work with iPhones. Google's Wear OS platform and Samsung's Tizen watches will work with both Android phones and iPhones, but with fewer features than if you use them with Android devices.

  • Pick a watch with a heart rate sensor and GPS (to track your runs) if you're a fitness buff.

  • Pay attention to rated battery life when shopping. Hybrid smartwatches that look more like analog timepieces tend to have the longest battery life, but they don’t have touchscreens.

  • Check that the watch band's clasp or buckle is easy to use and easy to swap. Also make sure that it’s easy for you to find replacement bands.

  • The selection of apps is a factor, but it’s not as important as compatibility, design and other features.

Smartwatch buying guide: OS and phone compatibility

Because most smartwatches are designed to serve as companions to your smartphone, device compatibility is very important. For instance, Samsung's Tizen-powered Galaxy Watch and Galaxy Watch Active 2 work with multiple Android handsets as well as iPhones. Although you should note it’s easier to use those watches with an Android device, and specifically a Samsung one.

The Fibit Versa 2 works just as well with Android phones as it does with iPhones. Android phone owners do get one extra feature: quick replies to incoming text messages.

Google’s Wear OS runs on smartwatches from Fossil, LG, Huawei and others. It's most compatible with Android smartphones, although some will work with the iPhone with limited features. Google makes it easy to check whether your smartphone is compatible: just go to from your smartphone browser.

Not surprisingly, the Apple Watch only works with the iPhone. The preinstalled Apple Watch app for the iPhone is where you'll find the watchOS App Store. There, you can install the watch versions of your favorite iOS apps or find new ones: The store features everything from games to fitness-tracking apps to extensions of your most-used productivity apps so you can get Slack notifications or see Trello cards.

Bottom line, don't buy a smartwatch unless you know that it will work with your smartphone.

Smartwatch buying guide: OLED vs. LCD Display 

Most smartwatches use a colorful LCD screen or AMOLED display, which let you view photos, apps and other content in richer color, and tend to be brighter. The trade-off is shorter battery life, though smartwatch makers are improving the devices' efficiency. Some can last several days, if not weeks, but you'll want to opt for a black-and-white display if you want the longest stamina.

Pricer smartwatches offer crisp OLED displays instead of LCD displays to allow for slimmer designs. Apple developed its first OLED display to make the first-generation Apple Watch as thin as possible. But it should be noted Samsung created the first ever, OLED smartwatch, the Galaxy Gear, in 2013.

Smartwatch buying guide: Touchscreen vs. touchless

Opting for a touchscreen on your smartwatch would seem to be a no-brainer. But it can be difficult to select items on a smaller touch display, and some of the gesture-based interfaces aren't intuitive. 

Wear OS does a nice job of presenting card-based notifications you can easily dismiss with a swipe, but there's a lot of swiping involved to get to other apps and options within apps. You can, however, switch between cards with a flick of your wrist.

Apple opted for a combo approach for the Apple Watch, offering a touch display and both a digital crown and side button on the right side. You can use the crown to quickly zoom in on content or to scroll, and the screen uses Force Touch, which knows the difference between a tap and a long-press. A press of the side button brings you to your dock of frequently used apps.

The Samsung Galaxy Watch and Samsung Gear 3 have a bezel that you rotate to scroll through menus. These are used in combination with touch.

Smartwatch buying guide: Design and Personalization

The better smartwatches offer a choice of straps and/or the ability to swap them out for a third-party option. This is important if you want to personalize the look of your device.

Most smartwatches today offer plenty of customization options before purchase. For instance, you can pick the band color and material, as well as face color, finish and size for such watches as the Moto 360 and the Apple Watch.

Keep in mind that comfort counts for a lot, as does the ease with which you can fasten the watch to your wrist. We would definitely avoid any smartwatches with cumbersome clasps that require too much force to open and close. Thankfully, most new watches use standard buckles.

More and more smartwatches are sporting round faces now, making them look more like traditional timepieces. Newer ones are getting slimmer and smaller.

Traditional watchmakers are also joining the fray with Android Wear devices that combine the style of an analog watch with the smarts of Google's watch operating system. Movado, Tag Heuer, Emporio Armani and even Louis Vuitton have jumped on board the smartwatch bandwagon with fashion-forward devices (and price tags to match).

Smartwatch buying guide: App selections

The smartwatch category is maturing, and some models now have hundreds or even thousands of apps.

The Apple Watch has the most well-rounded app roster thus far, with more than 20,000 available, including ESPN, MapMyRun, Uber and even Rosetta Stone. You can do everything from control your Philips Hue lights (and all the other best smart home devices) to order out lunch with Seamless.

There's a dedicated Apple Watch App Store for installing those apps in the Apple Watch app for iOS. Check out our roundup of the best Apple Watch apps for more on what to expect.

Google's Wear OS also has thousands of apps optimized for its platform. You install apps directly on the watch itself, rather than having to go through your smartphone first. Wear OS has many of the same apps that watchOS does, including Lyft, which enables you to schedule a ride, and WhatsApp, which lets you reply to messages with your voice.

Other proprietary systems, especially Samsung's Tizen OS, tend to be deficient in the apps department. Tizen's offerings are growing, though. 

Fitness features, heart rate and GPS

As fitness trackers continue to attract attention, smartwatch makers are getting in on the action by integrating activity-monitoring functions. Some smartwatches depend on your smartphone for activity tracking, but most at least have a built-in pedometer for tracking steps.

If you plan to use a smartwatch primarily for working out, you may want to consider fitness trackers with smartwatch-like features, such as the Fitbit Versa or the Garmin Vivoactive lines, both of which let you change the watch face and read notifications. The Versa goes even further by offering female health features, such as the ability to log periods and record symptoms, as well as compare your cycle against health stats like sleep and activity.

Most Wear OS devices have a heart rate monitor built in, but we haven't found them to be as reliable as dedicated fitness trackers like Fitbit Charge 4. The Apple Watch heart rate sensor proved more accurate in our testing.

In addition to heart rate monitors certain models have GPS, which makes them more attractive to those who want to go running or biking outdoors, and want to track their distance and pace. However, keep in mind that using GPS will have a significant impact on battery life.

Calling and mobile payments

Do you want to make calls from your wrist? Some have built-in LTE so you can leave your phone at home — at least in theory. AT&T’s NumberSync and Verizon's NumberShare feature let you use the same number on your phone and the watch, and your phone doesn't need to be nearby or turned on. You will have to pay for a separate data plan for your smartwatch — about $10 per month — which is something to consider if you want to take advantage of its cellular connectivity.

Many smartwatches have NFC chips inside, which means you can use them to pay for stuff, even without a phone nearby. All Apple Watch models have Apple Pay enabled, even without an iPhone nearby or an LTE connection. Wear OS watches that support Android Pay include the LG Watch Sport, Huawei Watch 2 and Tag Heuer Connected Modular 45. Samsung’s own mobile-payment system, Samsung Pay, works on all of its newest models.

Garmin and Fitbit, which are known for their fitness-focused watches, have added mobile payments to their latest devices, too.

Battery life and charging

Most smartwatches with color screens tend to last one to two days between charges (and sometimes less than one day), so you'll want to consider how often you're willing to keep plugging in your watch.

Watches with voice capabilities won't last nearly as long when you use them as phones, but that's to be expected. The Apple Watch lasts about 18 hours of mixed use on a charge.

Most smartwatches, including the Apple Watch and Samsung Gear Sport, use wireless charging, which is convenient: You don’t have to plug your device directly into a charger; instead, you lay it flat on a charging puck. 


With the exception of budget devices from no-name brands, most smartwatches will cost between $100 for older devices, all the way up to $1,600 for the Tag Heuer Connected. You'll find most smartwatches in the $200 to $500 range, depending on features and accessories. 

For example, the Apple Watch Series 5 starts at $399 for a basic aluminum case and silicone band without built-in GPS, but the cost is north of $1,399 for the ceramic case or designer variants.

You'll need to decide what combination of form and function works best for your budget.
