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.
Like other Fitbit devices, the Charge 3 takes little effort to set up. It works with Android and iOS devices, and all you need is the Fitbit mobile app to use it. Choose the Charge 3 from the list of devices you can pair via Bluetooth to your smartphone or tablet, and follow the on-screen instructions. After setup, you may want to also edit basic information that the Charge 3 uses when tracking activity, such as your age, height, weight, and the activity metric you care most about (steps, active minutes, etc).
The Gear 2 also includes a gyroscope, an accelerometer, and a heart-rate sensor. It also can control a TV or set-top box remotely using a built-in IR blaster, and it has the ability to function as a stand-alone music player. And its built-in camera—handily built into the watch itself rather than on the band, like the original Galaxy Gear—takes 2-megapixel stills and 720p video.
It doesn't get better than the Apple Watch Series 4. The new slimmer body and bigger screen make it sleeker and more stylish than ever before. The unique modern design works for both men and women. The smartwatch comes in 40mm and 44mm styles to fit wrists big and small. You can buy it in several finishes to match your style and there are dozens of Apple-made and third-party watch bands to make the Watch your own.
All but the Martian Notifier claim some degree of water resistance: the LG, Samsung, and Motorola models can survive underwater up to 1 meter for 30 minutes, the Cookoo2 up to 100 meters, and the MetaWatch up to 3ATM, which is equivalent to 30 meters. Only the Martian and Motorola models claim to have scratch-resistant screens (the Martian has an anti-scratch acrylic crystal and the Moto 3 uses Gorilla Glass 3).
The Passport is versatile in that it works with Android and iOS mobile devices. And it features the ability to make phone calls with its built-in microphone and speaker. You can use voice commands (the Passport leverages your phone's voice recognition system; such as Apple's Siri for iOS devices or Google Now for Android) to control the mobile device from the watch. And because of the analog watch face, you can easily see the time in bright sunlight.
For deeper integration with your Android phone, you can give Google's Wear OS platform a try with Fossil's $275 Q Control touchscreen smartwatch. It lacks GPS and support for NFC payments, which is why the Gear Sport is a better fitness-focused smartwatch for Android users, but Fossil's Google Assistant integration and stylish design make it a solid contender. However, smartwatches with Qualcomm's new Snapdragon Wear 3100 processor start shipping in October, so you may want to hold off until we put them to the test.
