If you want a smart watch that uses cellular data without using up the battery, consider upgrading to the Samsung Gear S3. A close cousin to the Gear Sport, the S3 has all the perks of an LTE smart device (downloading apps, texting, checking email) and, unlike the Apple Series 3, it won’t quit after three hours. In fact, you could feasibly get 72 hours out of this LTE version of the Samsung Gear Sport.
Inside the Charge 3 are an accelerometer, gyroscope, optical heart rate monitor, and an SpO2 sensor for tracking blood oxygen levels. The Charge 3 is the third Fitbit device to include an SpO2 sensor, following in the footsteps of both the Fitbit Ionic and the Versa smartwatches. However, currently the SpO2 monitor lies dormant inside all of these devices as Fitbit hasn't made use of it yet.
Apple has announced the Apple Watch Series 4. It’s the first real redesign of the wearable since Apple introduced it in 2014, but the changes aren’t so drastic that you won’t recognize it as an Apple Watch. The Series 4 comes with an upgraded display, and you can choose either a 40mm or 44mm model. Even though the screens on the new models are bigger, the overall body of the Watch is roughly the same as previous models, so you shouldn’t notice much of a difference on your wrist.
Why we like it: Apple Watches are the best smartwatches overall because they make it easier than any other wearable device to interact with the messages and notifications relayed from your iPhone. The Series 1, specifically, has all the features most people need at a reasonable price. It looks better than most smartwatches and fitness trackers, on wrists both large and small, thanks to two sizes and an array of finishes and bands (both official and third party). While not every major iPhone app has an Apple Watch partner app, many do, and most respond quickly and are optimized for the watch’s small screen, unlike many of the apps available for Android watches. And the Series 1 Apple Watch does a good job of independently tracking most kinds of workouts where accurate distance tracking isn’t vital,1 and encourages non-workout fitness (like standing and moving every hour). We also like that the Apple Watch lets you easily make contactless payments using Apple Pay, and if you own a Mac, you can unlock it by just getting close to it with your Apple Watch.
The Apple Watch Series 4 is now on sale, and it's the best smartwatch you can buy right now. The redesigned device, which starts at $399 for the GPS model and $499 for the cellular version, is the best smartwatch you can buy. It has a larger display and slightly bigger case size while retaining the same rounded square design the watch is known for. Even more importantly, Apple received FDA clearance for a new electrocardiogram feature that can take a 30-second EKG and diagnose atrial fibrillation.
